Croeso - welcome

I write this editorial from my hometown of Llanelli under a cloudless blue sky and a beautiful warm summer’s day. It’s a reminder of rising temperatures in Europe and the need to be aware of the potentially lower oxygen levels in our fish culture operations and the need for aeration and supporting technologies to optimize conditions for very sensitive fish such as trout.

The farming of rainbow trout is often featured in this magazine and is globally an important fish actually my favorite by far compared to salmon. The trout is such a versatile fish and can be found throughout the UK having adapted to varying conditions and is so underrated in many ways.

I was brought up to appreciate this species having fished my river for wild brown trout with so many expeditions with my father in my youth. Wild brown trout has a wonderful flavor and excellent eating qualities with its white flesh and nutritious value.

The rainbow trout for me is a tastier fish than farmed salmon but we have some challenges to improve its image to the consumer with respect to appeal as an easy but bony fish to

cook and serve. Sadly, so many trout farmers have closed down their farms in the UK due to financial pressure and the industry has diminished someway in the last decade compared the boom years when fish farms were more abundant.

When I was first in my old institution in Plymouth there were at least least five farms in close proximity to Plymouth in Devon that supplied fish for my feeding trials. Now only two farms with fingerling trout sources are available in the other neighboring counties of Somerset and Dorset. It was getting increasingly very difficult to obtain fish for studies and I am sure this trend will continue to impede procuring of good quality fish for research in the future.

The SW of England is more renowned for its shellfish farming than finfish aquaculture so perhaps fate has allowed me greater opportunities in new regions of the UK to restore an aquaculture research base of international class as my final legacy before I retire one day.

One thing about my new position at Harper Adams University is my chance to read more and get into scientific papers in depth. I also get to meet new contacts from industry and the agri-tech sector that is becoming more interested in aquaculture within the UK. We need this to stimulate the concept of urban and city aquaculture enterprises through the developments in RAS (Recirculation Aquaculture Systems) and Aquaponics installations. We see this happening in London and in Holland with great potential to expand throughout the world. I would hope to report on such aquaculture technologies in future here with some excellent examples.

In the meantime our latest issue is packed as usual with news features and topical reports varying from technical developments to the more scientific level.

The summer issue of the magazine contains articles with a much keener focus than usual on the world of fish farming technology, as well as some fine reporting from the recent Aquaculture UK show in Scotland.

As well as the event reporting, we also have our usual array of contributions from our expert columnists as well.

Seabream is this edition’s species focus, with articles also focusing on Digestable energy, micro-algae and water disinfection with ultraviolet light. We also have a very interesting article about AKVA’s new net cleaning ROV. Continuing our fish farming technology theme, BOC’s Stefan Dullstein is this month’s interviewee.

In the next issue I will have celebrated (If that’s the correct term!) 30 years of continuous service in academia and achieved so much with the help of so many over an extremely interesting period of my life and more recently, unexpected challenges too.

It has been an interesting three decades having learned so much about this dynamic and ever changing industry.

There is an ever-increasing amount of information to assimilate and I am pleased that this magazine continues to play a leading role and voice within its specialised field.

Largest event delivers for AWF in Indonesia

here have only been two WAS events in Indonesia; the first was just after AwF had started in 2005 in Bali, and the second was the Asia Pacific Aquaculture (APA)2016 in Surabaya at the end of April.

The people flocked to Surabaya where they provided 240 exhibition booths and eleven rooms of conference over three crammed but exciting days at Grand City complex in the centre of the large city. The numbers may well have expected to be down a little on usual because of the clash with the Seafood Expo Global in Brussels but, primarily due to the local Indonesian support, WAS saw record numbers exceeding 5,500 people attend.

Indonesia, of course has a rapidly expanding aquaculture industry – nearly 20 percent increase in the last five years in hectares in aquaculture production and over 50 percent per year increase in tons produced every year for the last 10 years. For those visiting from EU, USA, Australia, etc it was important to see the government and industry partnership, which is obviously needed to maximise aquaculture outcomes.

You need a formula of a government

In order for a country to achieve what Indonesia has over these passed years you need a formula of a government that sets the governance, infrastructure and incentives to engage people in aquaculture coupled with industry groups that grasp the opportunities and in the background you need active service industries that supply education, equipment, feed and all the other ingredients. You can see in Indonesia that this is happening.

Of course you also need to be blessed with geographic location and the Indonesia nation is made up of thousands of volcanic islands, known for its natural beauty with beaches, volcanoes and jungles sheltering elephants, tigers and Komodo dragons. It is a great recipe.

WAS-APC put on a great show in Surabaya and along with AwF importantly engaged the students in a terrific session followed by a Students Reception which saw many talented young people engage and give a glimpse what could be to come for the burgeoning aquaculture industry in the future.

An aquaculture competition, national dress competition, cat-walk competition and a talent show ensured that everyone had a great chance to ‘strut their stuff’ and benefit from the prize money on hand.

In the conference student session AwF Directors Albert Tacon and Roy Palmer gave their own unique stories of how their careers evolved within the industry.

The AwF Session included sessions about AwF activities, funding opportunities; women in aquaculture and a number of talks by the WAS-APC students and female aquaculture people who secured scholarships

to attend Asia Pacific Aquaculture 2016. Funding for this opportunity was provided by WAS-APC, and Aquaculture without Frontiers facilitated the process.

All of the presentations have been posted at http://www. aquaculturewithoutfrontiers.org/education/slideshows/

AwF women’s network

Typically the women’s network session was an interesting discussion and well led by Dr Janine Pierce (soon to take over the Secretariat of the AwF Indigenous Network) with great contributions from WAS-APC Directors, May Myat Noe Lwin and Bibha Kumari, with excellent presentations from Arlyn Mandas, Vaishali Joshi, Renata Melon Barroso, Menaga Meenakshisundaram and Nikoleta Ntalamagka.

The AwF Women’s Network is now over 550 people strong thanks to its Secretariat, Julie Kimber, and we expect that will now continue to grow as newly elected AwF (USA) director, Sally Krueger, is going to take special interest in this area.

Further on the Women’s Network the last two Women of the Month have been Dr Shakuntala Haraksingh Thilsted (May 2016) and Dr Doris Soto (June 2016).

Dr. Thilsted, Research Program Leader, Value Chains and Nutrition at WorldFish, was awarded for the exceptional contribution her work has made in creating food-based systems to overcome micronutrient deficiencies in low-income countries across Asia and Africa. Dr. Soto, recently retired from FAO, has worked tirelessly within a male dominated global government organisation, not only promoting aquaculture but also endeavoring to create a culture that is more conducive to women’s involvement.

Along Doris’s journey she has built a solid reputation for developing and increasing capacity and capability enabling the advancement of food security for disadvantaged people.

Nikoleta Ntalamagka spoke about her home county of Greece and the issue of Syrian refugees and this created much discussion about how we could all assist. Nikoleta has also emerged as a leader of students and is helping AwF establish the Students Network along with new AwF (USA) board member, Professor Michael Lee. Over 350 people joined the Students Network in the first couple of weeks so this augers well for the future.

We were very pleased that Lian E.Heinhuis was able to be a special guest presenter for AwF. Lian is an Associate Analyst working specifically on Seafood and works with Gorjan Nikolik senior industry analyst on food and agribusiness for Rabobank International and AwF Director.

Lian presented on the various Rabobank organisations including Rabobank Foundation which pursues its objectives by supporting cooperatives or memberbased organisations which offer an opportunity to save, borrow or insure and has recently signed a contract which is engaged in Indonesia.

AwF receives first Rabobank funding

The timing was excellent as AwF had just received its first Rabobank funding which is going to assist with the training of women in Vakkom, Kerala, India. We anticipate that the project will get under way in July once all of the contracts have been approved and signed. We are very excited about this, as are our MoU partners, Organic Life and the people of Vakkom.

We are also grateful to Dr Dinesh Kaippilly for his efforts in linking the opportunity and we hope that this will be the first of many such activities in the area.

Another AwF board member, Polly Legendre, is using her skills to create a branding strategy for AwF. Developing a long-term plan for the development of the brand to achieve specific goals is something we have never attempted so will be interesting to see what comes of this. On the subject of strategies, DOS O’Sullivan, Australian director, is working on improving and updating the Risk Strategy.

Aquaculture without Frontiers (UK) CIO has had its first meeting in Cheltenham, Gloucestershire, UK and appointed Clifford Spencer as Chairman – Clifford was recently appointed Aquaculture Ambassador to New Partnership for Africa’s Development (NEPAD) which is expected to be a major driver of a new African strategy for the organisation.

The important difference with the UK to other AwF’s is that the CIO is equally shared between AwF and Milling for Life. Whilst ‘Aquaculture without Frontiers (UK) CIO’ is the chosen common name we will be a charity representing both aquaculture and milling. In this respect the Objectives of the organisation are explicit.

The UK operation owes much to Simon Birks as he organised all of the approvals through the government channels in the UK. Simon spoke at some length at the meeting highlighting the role of a Trustee of a CIO as well as the constitution; specifically highlighting the objects of the CIO. The original, Trustees, namely Roger Gilbert, Tuti Tan and Roy Palmer appointed Clifford Spencer, Janice Spencer and Simon Birks as Trustees. A Management Task Force led by Darren Parris (UK) and Roy Palmer (International) was agreed.

Subsequently, José Villalón has agreed to join the Trustees of the CIO in UK. José Villalón is Corporate Sustainability Director at Nutreco, a company based in the Netherlands committed to improving the sustainability of the aquaculture sector. José is well known in the industry as he joined World Wildlife Fund in 2007 and led its aquaculture program for six years; managing the initiative called the Aquaculture Dialogues which involved over 2,200 global stakeholders that created environmental/ social standards for 12-species of aquaculture commodity products including salmon and shrimp. With WWF and partners, José co-founded the independent Aquaculture Stewardship Council (ASC) where he was the Chairman of the Board for its initial four years. We look forward to having José on board our exciting new UK operation and learning from his vast experience. @AwFComms

Sustainability in aquaculture: Evonik turns salmon, shrimp, and more into vegetarians

E

vonik scientists’ long-term intention is to turn salmon, shrimp, and other marine animals into vegetarians.

They are thus playing an important role in protecting marine resources. To that end, they are looking to replace the fishmeal and fish oil produced from wild-caught fish that is used in feeds. Farmed fish play a key role in providing healthy nutrition for the world’s population.

“Thanks to modern fish farming concepts and our amino-acid products, it is already possible to achieve significant reductions in the proportion of fishmeal used in feeds. Now we’re working on sustainable alternatives to fish oil,” explains Christoph Kobler, who heads the Sustainable Healthy Nutrition Product Line at Evonik.

Evonik is one of the world’s leading providers of amino acids and aminoacid derivatives for modern animal nutrition. The company sees itself as a technological leader in this field, and is expanding its product portfolio accordingly to encompass healthy and sustainable animal nutrition.

According to estimates from the UN Food and Agriculture Organisation (FAO), some 147 million metric tons of fish were consumed throughout the world in 2014—over half of which was the product of aquaculture. And demand is rising: in order to be able to feed the growing global population, another 50 million metric tons will be needed by 2030. Because the oceans are already overfished and the fish catches are stagnating, the UN organisation believes that this additional demand can only be met through aquaculture.

Certain fish and crustaceans raised on aquafarms—such as salmon, trout, and black tiger shrimp—are actually carnivores or omnivores. As such, feeds for these animals include fishmeal.

Fishmeal contains important amino acids that the animals need to grow.

Some three-quarters of the fishmeal and fish oil produced worldwide are channeled into aquaculture, representing a major strain on marine resources.

In order to turn salmon, shrimp, and other aquatic species into vegetarians— and protect the oceans in the process— it is not enough to substitute fishmeal,

an animal source of protein, with soy or another plant-based source. The resulting feeds would not contain the right composition or amount of amino acids such as methionine to meet the animals’ needs.

Because their ability to utilise their food would then not be optimal, the animals would have to consume more protein overall and, as a result, would excrete nitrogen-containing metabolites unused. As a consequence, this would waste scarce resources and pollute the water with animal waste beyond what is necessary.

Shrimp feed: Part of highly efficient, sustainable nutrition for farmed shrimp, AQUAVI® Met-Met minimises the use of fishmeal in feeds and reduces marine pollution. Shown here (montage): a whiteleg shrimp (Litopenaeus vannamei) with a feed pellet.

Evonik researchers began looking for a solution to this problem nearly ten years ago, developing special amino acids and amino acid derivatives for fish and crustaceans aimed at making fishmeal largely unnecessary in aquaculture in the future. The underlying principle is to selectively add amino acids such as methionine and lysine to vegetable-based feeds, improving them to the point where salmon and other marine animals can make optimum use of vegetable proteins as well.

The most important task here has been to develop products tailored to the needs of individual fish species.

Take salmon, for instance: In 2008, 40 percent of salmon feed was made up of fishmeal, but this figure has since come down to an average of just 10 to 15 percent. Feed manufacturers are already working at full steam

to introduce feed concepts that can completely do without fishmeal.

Now, after intensive research, there are plans to transfer this success to shrimp. The challenge here is that the feeding behaviour and digestive systems of crustaceans like shrimp are entirely different from those of fish. Whereas salmon are predatory fish that snatch up their food the moment it enters the water, shrimp eat their food very slowly from the seabed. As a result, highly watersoluble components leach out of the feed pellets before the shrimp can eat them. In addition, the supplemented methionine has to be present at a certain time—right when amino acids become available from the protein digestion process.

Only Evonik researchers have managed to develop an improved source of methionine that shrimp can consume and metabolise at the right time and in the right amount. This new dipeptide consists of two methionine molecules and does not dissolve readily in water, which prevents it from leaching out of the feed as quickly.

The shrimps themselves have to cleave the molecule, and this makes the methionine available for protein synthesis at the same time as the other products of digestion. The company is currently putting its first production facility for the new product into operation in Antwerp, Belgium.

The company’s researchers are now working on replacing fish oil, the second important animal product in fish feed.

“This would mean it would be possible to entirely eliminate the use of marine resources like fishmeal and fish oil in the production of fish feed,” said Mr Kobler.

Evonik is working with DSM Nutritional Products Ltd. of Kaiseraugst (Switzerland) to develop an algae-based omega-3 fatty acid product for use in animal feeds. Like people, animals also need a certain amount of this essential, long-chained polyunsaturated fatty acid in their food in order to sustain healthy growth. In aquaculture, this nutrient has largely come from the fish oil contained in feeds. DSM and Evonik intend to use sustainable biotechnological methods to harness marine algae in the production of omega-3 fatty acids.

he Marlborough District Council and the Ministry for Primary Industries will establish a Marlborough Sounds Salmon Working Group to consider options to implement the Best Management Practice Guidelines for Salmon Farming in the Marlborough Sounds (the guidelines). Other agencies that will have input into the process include the Department of Conservation and the Ministry for the Environment.

The working group will meet starting in July and provide recommendations to Marlborough District Council and the Government on implementing the guidelines.

Ministry for Primary Industries Deputy Director General Ben Dalton said the public, the council, government and industry have shown a commitment to implement the guidelines.

“These guidelines were developed by local and central government, industry and scientists in 2014 to set out recommendations for sustainable salmon farming in the Sounds.

“The next step is to work with iwi, the community and industry to look at options for salmon farming in the Marlborough Sounds so that the best environmental, social and economic outcomes are being realised,” he said.

Working group membership is currently being finalised. It will include representation from Marlborough District Council, Ministry for Primary Industries, key community and interest groups, iwi and New Zealand King Salmon.

Marlborough Mayor Alistair Sowman welcomed the constructive approach being taken by all parties in the search for solutions.

“The best practice guidelines were aimed at meeting the needs of the community and continuing to be a world leader in sustainable aquaculture. It’s vital we work alongside each other to ensure those guidelines can be met,” said Mr Sowman.

The working group’s recommendations will not be binding, but will inform future planning work for both the Marlborough District Council and central government.

Dietary interventions vs Statins

n 1952, the first informal explorative pilot studies on human diets took place in Italy, Japan, Spain and South Africa and those first data have been used in the experimental designing of the first phase (1958-1983) of the “Seven Countries Study” (SCS). The SCS suggested an association between serum cholesterol and cardiovascular diseases (CVDs).

However, this association was not consistent across the various cohorts of participants in different countries. The link was very clear in US and Northern European cohorts but it was rather weak in Southern European and Japanese cohorts. Nevertheless, the SCS triggered research into cholesterol-lowering drug strategies, ultimately leading to the development of statins amongst others.

The clinical evidence in support of statins is strong but statins aim to lower serum LDL-cholesterol whereas the SCS has shown that people with high serum cholesterol do not necessarily face increased cardiovascular risk!

So, today, the vast majority of the medical community advocate (unfortunately!) these drugs as highly effective first-line therapeutics in primary and secondary prevention of CVDs without considering the human’s diet habits or blood data (i.e. if they follow the Mediterranean diet guidelines or what are the blood levels of HDL-cholesterol – the good cholesterol).

There is constantly growing evidence of side-effects associated with statins in a significant proportion of patients suggesting that these drugs are not a universal solution to CVDs! We need, therefore, to revisit the evidence and to re-appraise the relative importance of cholesterol amongst many other lipids as potential modulators of atherogenesis.

Do all people need statins or actually statins make things worse?

What are the relative merits of statin therapy?

How can dietary interventions that impact on lipids other than cholesterol, including omega-3 fatty acids and polar lipid fractions of various foods (e.g. fish), help in our attempt to decrease cardiovascular risk?

We suggest that careful design around the lipid components of dietary interventions presents a credible alternative in patients who are intolerant to statins or averse to taking such drugs.

Pictured: CEO of BioMar, Carlos Diaz

BioMar launches global strategy

T

he BioMar Group launched on June 1, 2016 a new global strategy “Shaping the Future”.

The strategy will reinforce BioMar’s position as a locally responsive, agile, and specialised aquaculture feed provider.

Earlier this year BioMar launched a renewed purpose statement “We are innovators dedicated to an efficient and sustainable global aquaculture” and a new corporate theme “Let’s Innovate Aquaculture”. Now follows a new corporate strategy. “It has been important for us to create a strategy built on our corporate DNA and in particular on the four pillars supporting our purpose statement: Innovation, Performance, Sustainability, and Cooperation”, explains the CEO of BioMar Carlos Diaz.

Carlos Diaz underlines that it is the perfect time for launching a new strategy: “We have seen strong financial results in the last couple of years; we have achieved many of our strategic goals; and both we and our owners Schouw & Co. are willing and capable to invest further to continue the success.”

The new strategy targets a 6 percent EBIT level combined with a 50 percent increase in BioMar volumes over the next five years coming from both organic growth and acquisitions.

The development of the new strategy has to a large extent involved stakeholders from within and outside BioMar: “We have in particular

listened carefully to our customers.

It has been crucial for us to both address their present areas of concern and create a strategy that fits with their future plans. Closeness and cooperation with our customers is fundamental for our and their success.

One of our new initiatives is that we want to exploit and develop our agility and flexibility further to the benefit of our customers.”

A first step in the strategy is strengthening some of the core functions in BioMar. “We have a very lean, agile, and locally responsive organisation. However, in order to secure future growth we want to further enhance our global innovation capability, some of our corporate support functions, and in general our capacity to enter new markets and feed more species”, explains Carlos Diaz.

As one of the first initiatives BioMar will adjust the operating model and establish three market divisions; Salmon, Emerging Markets, and EMEA. “Our new Salmon Division will comprise all current salmon markets.

We target to improve efficiency and integration between these markets and not least to reinforce our R&D efforts in a specie, which accounts for the major share of our turnover, and which at the same time is extremely important for the development of new solutions for the whole aquaculture industry.”

The new Emerging Markets Division will in the beginning be small, in terms of turnover, but Carlos Diaz sees this new division as one of the most important initiatives to secure growth

for BioMar: “We are currently building a plant in China and we see great opportunities in China, in other Asian markets, and in Latin America. To really tap into these opportunities we need to have a stronger coordination and link between business units and more implementation power.”

BioMar’s third market division will be the EMEA Division, covering Continental Europe, the Middle East, and Africa. It is the continuation of BioMar’s previous Continental Europe market region. “This week production is starting in our new plant in Turkey, we have seen major improvements in the situation in Greece, and the region has in general performed well. With the new steps we want to consolidate and strengthen our market position in this important area”, concludes Carlos Diaz.

New executive structure

The BioMar Group presents a new executive team in continuation of the launch of their new corporate strategy, ‘Shaping the Future’.

The new Executive Committee will consist of Carlos Diaz, CEO, Mogens Stentebjerg, CFO, and three Vice Presidents: Jan Sverre Røsstad, Ole Christensen, and Henrik Aarestrup.

“I am very confident that the new team will enable us to strengthen our position as a locally responsive, agile, and specialised aquaculture feed provider. It will consist of highly skilled executives with a strong management background, a solid understanding of the aquaculture business, and complementary profiles, Carlos Diaz says.

Carlos Diaz will during an interim

period personally take the lead of the Salmon Division, however Jan Sverre Røsstad, BioMar’s current Vice President for the North Sea region will immediately become more involved in BioMar’s Chilean operations in order to start creating a stronger link between BioMar’s two largest market areas in Chile and around the North Sea. Ole Christensen will head the new EMEA Division, which will succeed BioMar’s current Continental Europe region where he was also at the helm. Previous to that Ole Christensen headed R&D for BioMar Continental Europe and he has a very broad experience covering all aspects of the feed business from sourcing and product development to commercial management.

Henrik Aarestrup will move from the position as Global Marketing Director for BioMar to the position as Vice President for BioMar’s Emerging Markets Division.

Henrik Aarestrup has, besides his function at the head of marketing, been deeply involved in the development of business plans and strategies for several BioMar companies around the world.

With a strong knowledge of the entire BioMar organisation combined with a long experience in international management his role will be to link the emerging markets to the rest of the organisation.

Mogens Stentebjerg, BioMar’s long-time CFO, continues in the Executive Committee.

here are three 303 different species cultured in the aquaculture in contrast to the whole livestock industry where the number of cultured animal species is only eighteen. Out of the total three hundred and three, there are two hundred and ten finfish species and thirty crustacean species farmed. Each individual species has different culture conditions and biological needs as well as nutritional requirements and feeding behaviours.

As a result, the amount of research and customised applications for each one in aquaculture is multiple compared to livestock. In addition to the vast variation among aquatic species (from crustacean to marine carnivorous fish and fresh water filter feeder fish), the aquatic environment where the species live contribute to an even bigger challenges to the farmers and feed manufacturers.

A typical example is the shrimp industry, where the animals have slow feeding behaviour. Being external masticators they nibble their feed patiently which results in a prolonged residence time of the feed pellets in the water.

Consequently the nutrients that are present in the feeds are being leached out of the pellets or dissolved in the water. This is considered as one for the main issues of the industry because the consumed and utilised nutrient intake does not meet the intended levels provided from the feed to meet the species requirements.

Such imbalanced diets that do not meet the species requirements can negatively affect the growth performance of the shrimp as well as many other parameters, depending on the deficient nutrients.

In addition, the leaching of nutrients including nitrogen compounds like supplemental amino acids, can negatively impact the water quality, leading to eutrophication with an undesirable impact to the environment.

A recent advance in that area is the newly launched methionine source which is the first dipeptide (DL-Methionyl-DLMethionine) specially designed for the shrimp industry and the unique feeding behaviour as well as digestive system

of crustacean. As methionine is in most cases the first limiting amino acid, this product’s specialisation aimed to address the particular challenges previously described.

The main characteristic features of the dipeptide are the mixture of four different Met stereoisomers (DL-Met-Met, LDMet-Met, DD-Met-Met and LL-MetMet) and the significantly reduced water solubility. As a result, the clear benefits of the product to the industry are a more sustain release, as the four different stereoisomers are gradually digested in the gut of the shrimp and a lower leaching of the supplemented methionine from the pellets, compared to the other commercial methionine sources available in the market.

With more tangible application, this novel methionine dipeptide can replace (as is about 200 percent more efficient) the most widely used commercial methionine source, DL-Methionine for Aquaculture, while supplementing with half the amount the shrimp maintain the same growth performance.

Over the years solutions customised to individual species needs came from various disciplines of the value chain of aquaculture production. Significant improvements on the feed manufacturing and processing, farming practices, genetic selection, health solutions and of course nutrition, contributed to the growth of the industry and made it a more viable, attractive and profitable sector.

The way forward is investing on understanding the needs/challenges of each species and emphasising on apply this knowledge and technological advances to specialised solutions to help the growth of each specific industry, sustainably.

Innovative approach to ultrasound could increase salmon harvest volumes

T

he Scottish Aquaculture Innovation Centre (SAIC) has launched the first of its Rapid Response projects with an initiative that will explore the potential of a novel approach to ultrasound to delouse farmed salmon and, ultimately, increase harvest volumes.

The six-month project brings together industry partner Pulcea with academic partners from the University of Dundee and the Institute of Aquaculture at the University of Stirling to research the efficacy of ultrasound in targeting and dislodging

naturally occurring sea lice in a noninvasive and non-harmful way.

Says Heather Jones, CEO of the Scottish Aquaculture Innovation Centre (SAIC): “This innovative new project is precisely the kind of initiative that our Rapid Response scheme was set up to support. It is small-scale at this stage but, if successful, could have a significant positive impact on the aquaculture industry not just in Scotland but around the world.”

Awarded grant funding of UK£39,467 by SAIC, the project seeks to quickly determine the ability of ultrasound to delouse salmon in a way that neither harms the host fish nor the environment.

Explains Dr Paul Campbell, Reader of Physics at University of Dundee: “We’re taking a technique that’s

Nutreco acquires South African premix and feed additive company Advit

utreco has entered into an agreement to acquire Advit, a South African premix and feed additive company. Advit is headquartered in Johannesburg and produces a wide range of premixes, farm minerals and animal health products. Trouw Nutrition, Nutreco’s animal nutrition business, entered a strategic alliance with Advit in 2015. The acquisition is subject to regulatory

proven successful in human medicine and we’re carefully re-engineering it to explore its effectiveness in advancing fish health.”

If the preliminary results are positive, the industry-academia partnership intends to upscale the ultrasound-based treatment to a comprehensive marine engineering solution with global reach.

Maximising harvest volumes is just one of the anticipated outcomes of the project. Comments Ian Armstrong, Managing Director of Pulcea: “As we progress further into our research, we hope to make a number of other discoveries that will benefit fish health and welfare. These, in turn, could help to unlock the industry’s growth potential and deliver real economic benefit to Scottish aquaculture and beyond.”

approval and is expected to close in the second half of 2016.

South Africa is the largest and most advanced animal nutrition market in Africa. Advit has a solid market position for all livestock species. It operates country-wide and also exports to neighbouring countries.

Nutreco entered Africa in 2001 by acquiring a share of the Egyptian company Hendrix Misr, which came under full ownership in 2013 and was renamed Skretting Egypt.

Nutreco increased its presence in 2014 through a fish feed joint venture in Nigeria. Earlier this year it announced a fish feed joint venture in Zambia.

n 2015 Nutreco reported higher financial results with net revenues of €5.7 billion (2014: €5.3 billion) and an operating result of €282 million (2014: €236 million). Results improved in all of Nutreco’s segments: Animal Nutrition, Aquafeed and Nutreco Iberia.

Nutreco made steady progress against its sustainability objectives. It further strengthened its supply chain through supplier audits, and embedded sustainability key performance indicators into its business reporting model.

The 2015 annual review was drafted according to the fourth generation of the Global Reporting Initiative guidelines.

“2015 was in many ways a special year for Nutreco.

The financial results were very good across all of our businesses. This confirms that we are increasingly successful in translating our R&D and innovation capabilities into sustainable nutritional solutions valued by our customers. With the acquisition of US-based trace mineral producer Micronutrients we realised the thirdlargest acquisition in our history, making Nutreco the category leader in a specific feed additive segment,” said Knut Nesse, CEO of Nutreco.

“In June we organised our 8th AgriVision conference in the Netherlands, with close to 400 participants from over 40 countries. But perhaps the most visible event was the delisting of Nutreco from the Amsterdam stock exchange as a result of the take-over by SHV. We opened a new chapter for Nutreco as a private company, while continuing our ‘Driving sustainable growth’ strategy with the full support of our new shareholder.”

What to expect?

The good financial performance in all of Nutreco’s three segments was mainly the result of a more favourable product mix and the contribution of Nutreco’s acquisitions in Brazil, as well as positive currency effects.

Animal Nutrition, primarily trading under the Trouw Nutrition company brand, performed well despite difficult market circumstances in the global swine and dairy sectors. The increased focus on global products improved the performance of the Selko feed additives brand.

In Aquafeed, trading under the Skretting company brand, the salmon feed business performed strongly in 2015, and maintained its position as global market leader, although there is still overcapacity in the main Norwegian market. In shrimp feed, Ecuador reported strong organic growth.

Nutreco’s Iberian business performed well on the back of a recovering Spanish economy. Nanta, a producer of compound feed, reported growing volumes to third-parties, while Sada, which specialises in poultry meat, benefited from good performance during the high (summer) season.

The DTG2 ROV The DTG2 is operated by a hand-held controller

Aqua-Cage Fisheries uses Deep Trekker DTG2 ROV in rainbow trout farming operations

A

qua-Cage Fisheries is an aquaculture farm in Parry Sound, Ontario that produces rainbow trout for the food market. They receive fingerlings from a hatchery in Southern Ontario, grow the fish in the open waters of Georgian Bay and harvest them for a processor that ships to major grocery stores. Aqua-Cage produces environmentally sustainable, high quality fish for the consumer, while bringing in a profit.

Last year, Aqua-cage Fisheries acquired a Deep Trekker remotely operated vehicle (ROV) to perform a multitude of jobs around the farm.

Deep Trekker Inc. manufactures completely portable ROVs for underwater inspection purposes in a number of industries. Due to the complete portability, robust design and ease-of-use that Deep Trekker products offer, the aquaculture industry has become the perfect place for the ROVs to operate. Having a tool that farm managers and employees can easily deploy below the surface in less than a minute for inspection and routine tasks has brought about numerous benefits to farms around the globe.

Aqua-Cage Fisheries has been using their Deep Trekker DTG2 ROV for the past year to accomplish subsurface inspections from a safe top-side environment, to inspect the nets for holes, to monitor fish behaviour and health, to inspect mooring lines and anchors, and to check cage depths to ensure they are not touching the lakebed.

Aqua-Cage Fisheries does not employ commercial divers to perform underwater inspection work. The ROV performs the necessary tasks while eliminating all of the risks associated with sending a person into the water.

“Before Deep Trekker we had another company’s unit… two units in fact. We needed two because while one was away for necessary repairs/maintenance, we could not afford downtime and a second unit was essential to get us through that month or two (hoping it didn’t develop issues as well). We’ve only needed one Deep Trekker even though it is less expensive than the other company’s submersible,” Kana Upton from Aqua-Cage Fisheries explained when asked about how they went about performing tasks before they had a Deep Trekker ROV. When asked to comment further on the difference between their current Deep Trekker DTG2 ROV and their

previous units, Aqua-Cage Fisheries explained that the fact that the DTG2 has batteries housed within the submersible unit is a major plus for them. They state that it cuts down the set-up time and reduces the equipment required to run the unit.

“With the other units we had, I would need to bring an inverter/generator, fuel, a TV (as the screen was too small), an extension cord, the unit’s box, the controller box, and all necessary connection cables. With the Deep Trekker I wheel one box around. The unit requires maybe 20 seconds to get in the water. The best part for me is not having the constant sounds and exhaust fumes from the inverter. The Deep Trekker is completely silent topside. Plus it’s fast in the water! Really fast!” says Kana.

The fact that Deep Trekker ROVs are entirely portable is widely appreciated in the aquaculture industry. Even though farms may be quite large in size, the DTG2 ROV is the perfect option for performing multiple underwater inspections at several locations. Deep Trekker’s on-board batteries completely eliminate the risk of generator fuel leaks and spillage that can be detrimental to any farm.

Deep Trekker also offers a number of add-ons and accessories that can improve the unit to suit specific jobs and tasks. Aqua-Cage Fisheries recently upgraded their ROV to include a side facing auxiliary camera that will make net inspections with the ROV even easier.

“I can’t say enough about the customer service we have received. Having the owner of the company make visits to demo, and again to try out new features has been invaluable. They work diligently to solve industry problems and come up with effective solutions. Deep Trekker is an obvious addition to any underwater work.

It’s cheaper, safer and often more functional than divers, and it’s cheaper, more dependable, better service and more functional than the competitor,” said Kana and Gord Cole, co-owner of Aqua-Cage Fisheries.

Aqua-Cage Fisheries will continue to utilise their DTG2 ROV to perform all sub-surface inspections on the farm and monitor the fish stock. http://www.deeptrekker.com/

Court of Appeals orders Sernapesca to provide information about antibiotics used in the salmon farming industry

O

n Tuesday, the Court of Appeals of Santiago accepted the claim submitted by marine conservation organisation Oceana, and ordered the National Fisheries and Aquaculture Service of Chile (Sernapesca) to publish the information –disaggregated by company– requested by Oceana, concerning antibiotic use by the salmon industry in Chile in 2014. This claim was filed after 37 companies, and subsequently Sernapesca and the Council for Transparency, refused to disclose such data on the grounds of “competitive and business risk” for the companies. The Court’s ruling qualifies as “illegal” the prior resolution issued by the Council for Transparency.

“We welcome this extensive 38page resolution whereby the Court of Appeals questions the inexplicable determinations by the Council for Transparency, Sernapesca and 37 salmon farming companies to refuse to disclose public interest information such as the amount of antibiotics used by each company, even though six companies agreed to the request. We expect for this categorical ruling to set a precedent, that salmon farms comply with it and that once and for all, the use of antibiotics in Chilean salmon farming can be made transparent”, said Liesbeth van der Meer, interim

executive director of Oceana.

The resolution by the Court of Appeals states that “this Court cannot but notice the fact that the Council for Transparency decides to keep certain secret niches within a system where publicity is the rule and secrecy the exception; and this regarding certain data of the companies of the said industry –which are under the control of state agencies to which they should submit all such data and background information required for their adequate enforcement– particularly considering that these companies produce fish for human consumption, upon which not only the aforementioned control is required –specifically by Sernapesca– but also, as valid and as relevant, social control, so that citizens are able to know how the species they purchase and consume have been produced.”

Furthermore, the ruling states that “the information required [by Oceana] strongly compromises public interest and therefore, its disclosure should prevail over any other interest by companies refusing such disclosure.”

This ruling follows the information request made in 2015 by Oceana concerning disaggregated data on antimicrobials used by salmon farms in 2014.

There is a simultaneous constitutional unenforceability

Increased demand for QRILL™ products worldwide

A

ccording to the company’s latest Annual Report, 2015 was considered a historic year for Aker BioMarine, the leading supplier of krill-derived products to the consumer health and wellness and animal nutrition markets.

Aker BioMarine generated USD 105 million in revenue in 2015, which yielded an EBITDA of USD 25.7 million.

QRILL™ Aqua, the Antarctic krill meal used in feeds for shrimp, marine fish and salmonids grew in revenues from USD 39.2 million in 2014 to USD 44.9 million in 2015.

Since 2012, QRILL™ Aqua revenues have grown by 105 percent.

Sustainable harvest has been at the core of how Aker BioMarine conducts business. In 2015, Aker BioMarine was recognised several times for its sustainability achievements:

requirement filed before the Constitutional Court filed by Multiexport and other 22 salmon companies aimed at preventing the disclosure of information on antibiotic use broken-down by company between 2009 and 2013.

This battle began in July 2014 when Oceana submitted a complaint before the Council for Transparency, after Sernapesca refused to reveal the amount and type of antibiotics used by 58 salmon farms operating in Chile. This, following the resistance by 50 salmon farms on the grounds that they would face “competitive and business risk” if they disclosed the required information. At the time, the Council for Transparency also ruled to the benefit of the salmon companies, stating that Sernapesca was not required to disclose disaggregated figures except in special cases.

Subsequently, the Court of Appeals of Santiago accepted the claim filed by Oceana; however, Multiexport submitted a constitutional unenforceability complaint which has still not been addressed by the Constitutional Court.

“We expect this ruling to become a precedent for the other ongoing proceeding. We make a call to the Constitutional Court to reject the unenforceability requirement filed by the salmon farms, putting an end to this lack of transparency and giving citizens something as basic as access to public interest information directly related to health and the environment”, concluded van der Meer.

• In 2015, Aker BioMarine strengthened its partnership with the World Wide Fund for Nature (WWF-Australia) to bring it closer to activities in the Southern Ocean • Aker BioMarine, along with several NGOs established the Antarctic Wildlife Research Fund (AWR) to facilitate and promote more research on the Antarctic ecosystem • The Marine Stewardship Council (MSC) renewed Aker BioMarine’s sustainable krill harvesting certification for another five-year period (2015-2020) • The Sustainable Fisheries Partnership (SFP) gave Aker BioMarine’s fishery an ‘A’ rating in the 2015 Reduction Fisheries Sustainability Overview • Nutrition Business Journal’s January 2015 edition featured Aker BioMarine as the winner of its Business Achievement Award in the category of Sustainability, making it the first omega-3 company to receive this award "Wellbeing of our oceans and planet and to ensure the future of our business,” Mr Nordrum says.

ollowing its success with huge orders from earlier, GRAINTEC has secured a large design and supply order for a new fish feed factory. The company Marine Harvest Scotland Ltd. is going to build Europe´s most modern salmon feed plant - a high technology factory on the Isle of Skye, where Denmark-based Graintec A/S stands for the project design.

The new factory is going to produce 170,000 tons a year.

With a total contract value of about 33,5 million Euro, the project is the second largest order in Graintec’s history.

High technology is going to play a central role and with the current trend for sustainability and organic food, the factory will meet many different demands. Fish feed for different sized salmon can be produced (both starter and grower fish) and there will be organic feed production. The technology that is implemented by Graintec will include a new solution for grinding and will focus on energy recovery, which is one of the areas the Danish company with subsidiaries on several continents has specialised in.

“We are world leaders with regard to the production process of salmon food, meaning that there is a 67 percent chance that the salmon you buy in the store has been fed with food from a production plant where Graintec in one way or other has been involved in”, says CEO Niels Pedersen. “We did it again, and look forward to extend our good collaboration and the works on the Kyleakin project”, he says proudly, referring to 2012, where Graintec received its biggest design order, a feed factory for the Norwegian Marine Harvest ASA with a contract sum of about 36 million Euro.

Graintec has specialised in eco-friendly production facilities for extruded fish feed and pet food. The company executes projects, designs and installs production plants, and acts further as consultants in the field. Efficiency and responsibility for the environment, as well as hygiene and research within the field are key matters for Graintec. Due to a focused and customer-oriented approach, Graintec has been able to triple the yearly turnover to an average 39 million Euro over a three-year period.

The state-of-the-art feed plant placed in Kyleakin, on the Scottish Isle of Skye, is going to produce feed for Scotland and other Marine Harvest sites in the North Atlantic region.

Further development on the site is depending on the coming construction permits. Planning permission is expected later this year and commercial production will start in summer 2018.

OTAQ – A SealFENCE system is installed in a site near Portree

Underwater Acoustic Innovation wins top prize at Scottish Edge Awards

O

TAQ, a company designing and manufacturing technology for the global fish farming industry, has been announced as one of the biggest winners of the Scottish Edge awards, with a prize of UK£100,000.

The competition, aimed at identifying and supporting Scotland’s up-and-coming, innovative and entrepreneurial talent invited OTAQ to pitch at the finals of the event in Edinburgh this week where over UK£1.27million in grants and loans was awarded.

The Oban based firm scooped UK£100,000 after Commercial Director Chris Hyde led the firm’s pitch on their launch product, an innovative deterrent system called SealFENCE which uses unique underwater acoustic technology to prevent seals from attacking marine fish farming sites.

Seal and sea lion attacks currently cost the fish farming industry over US$1 billion dollars a year worldwide as seals attack marine salmon farms for food, especially in the winter months. OTAQ’s innovative system provide a solution to the growing problem.

From 239 original applicants, just 22 of Scotland’s most promising entrepreneurs were invited to pitch their businesses to an expert panel of judges in order to win up to UK£100,000 each in grant funding and loans. Just 15 of the start-up and growth stage businesses were successful with only OTAQ and two others awarded the full amount applied for.

Chris Hyde, commercial director, OTAQ, said: “This award is going to make a major difference to our company and will mean that we can accelerate our export plans significantly, introduce our product to more markets and recruit more staff this year.

“Our company vision is to become world leaders in aquaculture technology and specifically in acoustic products such as predator control and monitoring systems.

Our key area of expertise lies within underwater acoustics and sonar and we intend to build a reputation as experts in

this field within our industry.

Evelyn McDonald, CEO of Scottish EDGE, remarked on OTAQ’s achievement: “We’re absolutely delighted to be able to support OTAQ as part of our eighth competition round. Our panel of expert judges were impressed with the high standard of Chris’ pitch and see great potential in OTAQ’s product. We look forward to supporting the business as they develop and to welcoming them into our network of high-profile alumni.”

Sir Tom Hunter, renowned Scottish entrepreneur and philanthropist, said: “100 percent of the net new jobs in the UK will come from businesses less than five years old – the winners at Scottish Edge are the job creators of today… We need to invest in them and nurture them in any way we can to build our economy and to provide the quality jobs our people deserve. We need to build a far greater pipeline of high growth businesses if Scotland is to succeed, Scottish Edge is one critical element of that pipeline and I commend all the entrants – not winners yet – and the winners for their commitment to building great entrepreneurial businesses.”

Chris Hyde of OTAQ, added: “The entire Scottish Edge experience has been invaluable. The process and feedback from the judges has really makes us focus on our business and how best to communicate what it does; this has put us in very strong position for achieving our vision.”

by Johan Den Hartog, Managing Director of GMP+ International

n the last decade, the aquaculture industry has grown exponentially; with this growth is expected to continue. Consumers appreciate this growth because of the positive connotations that go along with eating fish.

Because of the healthy image of fish and other aquatic produce, it is important to assure the safety of the aquatic animal products. Water quality certainly has an impact, but also the quality of aquafeed. A proper control of the safety of aqua feed can add value to the quality of the aquatic animal products.

Feed safety risks can have a direct influence on the performance of aqua culture and indirectly on the access of (new) markets of aquatic produce worldwide.

In this article, we give an overview of possible feed safety risks and the way of control them in a transparent way and according international standards. We make also remarks about sustainability aspects of aqua feeds.

Feed safety hazards

Practice tells us that feed ingredients can be contaminated with chemical and physical substances, as well as biological agents. It can depend on the ingredients used and the origin and production processes of these ingredients and the aqua feed as such.

Chemical hazards may occur through natural chemicals (such as mycotoxins), industrial and environmental contaminants (like heavy metals, dioxins, and PCB’s) and residues of veterinary drugs, pesticides, and radionuclides. Physical hazards are foreign objects like pieces of glass, metal, plastic, or wood. Biological hazards are contaminants such as bacteria, viruses, fungi, and parasites.

In aquaculture, too much contamination could influence the growth performance of the aquatic animals, thus increasing the feed conversion, whilst also inducing disease resistance; which in turn results in biological changes. These are all consequences with an economic impact.

More importantly however, contaminants transferred from feed into the aquatic animal can also have a negative impact on the

safety of the aquatic animal products for the consumers and on the health image of it.

It is clear that safe aqua feed is essential for aqua culture, not only for a profitable production of the aquatic animal products, but also for for the sake of undisturbed and continued sales into the market; especially export markets. Moreover the consumers expect a healthy product.

To get safe aqua feed, a proper feed safety control by means of an adequate assurance system is a precondition. If such an assurance system is applied demonstrably, it will add value to the aquatic animal products definitively.

Essential elements in a feed safety assurance system

For the application of proper feed safety control, a series of risk mitigation measures should be put in place to achieve the best possible result.

First of all, it is necessary to implement a proper prerequisite program. It is about maintenance of buildings and machinery, training of employees, hygiene and cleaning program, pest control, etc. This all creates a basic level of control of possible hazards in the production process.

Secondly, HACCP (Hazard Analysis and Critical Control Points) is a tool to identify specific hazards, which could become risks in the production process, remained after application of the prerequisites.

This will result in identifying the real risks in the production process and in taking proper control measures, as well as monitoring of the effectiveness of these control measures. Any change in the production process should be implemented after renewing the hazard analysis for identifying new risks and adjusting control measures.

Additionally to HACCP, a proper quality management system ensures the consistent application of the defined control measures and verification procedures.

GMP+ Feed Safety Assurance

The control measures previously mentioned are well known elements in many quality systems. They are all integrated in the

20 | July | August 2016 - International Aquafeed

FEATURE

GMP+ Feed Safety Assurance (FSA) certification. Based on longstanding practical experiences of many participants collected in the past 25 years, GMP+ International added some other essential elements into the GMP+ FSA certification scheme: chain approach, traceability, and early warning.

Practical experiences show that often the source of contamination in the feed sector occurs in the supply chain. In the past, some cases resulted in delivery of huge amounts of contaminated feed ingredients downstream, resulting in much media attention and high cost for removal. Therefore, in 1999 was decided to extend the scope of the GMP+ FSA certification to the whole supply chain.

Chain approach is a basic principle in the GMP+ certification scheme and it means that all companies in the supply chain take their responsibility regarding the control of the feed safety of the products they deliver or services they provide. It is the most effective approach to mitigate emerging risks in the chain as early as possible instead of an uncontrollable end-of-pipeline approach. Only in some cases, a gatekeeper option is allowed for the producers of pre-mixtures and mixed feed. GMP+ Feed Certification scheme is unique in the world about this chain approach principle and therefore appreciated by many mixed feed producers.

All measures mentioned before are focused on avoiding preventive to avoid contamination of feed products put on the market, so preventive. Traceability and EWS are corrective measures to trace back contaminated feed products is delivered into the market. It enables tracing back to find the source of the contaminated lot(s) and if possible to find out the cause, what which can contribute to improved control in the supply chain in the future.

Traceability also enables also tracing forward to trace customers who received (possibly) contaminated lots in order to block these lots and avoids further distribution of the contaminated feed.

Practise shows that this approach is very effective and avoids incidents at a larger scale with image and financial damages.

Finally, EWS is an extra safety net. In case a GMP+ FSA certified company exceeds the maximum permitted level of a contaminant in feed products, he is obliged to notify GMP+ International. When other companies can be confronted with the same contamination in purchased feed materials, GMP+ International will send a EWS message to all GMP+ FSA certified companies in order to alert them. This contributes to minimize the impact of contaminated lots of feed product on the market.

Participation in GMP+ FSA certification

Currently, over 15,100 companies / locations are GMP+ FSA certified, located in almost 80 countries all over the world. All kind of companies are involved: collection, trade, producers and processors of feed materials, transports, charters, producers of additives, pre-mixtures and compound feed, including aqua feed.

In this respect, GMP+ FSA certification is leading globally.

This global presence and acceptance of GMP+ FSA is a real opportunity for the aqua culture to add value to its aquatic animal products, when it should be produced by aqua feed produced under GMP+ FSA certification.

Aqua feed sustainability

There is a growing interest for sustainability issues, besides food safety, in the production of aquatic produces. Evidently, the attention for sustainability of aqua feed is growing. That is not limited to the production of aqua feed as such, but also about the used ingredients in aqua feed. It is about social and

Figure 1: EWS* notifications by feed product Source: GMP+ International * EWS = Early Warning System

environmental issues.

Social issues are for instance fair payment of employees, proper working conditions and reasonable working hours.

Environmental issues are for instance about responsible fish catch (for production of fishmeal), responsible production of soy (Avoiding deforestation of the Amazon forest) and palm oil (ecological diversification).

A real advance for GMP+ FSA certified producers of aqua feed is that certification of sustainability issues easily can be combined. End 2014, GMP+ International introduced the GMP+ Feed Responsibility Assurance module. The structure and principles are the same as of the GMP+ Feed Safety Assurance module. In this way, GMP+ International offers a ‘one stop shop – multiple certification’ solution to feed companies, saving a lot of money.

Another advantage is that it covers the whole feed supply chain (chain of custody), so it links the demand in livestock and aqua farming with the primary production (cultivation, marine sourcing, mining, etc.) of the ingredients. A third advantage is the international coverage the GMP+ certification scheme, with a strong international network and involvement of stakeholders.

The current focus of GMP+ FRA is the use of responsible soy for the production of dairy feed, pig and poultry feed. GMP+ International is considering to extend the scope of GMP+ FRA to more feed ingredients (upstream) as well as to aqua feeds (downstream). These extension will be developed in close cooperation with and consultation of market initiatives in the animal production and in alignment with running initiatives in the aquatic sector.

Fueling the fire within DIGESTIBLE ENERGY DEMANDS BY FISH

D

ietary energy intake is the factor that largely dictates the dietary concentrations required for all essential nutrients (Figure 1). The energy density of the feed has been shown to directly influence the amount of feed consumed across a wide range of species (Dumas et al., 2010; Glencross et al., 2008).

With more energy dense diets, a reduction in the amount of food eaten is usually observed and this has direct implications on the concentration of essential nutrients required in any daily intake to satisfy daily nutrient demands and as such the animal’s growth demands. Because of this link between energy and intake it also has the clear effect of being a key factor in influencing the feed conversion ratio (feed/gain) of fish to which those diets are fed (Figure 2).

The energetic content of the three macro-nutrient classes; protein (23.6 kJ/g), lipids (38.5 kJ/g) and carbohydrates (17.3 kJ/g) is the source of this dietary energy, although the capacity of different fish species to utilise each of these nutrients varies according to trophic level (Enes et al., 2009; Saravanan et al., 2012; Schrama et al., 2012; Glencross et al., 2014). In species like tilapia, dietary energy demands can be met through the metabolism of dietary protein and lipid intake, like carnivorous species, but also through the digestion and metabolism of starch (Bureau et al., 2002). However, in carnivorous species, like Asian seabass, starch is not only poorly digested, but it has also been shown that the animal poorly metabolises the energy from this macronutrient, preferring to rely on protein and lipid as energy sources (Glencross et al., 2014).

maintenance also includes that energy utilised through activity and heat loss. Being a poikilothermic animal, the energy demand by fish will directly reflect the temperature of its environment.

However, both above and below critical thermal ranges there is a deterioration in the nature of

Figure 1. The relationship between energy demand, feed intake and dietary nutrient demands.

Defining Energy Demands

Dietary energy demand is generally assumed to be the sum of the requirements of a growing fish for its maintenance and growth energy needs (Figure 3). Energy demand for

this relationship between temperature and energy demand. This also influences the efficiency with which dietary energy is utilised (Glencross and Bermudes, 2011).

Energy demand for maintenance by all fish is a mass-specific relationship. Therefore, to understand the relationship between a fish’s live-weight and its energy demand, an equation needs to be established. Typically these relationships are described by an allometric equation such as y = axb. In this relationship the exponent b describes the relationship between the animal’s liveweight and its energy demand for maintenance (often referred to

as the metabolic body weight exponent), while the coefficient a describes the species and temperature specific nature of that energy demand (White, 2011).

Energy utilised by fish for maintenance metabolic activities can be estimated using several methods. Both direct and indirect calorimetry has been used to examine the energetics of fish whilst being fasted. The rate of this energy utilisation is referred to as the standard metabolic rate (SMR). Direct calorimetry uses the assessment of the loss of somatic energy reserves from starved fish over a period of time (Figure 4). Indirect calorimetry typically bases its assessment of energy use on the measurement of an indirect indicator of energy consumption such as oxygen use or carbon dioxide production by starved fish.

The relationship between fish’s energy metabolism and its body weight (BW) conform to the allometric equation: a • BWb (White, 2010). Comparison of the energy metabolism exponent across a range of species shows a general exponent value of around BW0.80. Tilapia (BW0.833) Pangasius catfish (BW0.80), Asian seabass (BW0.80), grouper (BW0.79), Gilthead seabream (BW0.82) and European seabass (BW0.80) (Lupatsch et al., 2003; Glencross, 2009; Glencross et al., 2011; Trung et al., 2011; Glencross and Bermudes, 2012), has shown that the fundamental energetic constants such as exponents of metabolic body weight are very similar among a range of fish species, both omnivorous and carnivorous. As such, it is now generally accepted that a standard value for the metabolic body weight exponent of 0.80 (BW0.80) is applicable.

The maintenance energy requirement (HEm), as defined by the digestible energy consumption for zero net energy gain, this generally varies depending on temperature. At optimal temperatures a HEm value of ~40 kJ / kg0.80/d is typical for many fish species (Lupatsch et al., 2003; Glencross, 2009; Glencross and Bermudes, 2010; Glencross et al., 2011).

There is generally a linear effect of energy gain with increasing energy intake in most fish species. Though at higher energy intake levels this sometime appears as a curvilinear relationship (Lupatsch et al., 2003; Glencross, 2008; 2009). The slope of the regression line determined from energy gain against energy intake by fish is often termed the partial (or marginal) efficiency of energy utilisation and provides and guide to the efficiency of conversion (Figure 5). Because of the curvilinear nature of this response, near maintenance intake levels, this partial utilisation efficiency tends to be higher (up to 81 percent efficient), while at higher energy (>100 kJ/kg0.8/d) intake levels in some species this partial utilisation efficiency can deteriorate substantially and values as low as 15 percent efficient have been reported (Glencross et al., 2011).

Energy Demands for Growth

Energy demands for growth are dictated by a series of interrelated factors. These factors are; the amount of growth potential at a given water temperature and fish live-weight, the carcass composition (energy density) of that growth and the efficiency with which consumed and digested dietary energy is converted into that growth (Dumas et al., 2010; Glencross, 2012).

The estimates of growth potential are generally dependent on empirical data and clearly the most practical data for such an estimate is data from farm production operations. However, the limitations of health, genetics and sub-optimal environmental conditions need to be considered in such data sets.

The composition of whole fish over a live-weight range typical for that used in commercial production has been reported by several researchers (Lupatsch et al., 2003; Glencross et al., 2011; Trung et al., 2011; Glencross and Bermudes, 2012) (Figure

FEATURE

6). These data typically show an exponential relationship between live-weight and energy density of the fish. This relationship is reflective of the fact that lipid content of the carcass tends to follow an exponential relationship with size, while dry matter content (reciprocal of moisture content) generally reflects that of the lipid content, with lipid displacing water in the animal as it accretes in the carcass. By contrast protein content follows a linear function, with Figure 6. Variation in carcass composition of Asian seabass with varying live-weight size. Note how protein content is relatively stable around 17%, while lipid varies from less than 5% in small a typical protein content of the fish fish to over 10% in larger fish. Dry matter varies reflecting this difference in contributions to around 17 percent, with little effect of carcass gain between lipid and protein. Data derived from Glencross and Bermudes 2012. size on that protein content. Therefore, it can be noted that it is this adiposity of fish that drives this change in energy demands associated with the carcass composition.

Thirdly, is the conversion of dietary energy into that somatic energy. Among different fish species and intake levels the efficiency of energy conversion has been estimated to range from 0.44 to 0.81 (or 44 percent to 81percent efficient) (Glencross, 2008; Trung et al., 2011). Typical values tend to be closer to 0.66 across many species and issues of intake constraints and other methodological issues have been raised as influential factors (Schrama et al., 2012).

From the combination of growth potential, body composition, maintenance requirements and partial efficiencies of utilisation, it is possible to calculate the energy requirement at a range of fish sizes Figure 7. Iterative estimations for digestible protein: digestible and this is known as an iterative estimation of energy requirement energy demands for Atlantic salmon with varying live-weight.

It is also possible to define protein demands using a as would be applied for each size class of fish. similar strategy and therefore by bringing the two components together (energy demand and protein demand) possible to estimate the ideal protein: energy ratio at any fish size. Above this idealise line the diet is arguably over specification and the feed costs more than it needs to, whilst under this line the feed is under specification and the fish will deposit the excess energy as lipid and protein synthesis will be nutrient limited.

Measuring Digestible Energy

Measuring the digestible energy content of feeds is also an involved process and there are many studies Figure 8.

IN-SITU CLEANING Clean nets, but what about the fish?

A

A biofouling specialist gives us a concise overview of the problems involved

Malachi Stone from the International Aquafeed team talks to Björgólfur Hávarðsson MSc, about his presentation at Aquaculture UK

s some of our readers will know only too well, biofouling occurs when aquatic organisms colonise underwater structures such as nets used in aquaculture. Mussels, algae, hydroids and sea squirts will attach themselves to any available space, then grow and reproduce until the nets on your farm are

thoroughly clogged.

Fouling of nets in and of itself is problem enough, but it also brings additional issues. These miniature forests of algae and ascidians provide a refuge and gathering place for hordes of salmon lice and other noxious parasites, such as amoebas and bacteria - a source of physical misery for the fish and economic misery for the farmer.

At Aquaculture UK in Aviemore, Scotland, International Aquafeed had the opportunity to attend a talk on this very subject, given by Björgólfur Hávarðsson MSc from Steen-Hansen. His presentation, ‘In-situ cleaning: Clean nets, but what about the fish?’ gave listeners a great deal to think about.

Steen-Hansen is a privately owned Norwegian company established in 1932. The company initially focused on paints before turning its attention to the chemical impregnation of nets for aquaculture. By 1995 it was in all major aquaculture markets, and today it is a world leader in antifouling paints for the fishfarming industry.

The company now boasts its own production facilities, laboratories and R&D facilities. They had a turnover approaching US$20 million in 2014, and gross profits of more than US$350,000 the same year. They currently have 23 employees.

Their aquaculture products include NetCoating PLUS™, protecting nets from abrasion and UV damage, and AquaNet® antifouling, which can be adapted to different environments and net materials.

Steen-Hansen’s own specialists have also published a useful, informative, Net Care Certified booklet in collaboration with their partners, agents and cooperating universities. The Little Book on Fouling™ is non-commercial and available free of charge (order at www.bookonfouling.com). You can even order different versions, depending on where you are in the world. This makes great sense: the flora and fauna clogging nets in Chile - and the conditions they do it in - will probably be somewhat different from those in Scotland.

Even around the British Isles, Mr Hávarðsson says, the species involved, the intensity of accumulation and the length of the fouling season will all vary greatly, dictated by a combination of latitude and geography. It really does matter where you set up your farm.

Most of the organisms that colonise the nets have planktonic larval stages. As such, they are carried on the sea’s currents until they come into contact with a surface they are ready to settle on. Easy to see, then, why the currents around a fish farm will determine much about the annual intensity of fouling and the intensity within the site. This will lead to marked differences in the levels of fouling between one site and another.

Oceanic currents can thus be seen to greatly influence the establishment and size of the colonies of fouling organisms among which fish lice and other parasites love to hide. But they also influence the dispersal of the parasites themselves. Worse, in all this, the process may even be assisted by the farmer himself.

In-situ high pressure cleaning of nets is a widespread biofouling management tool in Norway. One effect of such cleaning is net abrasion, which usually manifests as greater or lesser degrees of expansion in the net fibres, or even holes. Spaces between the fibres make for an even safer haven for all kinds of parasites to hide in, and for hydroid colonies to take root. Subsequent cleaning cycles will leave the hydroid roots intact, ready to immediately start growing again - and quicker than before, as the cleaning has now removed all competing species. The cleaning

process also bursts the adult hydroids, releasing larvae in huge numbers. These spread locally, sink and adhere immediately to the first surface they encounter, thereby compounding the problem even further.

During in-situ cleaning, debris is dislodged and scattered, forming a cloud that spreads horizontally and vertically in and around the cage. Much of this debris is composed of fragments of hydroids, which float rather well and are packed full of stinging cells that cause inflammation in the fishes’ gills. Prolonged or repeated exposure can cause significant gill damage and perhaps even leave the way open for secondary infections.

Especially given that the debris cloud is also packed with harmful microorganisms: all fouling species have been found to harbour pathogenic amoebas, and many play host to virulent bacteria as well. In-situ high pressure cleaning also dislodges vast numbers of fish-louse larvae, which are then distributed elsewhere by

currents - as far as 160m away.

Owing to the interference of cages and fish, the localised currents at farming sites are erratic and will not always reflect the main currents in the area. It is therefore unrealistic to hope that these currents will disperse and neutralise the debris cloud before any real damage is done to the fish. In-situ cleaning in one cage will therefore affect other cages, and any given cage may be affected several times during a single cleaning cycle.

Furthermore, such cleaning cycles may need to be repeated within as little as 10 days.

Herein lies a terrible irony: in an attempt to clean his cages and thereby eradicate fouling and the ‘sink’ in which parasites accumulate, the farmer may actually be making a bad situation worse. The effect is rather like scratching a severe skin infection - temporary relief at the cost of greater problems in the longterm.

Currently, Mr Hávarðsson says, there is no truly satisfactory solution to these problems; it is more a case of employing wise practices in order to keep them at manageable levels.

For example, a farmer should use well-established methods to check his fishes’ gills for damage after in-situ net cleaning. If there is any, he would be best advised to wait a few days before using delousing chemicals. Hopefully by then the fishes’ gill membranes will be sufficiently recovered to be able to cope with such substances.

There is a desperate need for improved cleaning and antifouling devices. In the meantime, increased awareness of the problem coupled with sensible management techniques are the best weapons in the fish-farmer’s arsenal.

A VIEW ON AQUACULTURE DEVELOPMENT IN INDIA

I

by Dr B Laxmappa, Fisheries Development Officer, India

ndia is the second largest producer of fish in the world, contributing 5.68 per cent of global fish production. It is also a major producer of fish through aquaculture and ranks second in the world after China. India is an important producer of fish and shellfish through aquaculture globally, whilst also possessing a number of other flourishing sectors with vast resources and potential.

Aquaculture is the fastest growing food producing sector in the world with an annual growth of around seven per cent. India is the second largest producer of fish both in terms of production, and from aquaculture. Increasing demand for fish and fishery products would mostly be sourced from aquaculture and culture based captures fisheries in reservoirs as capture fisheries growth world over is stagnant.

Presently, the country ranks second in the world in total fish production with an annual fish production of about 10.07 million metric tonnes. As the second largest country in aquaculture production (Table: 1), the share of inland fisheries and aquaculture has gone up from 46 percent in the 1980s to over 85 percent in recent years in total fish production. The total aquaculture production of 4.64 million tonnes of which carp alone was responsible for the lions share (See Table 1).

India’s aquaculture production basically can be classified into freshwater, brackishwater and mariculture production. There are 429 Fish Farmers Development Agencies (FFDAs) and 39

Brackishwater Fish Farmers Development Agencies (BFDAs) besides huge number of Fishermen Cooperative Societies (FCS), private farmers for promoting freshwater and coastal aquaculture.

Some of the important species cultured in India are the Indian major carps, catfish, prawn and shrimp. Besides these, seabass, trout, tilapia fish culture, mud crab, clam and seaweed farming (Table: 2), are slowly gaining importance in the aquaculture scenario in the last few years as alternative livelihood supporting sectors as small-scale activities. Aquaculture in India has evolved as a viable commercial farming practice from the level of traditionally backyard activity over last three decades with considerable diversification in terms of species and systems, and has been showing an impressive annual growth rate of 6-7 percent. While the carp-based freshwater aquaculture contributing over 90 percent of the aquaculture production, thus Table 1: Top 5 aquaculture producers in 2010 Sl. No.

Freshwater aquaculture

Freshwater aquaculture showed an impressive ten-fold growth from 0.37 million tonnes in 1980 to 4.03 million tonnes in 2010, with a mean annual growth rate of over six percent. Freshwater aquaculture contributes to over 95 percent of the total aquaculture production. The freshwater aquaculture comprises of the culture of carp fishes, catfishes, tilapia, and prawns.

The three Indian major carps, namely catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala) contribute to the bulk of production by 70 to 75 percent of the total freshwater fish production, followed by silver carp, grass carp, common carp, catfishes and others forming a second important group contributing the balance of 25 to 30 percent.

It is estimated that only about 40 percent of the available area of 2.36 million hectares of ponds and tanks has put to use with an immense scope for expansion of area existed for freshwater aquaculture.

Induced breeding of carps and catfishes, hatcheries for massscale spawning, seed rearing and carp polyculture are some of the epoch-making technologies actually guided by the freshwater aquaculture development. The sector has also shown considerable diversification in recent years with the adoption of other species such as catfishes and freshwater prawns, due to their higher market demand and economic values.

Whilst production of 4–5 tonnes under carp polyculture is quite common, farmers of several regions are able to produce 8–12 tonnes/ha/year. Integrated fish farming with livestock and horticulture has not only been able to utilize the by- products/

wastes as principal inputs, but also made the farming practice highly remunerative and farmers’ friendly.

Pangasius sutchi, one of the swift growing catfishes was first introduced into India in the year 1995–1996 in the state of West Bengal from Thailand through Bangladesh. Initially farming was carried out in a limited area in the States of West Bengal and Andhra Pradesh.

This fish grows to 1–1.5 kg during one year, a minimum of 10–15 tonnes/ hectare/year is harvested through due to farming of this fish. There is a growing interest among the farming community in other states as well to take up Pangasius culture in a larger extent, thus paving way for demand for its seed and for establishment of commercial scale hatcheries.

Pangasius is being farmed under monoculture or polycuIture with carps. Recently in cage culture farming, about 3-5 tonnes production achieved with floating pellet feed in 10 months just from one cage (96 m3) in certain reservoirs of India. The

In addition to carp and catfish varieties, successful breeding and larval rearing of the giant river prawn (Macrobrachium rosenbergii) and the monsoon river prawn (M. malcolmsonii) provided scope for the farmers to diversify their culture practices.

Among the cultivable freshwater prawns, M. rosenbergii, the giant river prawn completely dominated the commercial freshwater prawn culture due to its superior cultivable attributes such as very fast growth, high market demand, hardiness, euryhaline nature and its compatibility to grow with cultivable fin-fishes such as Indian major carps, tilapia and catfishes - a viable option for enhancing farm income.

Monoculture of M. rosenbergii has produced production levels of 1.0–1.5 tonnes/ha in a 7–8 month production cycle.

Polyculture of M. malcolmsonii alongside Indian major carps and Chinese carps where production levels of 300 -400 kg in ponds and 50-83 kg prawn/ha/ eight months in reservoirs can be achieved. During recent years, the freshwater prawn-farming sector has witnessed quite impressive growth; with the State of Andhra Pradesh dominating the sector followed by West Bengal.

secluded areas to make a quick buck. This species was clandestinely introduced into the state of West Bengal possibly during 1994 from neighboring Bangladesh and quickly spread throughout the country, including into cold regions as well as coastal areas.

It is largely cultured in the states of West Bengal, Punjab, Tamil Nadu, Karnataka, Assam, Maharashtra, Andhra Pradesh and Telangana. Pacu, Piaractus brachypomus is also cultured in some states of India under monoculture or with Pangasius catfish.

The Government of India has also permitted the Nile tilapia, Oreochromis niloticus in aquaculture in late 2012, prescribing certain guidelines as a part of diversification of species for increasing overall fish production levels of the country.

In addition, this fish represents a lower level in the food chain, so its culture would be economical and eco-friendly. As per guidelines, farming of only mono-sex male/sterile (through either hormonal manipulation or cross breeding) is permitted and species recommended is Nile tilapia or improved strains/hybrids of tilapia.

Oreochromis niloticus is being farmed under monoculture in ponds. Recently it is also farming in cages of Indian reservoirs to enhance the fish production and to provide livelihood to local fisher folk in various states in the country.

Brackish water aquaculture in India is concentrated around the giant tiger shrimp, Penaeus monodon as the single most important species. India witnessed a phenomenal increase in the area under shrimp farming which occurred between 1990–1994, and the growth rate was phenomenal till 1995. In fact, farmed recorded shrimp production enjoyed in excess of a five-fold increase from 28 000 tonnes in 1988-89 to 144 346 tonnes in 2006-2007 and operating at around 100 000 tonnes over the years.

Among the coastal states, Andhra Pradesh is the largest producer of shrimp production in the country. Later its production

comes down significantly due to frequent occurrence of viral outbreaks particularly white spot syndrome.

In India, a major shift in shrimp related policy took place with the introduction of an exotic species of shrimp, viz, Penaeus vannamei. The pilot-scale introduction of P.vannamei initiated in 2003 and after a risk analysis study large-scale introduction has been permitted in 2009.

The introduction of vannamei in India occurred under controlled conditions with a clear procedure laid down by the government.

Initially, two companies, Sarat Seafood and BMR Hatcheries,

were given permission to import broodstock from approved countries and conduct trials in a restricted environment.

The introduction of vannamei in India

The Central Institute of Brackishwater Aquaculture (CIBA) and National Bureau for Fish Genetic Resources (NBFGR) conducted the risk analysis for the introduction of vannamei in India.

Following the risk analysis studies, the government decided for a large-scale introduction of commercial use of vannamei in 2009.

P. vannamei importation and cultivation guidelines were prepared

by the Department of Animal Husbandry, Dairying and Fisheries.

Coastal Aquaculture Authority (CAA), of the Government of India, Chennai is the agency for granting permission to import vannamei brood stock and for giving permissions for vannamei culture by farmers.

Recently, the culture of exotic, white leg shrimp, Litopenaeus vannamei, however, has attracted the farmers’ attention because of its fast growth, low incidence of native diseases, availability of Specific Pathogen Free (SPF) domesticated strains and culture feasibility in wide salinity range.

With the production levels of 10–12 tonnes/ha/crop of 3-4 months duration, the production of this species has reached to a level of 353413 tonnes during 2014–15 and P. monodon production declined significantly (Table 3 & Fig. 1).

To facilitate farmers in getting quality SPF vannamei seed, the Government of India set up a quarantine centre at Chennai and all vannamei brood stock is allowed to enter India after the consignment is cleared at this quarantine center at Chennai.

Currently, CAA has given permissions to farmers for farming vannamei in 22 715 hectares and allowed 135 hatcheries for importing vannamei broodstock for production and supply of quality SPF vannamei seed to farmers. In addition, certain marine/brackish water crab as high export prices have made fattening of species like (Scylla serrata and S. tranquebarica a remunerative farming practice.

Mariculture

Over the last decade, considerable changes have taken place in the diversification and production of mariculture in India.

Most significant is the emergence of oyster and mussel farming as a commercial aquaculture programme. Intensive research on various aspects of the culture of the Indian backwater oyster, Crassostrea madrasensis has been made and the technology has also been developed for the hatchery production of seed.

Mariculture in India, although limited to the farming of mussels and edible oysters undertaken in some coastal region of Kerala over the years, has successfully produced sea cage farming in recent years, initially with seabass and most recently cobia, which has shown the prospects of commercial mariculture in the country. Apart from increased production, India has several new technological developments like tissue culture of marine pearls, hatchery techniques for lobsters and ornamental fishes that have potential to make impact on the country’s economic development.

Amblypharyngodon mola etc.

Among the catfishes Sperata sp., Ompok sp., and Wallago attu. Efforts are being made to standardize the technology of mass-scale seed production of these species and their inclusion as a component of conventional carp polyculture, based on their regional importance.

In addition, there is a contribution from cold water fisheries, although insufficient for fish basket, it is of high value and lowvolume category with a projected volume of 1 percent. Important food cold-water fishes for food are mahaseer and schizothoracids belonging to the indigenous species and trout’s among the exotic varieties. Promotion of trout and mahseer farming in the upland coldwater region has also shown significant potential for aquafarming.

Availability of balanced supplementary feed for different life stages for diversified cultivable species and appropriate disease management measures are some of the important other developments.

Almost five-fold growth in mean national pond productivity in last four decades, i.e. from about 600 kg in 1970s to 2900 kg/ ha today is proof of the sector’s vibrancy. As the second largest aquaculture producer in the world, aquaculture in India is also considered as a thriving sector for meeting the increasing fish demand in the coming years.

The developmental support provided by the Indian Government through a network of FFDAs, BFDAs, and the Research & Development programmes of the Indian Council of Agricultural Research (ICAR) have been the principal vehicles for this revolutionary development.

In addition, additional support was also provided by various state governments, host of organisations and agencies like the Marine Products Export Development Authority (MPEDA), National Fisheries Development Board (NFDB), Rajiv Gandhi Centre for Aquaculture (RGCA), financial institutions, etc.

1 The golden spear

parus aurata translates roughly as ‘gilded spear.’ The fish is widespread across the Mediterranean, present north to the British Channel and south to Senegal, and rare north of the Bosphorus. It is a relatively hardy fish, able to cope with a wide variety of temperatures and salinities. This makes it a natural choice for aquaculture, and it is indeed farmed extensively: practically every country bordering the Mediterranean is a major producer.

Until fairly recently, farming of this species basically consisted of trapping wild individuals, then fattening them up for harvest. Captive breeding was only achieved in Italy in 1981-82; large-scale production was to take a further seven years. It was worth the wait: the fish proved highly adaptable to intensive rearing.

By the turn of the millennium, production had reached 87,000 tonnes a year.

Indeed, in some places at least, the Seabream industry appears to have been something of a victim of its own success: the conventional market for these fish is reaching saturation.

The answer for traders would appear to be twofold: to expand into new markets and to also transform their approach to existing ones. Value-added products will likely play a major part in this.

AQUA FEEDS IN THE SEA BREAM FARMING INDUSTRY

by Diogo Thomaz, Stella Adamidou, Dr Florian Nagel & Dr Hanno Slawski – Aller Aqua Group A brief history of sea bream nutrition

ea bream and Sea bass farming started in the early eighties in the Mediterranean, at a time where knowledge about the nutritional requirements of these species was practically inexistent. At that time only cold-pelleted feeds were manufactured with a small number of ingredients such as wheat, fishmeal, fish oil, soya and a variety of plant oils and meat meals.

Protein origin was mainly from fish and animals, and inclusion levels in the diets were very high, exceeding 50 percent. Fat content was very low, below 12 percent, and the main issue was to form a pellet, which could be consumed by the fish. As years passed, technologies evolved and from cold pelleted feeds we went one step further to steam-pelleted diets; in the mid 90s extruded feeds started to be produced extensively, turning the page in the history of fish feeds.

physical characteristics of feeds and improved digestibility of ingredients. Meanwhile academic and company researchers were working on the nutritional requirements of the species and the industry was continuously trying new formulas.

Extruders were the tools for the evolution of feeds. From gross protein, amino acids and fat levels, we moved to digestible protein/digestible energy requirements and from fixed diets to flexible diets. Fishmeal and fish oil substitution

The introduction of extruders

Extruders increased flexibility on the number, the type and the quantities of raw materials formulators could use. At the same time the new technology offered a number of options on the 38 | July | August 2016 - International Aquafeed

took place at the top of the feed companies’ agenda, research and EU funding projects and price and availability started to fluctuate considerably, adding some risk to feed production and cost.

In the year 2000 (until 2013), EU decided to ban land-based animal meals and turn the industry, that was struggling to find the best substitution for fish meal, exclusively to plant protein and fat sources. The need to reduce fishmeal and fish oil, combined with the EU ban, caused a number of changes in feed formulation.

Very soon it was discovered that Sea bass’ and Sea bream’s tolerance to plant materials were impressively high, but still lower than the tolerance of cold and fresh water species such as trout. As feeds were changing, the bass and bream industry in the Mediterranean kept growing rapidly, from a few tons in the early 80s to over 300,000 tons, increasing in biomass load and fish density but also health issues. Higher levels of premixes and a large number of additives are being used to cover different types of issues, such as liver and gut health, immune system enhancement, and pathology issues, all of which are types of stress, but also feed palatability and digestibility. Today we are at a stage where fishmealfree diets are discussed and tested commercially for some carnivorous species and this seems to be the inevitable future of fish feeds.

In the best case scenario, fishmeal and fish oil supply will be stable over the next few years, demand will always be higher than supply, and prices will have be on the rise, whilst aquaculture production will increase together with the demand for more fish feeds.

highly nutritive raw materials. This search for high quality raw materials has not gone unnoticed.

The fast growth and commercial attractiveness of the aquaculture sector has sparked high interest by raw material suppliers. The demand of the aquaculture sector for high quality raw materials has been answered by advanced processing methods for raw materials.

Vegetable protein sources can now be obtained almost free of anti-nutritional factors. And animal by-products can now be processed as gentle as LT-fish meal, resulting in improved palatability and nutrient digestibility. As a consequence, Sea bream feeds will contain less fishmeal and more alternative protein sources, whilst maintaining the required feed performance.

Whilst the scarcity of fish meal will intensify and fish meal inclusion levels in fish feeds will have to shrink further, the outlook is positive. The demands of the aquaculture sector have not only resulted in improvements of existing raw materials – also new raw materials are now commercialized for application in fish feeds. For example bacterial proteins, algae extracts and insect meals possess high potential for fish feeds and will become common ingredients in near future.

Compared to fishmeal, replacing fish oil is more challenging.

The high content of Ω-3 fatty acids in fish oil is seldom found in other oils of significant availability. But the also here, the market needs to have been addressed by inventive suppliers who have developed extract of Ω-3 fatty acids for application in fish feeds.

Therefore, fish requirements for fatty acids like EPA and DHA can also be met in future fish feed formulations.

The scarcity of marine raw materials is often discussed in a negative way. This scarcity is a reality. And raw material suppliers as well as feed producers are taking necessary steps to overcome the fishmeal and fish oil shortage. Reducing dependency on marine raw materials inherits enormous potential for the whole aquaculture sector, in particular for fish with

relatively high protein and energy demands like Sea bream.

Future direction in the use of nutrition to improve performance and fight diseases and stress in Sea bream

One of the main issues facing global aquaculture is safeguarding the health of farmed fish stocks by avoiding or diminishing stress and disease spreading. Husbandry-caused stress parameters are manifold and range from physical treatments (handling, grading, vaccination, transport) to environmental parameters (temperature, O2, CO2, pH, stocking density, feeding regime, light regime, microorganisms etc).

Diminishing stressful situations for fish could be done by provident management. However, tools that are well established for other species, like vaccination of salmonids are still obstacles in bass and bream farming due to limited availability of vaccines, antimicrobial resistance, limited flexibility of legislation, immature technology to apply vaccines, as well as challenging management issues.

A promising and effective alternative (without technical obstacles) to further alleviate the negative effects of husbandry could be the utilization of functional feeds.

Under stress, the challenged immune system requires support to overcome the acute and chronic impact of stressors. To secure good fish performance, functional feeds target the immune system and the metabolism of the fish by incorporated active ingredients.

The function and the mixture of active components can support the whole of the immune system of the fish in an optimal way, both the innate and adaptive immunity. A stimulated immune system can improve both robustness and performance of fish.

For bass and bream in the Mediterranean, the high water temperatures, limited oxygen at times and pressure by bacteria or viral diseases, have caused rising mortalities and depressed performance. Therefore, the evaluation and implementation of active components into functional feeds is playing a key role in recent and future stock assessment – pre-conditioning bass

and bream to cope with various stressful situations.

Feeds and feeding management must go together if Sea bream aquaculture is to become sustainable

Sustainability has two main facets: the environment and the business. In fish farming, and especially for species with high requirements in terms of protein and energy such as the Sea bream, these two facets are constantly being put to the test.

The profile in the ingredients being used for Sea bream feeds is constantly changing, in part due to the law (historical restrictions on the use of animal by-products for example), in part through consumer pressure (organic feeds or marine ingredients sourced from sustainable fisheries, etc.) but also due to availability and economic pressures on resources such as fish oil or fishmeal. These changes impact on the performance of feeds and force companies to continuously adapt their ways to fit new formulas.

Over the last decade we have seen an increase in Sea bream feed prices of 40-50 percent. This increase was not paralleled by an increase in the prices of farmed Sea bream. The replacement of marine raw materials with vegetable sources has had an impact on the growth and disease resistance performance of this species, mostly in a negative direction, with lower growth and higher sensitivity to stress and disease.

Companies have coped by changing management, especially trying to reduce staff and infrastructure costs. These days they achieve production of 60-80 tons per employee per year, from values that were half that 15 years ago. Still more needs to be done, especially in improving feed conversion rates and survival.

PAVING THE WAY FOR A SUSTAINABLE FUTURE

As a salmon farmer on northern Vancouver Island, AgriMarine had experienced crop losses due to toxic algae blooms, predators and escapes. Preventing the interaction between the farmed salmon and its marine environment seemed like the right solution to these challenges, and lowering the high capital costs of land-based systems was key.

t wasn’t too long ago that salmon farmers viewed closed farming systems with indifference or even contempt. Critics of land-based systems assured us that these systems were cost prohibitive due to their high-energy requirements, high land values, and the difficulty of building structures large enough to rear economically viable crops of fish. Indeed, AgriMarine faced the same issues when it was commissioned to operate a land-based salmon-farming pilot on Vancouver Island, British Columbia, 15 years ago. As a salmon farmer on northern Vancouver Island, AgriMarine had experienced crop losses due to toxic algae blooms, predators and escapes. Preventing the interaction between the farmed salmon and its marine environment seemed like the right solution to these challenges, and lowering the high capital costs of land-based systems was key.

With this goal in mind, AgriMarine’s team of engineers and salmon farmers embarked on a journey to create a sustainable, “green” rearing system. It wasn’t clear at the time that it would take over 10 years of R&D effort to arrive at the current concept for the production of fish. The Company set out to design and test a walled, floating enclosure that would enable the separation of cultured fish from the external environment.

Over the years, many materials were tested without success until a fiberglass foam sandwich formed under vacuum met the initial engineering criteria. Materials chosen for the first two designs, reinforced concrete and aluminum, were deemed unacceptable. The aluminum system would not able to handle the projected stress and wave pressures, and the concrete system was not easily handled due to material density - both were abandoned before prototypes were built. After a decade of research and development, AgriMarine had created a unique and revolutionary rearing system that was several years ahead of its time.

The foam sandwich concept met expectations in low energy environments, such as that found in the Guanmenshan Reservoir installation, in northern China. Shear stress testing determined that higher energy environments, such as that found in the ocean, would require a different materials configuration, so the AgriMarine team redesigned the containment wall layup. The new design provides both strength and flexibility to withstand the robust, highly energetic ocean environment.

A feat of engineering genius? You bet. However, creating disruptive technology has its disadvantages.

The industry responded with lukewarm interest and there was no quick adoption of the new systems.

AgriMarine implemented its proprietary systems in its own farms where the technology has been highly successful at producing healthy fish at a commercial scale, with excellent growth rates. The Company proved its system for the rearing of salmon and trout in Canada and in China, where the tanks operate in dissimilar water temperature environments.

The Company has completed the installation of a total of twelve AgriMarine System™ tanks in its farms in China and in British Columbia and continues to innovate and improve its technology.

Years later, we are now witnessing a wave of interest in closed systems that aim to mitigate disease 42 | July | August 2016 - International Aquafeed

FISH FARMING TECHNOLOGY transfer, sea lice infestations and increase production. This trend is now taking hold in Norway with many companies revisiting the floating system concept. AgriMarine was able to establish a foothold in the world’s largest salmon farming nation with an installation off the Norwegian coast for a post-smolt pilot project.

Faster growth rates and reduced disease

Closed systems, whether on land or floating, offer many advantages to the farmer and are increasingly more cost effective than when AgriMarine first began its research years ago. Upfront costs are still higher than conventional net systems, but capital costs can be amortised over a period and are offset by faster growth rates, reduced disease, sea lice and antibiotic use, and improved feed conversion ratios.

Managing the rearing environment is a priority for AgriMarine’s technologies. The AgriMarine System™ allows access to water from depths at which motile sea lice are not typically populating. At the 2014 North Atlantic Seafood Forum in Bergen, Norway, salmon farmers pointed to sea lice as the single biggest issue facing the salmon farming industry. Sea lice management dictates supply growth and prices. Approximately NOK 5 billion (USD$575 million) was spent in 2015 by the Norwegian salmon-farming sector on combating sea lice. More recently, this year’s headlines feature the devastating algal blooms in Chilean waters that affected that country’s industry.

Now farmers are seeking rearing environments that are escape-proof and that will aid in reducing levels of disease and sea lice. The race for finding alternative methods in the fight against sea lice is on.

Floating vs Land-based Systems

The AgriMarine System™ is designed as a flow-through, floating tank with ancillary life support and waste systems that can be deployed in oceans, lakes or reservoirs. AgriMarine’s tank design successfully combines the environmental and husbandry benefits of land-based fish farming with the low operational costs of open net pen aquaculture. Better control of the rearing environment, protection against sea lice and predators, temperature modulation and risk mitigation from toxic algae and low dissolved oxygen events are some of the advantages of this technology.

In addition to developing its proprietary aquatic farm management technology, the Company installed recirculating aquaculture systems (RAS) in a number of projects and sees value in utilising RAS technologies for applications where water access is restricted or where limited water resources are available for land based farm consumption.

AgriMarine’s farm in Lois Lake, British Columbia, utilises RAS systems in its hatchery and both AgriMarine System™ tanks and net pens operate in the lake to rear Steelhead salmon.

Closed systems allow the user to manage and optimise the grow-out environment for fish.

While both land-based and floating systems offer temperature modulation, waste capture and effective feed application, they differ in terms of water treatment and power requirements. Water re-circulation systems require ammonia removal technologies, whereas floating systems constantly pump fresh water from its environment, with the flow adjusted to reflect the size of fish being reared and ensuring proper schooling behaviour. Temperature and available dissolved oxygen are the most important variables for fish growth and both systems control these. The AgriMarine System™ includes oxygenation and variable-depth pump intake, to help avoid deleterious water quality conditions. Pumping water from different depths not only serves to maintain the fish at a comfortable temperature but also avoids the levels of naturally occurring sea lice, so that the tank does not propagate sea lice.

The operating head of water systems in floating closed containment is less than 1/10th of a metre, whereas landbased recycled are often as high as 20 feet. Given the proportionality of lift to energy cost in water systems, this is an order of magnitude savings over conventional land based recycle systems. Collecting all the waste food and excrement is only possible in closed systems.

Improved protection of smolt

Protecting smolt from sea lice infestation is a growing trend in aquaculture. Extensive trials are being conducted in International Aquafeed - July | August 2016 | 43

major aquaculture centres for the production of large, seawater-adapted smolt utilising closed-systems.

Shorter time in open net pens based on using semi-closed containment for post smolt production allows for better stock management and environmental controls. Reducing sea lice and lowering mortality rates during the most vulnerable period of the salmon production cycle are key goals in current aquaculture practices.

Young salmon are often too weak to survive the challenges of disease and sea lice after being stocked in an ocean environment. Reducing the time in net pens is proving to increase survival rates and leading to more robust fish that are able to withstand the marine environment as juveniles.

With increasing interest in large smolt in the industry, the AgriMarine System™ is the standard bearer for this type of this technology. The systems are utilised to produce healthier, larger smolt, up to one kilogram, before transfer to sea cages. While capital costs are higher than a net system, production costs will be reduced due to improved feed conversion, lower mortalities, higher biomass densities, improved fish welfare and lower cost of sea lice treatments. As well, better growth rates translate to faster inventory turns, and thus a better utilisation of capital.

Floating Raceway Technology

The Company is now turning its attention to improvements and innovations. Two years ago, it formed AgriMarine Technologies Inc. (ATI), the Company’s technology and engineering services arm. In addition to continuously improving and innovating its own platform, ATI offers design-build services, with a focus on Clean Tech rearing systems. Its farm serves as a testing base for the new technologies and components that are under development. Technologies are all tested in “real-life” situations, so those in industry who would like to adopt them can be confident that they will perform as advertised.

AgriMarine believes that innovation is essential to progress. ATI has developed proprietary Floating Raceway Technology (FRT) and is now installing its first commercial-scale system. Although raceway systems have been around for many years, the new FRT design provides the same optimisation of water quality as circular containment systems and can be deployed in shallower water bodies such as sheltered inlets, lakes, rivers, man-made ponds and rehabilitated gravel pits. In fact, ATI’s pilot project in Ontario converted a decommissioned gravel pit into a viable trout farm. FRTs are scalable, affordable and can be deployed in a short period of time.

ATI is at the forefront of the development of new technologies that seek to achieve economic and environmental benefits. We welcome industry participants to visit our farm to learn more about our innovations and to share their ideas and challenges with us.

VIBRATORY SCREENING OF OYSTERS Seed oyster production at The New Jersey Aquaculture Innovation Centre at Rutgers University (AIC) is a large-scale operation by any measure. The 2046 sq m facility next to the Cape May Canal in Cape May, NJ, produces diseaseresistant, fastgrowing seed oysters for commercial grow-out, research, and restoration of native oyster beds.

by Kason KekGardner, NJ Aquaculture Innovation Centre, Rutgers University

nnual production is more than 10 million seed oysters to meet customer specifications, in particular those of East Coast commercial oyster producers.

Sorting by size for counting and redistribution in the “nursery” is a frequent and essential operation in the seed oyster production cycle. Originally, sorting with a 0.6 X 0.6 m hand-held screener was a daunting task, according to Matt Neuman, lead researcher and technician for hatchery production at the AIC. “It took all day for a three- or four-man crew to complete each round of sorting,” he explains. “And the added weight of seawater mixed with the product took a huge toll on everyone’s shoulders.”

The search for a ‘better way’ led to replacing manual screening with a dramatically more productive, mechanical 762 mm diameter Vibroscreen™ circular vibratory screener manufactured by Kason Corporation. With one operator now completing each day’s sorting in less than two hours, the equipment paid for itself in the first season.

Aquaculture innovation at Rutgers

As the leading research and education hub for New Jersey’s aquaculture community, the AIC studies and teaches methods of commercially raising seafood, benefiting a wide range of stakeholders – from aquaculture entrepreneurs and restoration specialists, to governmental resource managers and nongovernmental organisations, to the fishing industry.

Among AIC’s projects is mass culturing of micro-algae using algal photo-bioreactors to increase yields of biochemical compounds with high potential value for food and pharmaceutical applications, as well as for shellfish (i.e., oysters) cultured for human consumption.

Seed oyster production: mimicking and accelerating nature

The Eastern Oyster (Crassostrea virginica) is among the shellfish species successfully cultured at the AIC using a micro-algae diet. The facility has been producing seed oysters from this strain since 2008. Seed oysters are small oysters, about 2–25 mm long, provided primarily to oyster growers for the half-shell market. They are also used to restore natural oyster populations or natural ecosystems, and for research.

While natural oyster populations in the Delaware Bay spawn in late June or early July, at the AIC broodstock (adult oysters which produce baby oysters) are moved into temperature-controlled tanks in January, given plenty of microalgae food, and are ready to reproduce by late February.

Fertilised eggs become microscopic oyster larvae, which are raised in filtered, sterilised seawater in 5 678 litre culture tanks. After two to three weeks, the larvae metamorphose into juvenile oysters called “spat.”

The growth cycle from spat to seed oysters takes several weeks to several months, depending on their intended size. Where oysters naturally clump together, AIC’s methodology yields individual oyster “singles” suitable for the half-shell market.

The first sorting operation in this growth cycle occurs when juvenile oysters are still under one millimetre in size, after spending about two weeks in filtered seawater in large “downweller” tanks, with regular feedings of cultured algae. Manual sorting in the downweller tank with a 0.3 X 0.6 m hand-held screen works efficiently for distributing the oysters at this tiny size to a series of 457 mm diameter “upweller” silos fed by raw seawater and whatever food it naturally contains.

As they grow, juvenile oysters are regularly sorted by size, counted, and redistributed in the upwellers to optimise growth and survival. The number of seed oysters placed in individual silos is based on volume determined by sub-samples. At full production late in the growth cycle, the AIC has 130 upwellers in use.

The AIC supplies some growers with seed oysters as small as two millimetres for cultivation in their

own upweller systems. The remaining oysters at AIC grow at about a millimetre per week. Sorting to prevent overcrowding and to separate oysters by size becomes more frequent as they grow, and with the increasing weight of the oysters, more challenging to sort with hand-held screens.

Looking for a better way

“More frequent” means dozens of sorting operations, as seed oysters grow to eight mm size and larger, with daily sortings during the last weeks of the growing cycle. Faced with staff diversions for sorting manually, as well as aching shoulders, the AIC’s Neuman took the lead in researching options. “We looked at every supplier, and learned that pretty much every clammer in New Jersey uses Kason screening equipment,” he says.

He credits independent representative Chris Dugan for streamlining his evaluation and purchase. While visiting Kason’s headquarters and laboratory in Millburn, NJ, Mr. Neuman and an AIC staff engineer observed the circular vibratory screener during test runs using a batch of seed oysters in different sizes. Mr. Neuman decided on a 762 mm diameter model for optimising sorting yields and processing time.

Problem solved with circular vibratory screener

The K30-1-SS Vibroscreen™ circular vibratory screener now in use at the AIC is a single-deck model with four interchangeable screens sized at 8mm, 6mm, 4mm, and 2mm mesh. Typical sorting operations involve several screen changes. Mr. Neuman also looked at Kason’s multi-deck models for sorting multiple sizes simultaneously but determined “they were more than we needed for the scale of our operation.”

The screener’s corrosion-resistant stainless steel construction is essential for the AIC’s salt water environment.

Because salt water is also corrosive to tools, Neuman specified a clamshell lid, quick change option to allow easy screen changeover without tools.

The deck of the circular vibratory screener is suspended on springs that allow screens to vibrate freely. An imbalanced-weight gyratory motor creates multi-plane inertial vibration that controls the flow path of material on the screen surface and maximises the rate at which undersize seed oysters pass through the screen while oversize ones migrate in controlled pathways to the periphery and through the discharge spout into a small tub. Undersize oysters exit from the lower discharge into a separate container.

Flow patterns can be adjusted by repositioning a bottom eccentric weigh relative to the top eccentric weight. The AIC unit was delivered with factory settings of 45 degrees, which Mr. Neuman fine-tuned to 60 degrees, maximising efficiency for his application. “Adjusting the angle on a bottom weight involves adjustment of only one bolt,” he says.

Oysters are hand-fed slowly from a large funnel into the centre of the screener at a rate of about a litre over 30 seconds. Mr. Neuman’s team is developing a new feed method using a corkscrew design to speed up this process while controlling the flow rate for a steady feed.

The AIC set up its vibratory screener on a mobile cart and plugs it in where needed. The screener allowed Mr. Neuman and his team to discard their old upweller hand-held screens, making life easier on the seed oyster production line. He says, “The new screener has freed seasonal staffing for other tasks, and it allows us to get bigger seed oysters out earlier, which our growers like.” aic.rutgers.edu International Aquafeed - July | August 2016 | 47

FISH FARMING TECHNOLOGY #3 UV TECHNOLOGY IN AQUACULTURE When designed, installed and maintained properly, UV systems are extremely robust, reliable and effective.

Pentair Aquatic Eco-Systems (PAES) is a leading manufacturer of UV water treatment systems for use in a range of industries.

by Michael Annett, Sales/ Business Manager UV Systems, Pentair Aquatic EcoSystems

PAES has particular expertise in designing and supporting UV systems in aquaculture field applications.

In addition to new installations, PAES also provides consulting and support for UV systems that are installed in existing aquaculture facilities. UV treatment has been used successfully for approximately six decades to treat and sanitise water in many critical applications.

In this article, we will describe the array of UV system configurations along with their associated lamp technologies, to serve as a high-level guide to important design and operating considerations for UV systems.

UV process discussion

Ultraviolet or UV energy is located in the electromagnetic spectrum with a wavelength shorter than that of visible light and longer than x-rays.

When UV systems are deployed to treat water, the reactions are instantaneous, taking only a few seconds to occur, without the creation of disinfection by-products.

Chemicals are not required and the associated hazards of chemical handling and storage are not present. UV treatment does not alter colour, odour, taste or pH. As such, UV processes are environmentally safe and are considered ecologically-responsible technology. The science behind UV technology is well-established; and its efficacy is well-proven.

UV systems are trusted in a wide range of industries including drinking water production, aquaculture farming and other applications.

UV light is comprised of electromagnetic radiation of wavelengths ranging from 100nm to 400nm: UV-A (long wave UV): 315-400nm UV-B (middle wave UV): 280-315nm UV-C (short wave UV): 200-280nm Vacuum UV: 100-200nm

Disinfection

When a UV system is used to treat water, UV light at the 254nm wavelength penetrates the cell wall of microorganisms that are present in the treatment water.

The amount of UV delivered to the organism is called the dose. The UV energy permanently alters the DNA structure of the microorganism in a process called thymine dimerisation. The microorganism is not destroyed, rather it is ‘inactivated’ and rendered unable to reproduce or infect.

Photo catalysis

Another useful way that UV can be utilised is in the

Enclosed UV reactors

destruction of oxidants that are present in post-treatment water in the form of residuals.

Ozone (and some other oxidant chemicals) can be eliminated by the application of UVC radiation.

UV energy in the wavelength of 254nm has the ability to catalyse ozone into harmless oxygen and water. UV is very effective at destroying ozone (O3).

O3 molecules absorb 254nm UV radiation and this absorption causes decomposition of the O3 molecule.

O3 concentrations at less than 0.5mg/l can be eliminated with a UV dose of 60mJ/cm2. 1.0mg/l ozone concentrations require a minimum UV dose of 90mJ/ cm² for complete destruction.

UV reactor types

UV reactors for processing fluids are generally either enclosed or oriented in channels without an enclosure.

UV reactors can be in-line in a pressurised piping system or fed by gravity without requiring pumps.

Enclosed reactors

Enclosed reactors can be installed vertically or horizontally, in an “L” shape or “U” shape, or with the inlet and outlet on opposing sides. They are cylindrical and can be manufactured from stainless steel, various plastics and polymers such as PVC, HDPE and others.

Open channel and gravity-fed reactors

Open channel reactors are either installed in concrete channels or in pre-manufactured troughs, typically stainless steel or fiberglass reinforced plastic (FRP).

The lamps can be oriented horizontally in racks or mounted vertically, perpendicular to the flow. Open channel systems can treat very large flows and are economical if gravity feed is available. Gravity fed reactors can also be offered in enclosed FRP vessels with the lamps mounted vertically.

UV lamp technology

UV lamps used in disinfection and photolysis applications are categorised into two basic types: low

pressure and medium pressure. Both types of UV lamps utilise mercury which becomes vaporised when energised by the application of electricity.

As a result, photons are generated in the UVC spectrum. The following are characteristics of both lamp types: 1) Low-pressure/Amalgam: Monochromatic emission; 254nm UV efficiency 30-35%, as portion of Input Power Medium Power UV-C Output (Input Power up to 320W to 500W) Long lifetime (8000-18000 hours) <5mg mercury content on Mercury vapor pressure = 0.007 Torr Operating temperature 40-140 C 2) Medium-pressure: Polychromatic Emission 220-280nm UV efficiency 11%- 13%, as portion of Input Power High Power UV-C Output (Input Power 3kw to 30kw or more) Medium lifetime (6000-8000 hours) Up to 400mg mercury Mercury vapor pressure 100 – 10,000 Torr Operating temperature 600-900 C (Have Marketing insert a Sita MP photo)

• • • • • • •

The dose required to inactivate the desired target pathogen System flow rate Fluid temperature & salinity Space requirement of the installation location Power consumption Heat load imparted on the process Seasonal fluctuations in water quality All of these conditions should be considered prior to choosing a UV design. The most critical aspect of properly sizing a UV system is the UV transmittance (UVT) of the fluid being treated. Accurate knowledge of UVT is essential

Low pressure lamp systems are more energy-efficient than medium pressure systems, but are much larger due to the lamp size and quantity required to apply the same dose.

Medium pressure systems, however, generate much more heat, are more expensive to operate and have lower effective lamp life. Medium pressure UV systems have the advantage of smaller overall size and ease of maintenance due to the reduced numbers of lamps.

Both systems are commercially-viable and application appropriate and effective in terms of disinfection and photolysis performance.

UV Design Considerations:

There are several critical parameters which apply when designing or sizing a UV system.

In particular: • UV transmittance (or UVC light absorption properties) of the fluid being treated International Aquafeed - July | August 2016 | 49

FISH FARMING TECHNOLOGY for ensuring that a system will perform properly after it has been installed. Unfortunately, UVT is often overlooked or incorrectly estimated; which may result in poor UV system performance. Always consult a qualified expert or use a good-quality UVT meter to assure that UVT is properly taken into consideration.

UV Transmittance

The amount of UVC light that is absorbed by the fluid being processed dramatically affects the amount of energy available to apply the germicidal dose required to inactive the target pathogen or catalyse the target compound such as ozone.

A UVT analyser is used to measure the 254nm UVC light absorbed across a 1CM cuvette, providing a UVT measurement. UVT analysers are easily obtained and are inexpensive, valuable tools.

Table 1 illustrates the importance of providing an accurate UVT reading by showing the additional energy required at various UVT values.

Ninety percent UVT is a common UVT assumption for many UV applications.

At 90 percent UVT, 36 percent of the UVC generating capacity is absorbed by the water being treated.

If the UVT drops to 80 percent there is a corresponding loss of almost 57 percent of the UVC dose being absorbed. It is therefore essential to test the UVT at various times of year to ensure that the required dose is available at all times.

Water quality issues

Water quality affects the actual UV dose in several important ways.

First, turbidity and suspended matter physically shields the pathogen from the UVC dose, rendering the UV process ineffective. As a general rule of thumb, pretreatment to UV systems is generally recommended and defined as filtration down to 40 microns and 3 NTU turbidity.

Factors which have an impact upon UVT are: • Shielding – (Turbidity) • Organics • Chelating Agents • Halogen Stabilisers • Pharmaceuticals • Water Additives/Conditioners • Minerals especially Iron and Manganese • Sleeve fouling In UV systems, the lamps are enclosed in quartz sleeves to allow UVC light transmittance, while protecting the lamps from treatment water.

Minerals, hardness and organic matter can form on the outside

of the sleeves, reducing the amount of UVC light transmitted to the fluid, thus reducing the dose.

The UV system can be rendered ineffective if enough build-up occurs. Wiping systems can be employed to keep the sleeves clean. Periodic manual cleaning of the sleeves can also be done if wipers are not used.

If a drop in UV intensity is noticed, cleaning is likely required.

End of useful lamp life (EOLL)

Low pressure and medium pressure lamps have a useful lamp life. Lamp performance degrades over time as the mercury degrades within the lamp.

The lamp degradation process is unavoidable and eventually requires the lamps to be replaced. Lamps have life ratings which vary by type and manufacturer.

50 | July | August 2016 - International Aquafeed

FISH FARMING TECHNOLOGY Depending on the lamp type and manufacturer, the degradation loss over the lamp’s service life varies between 15 percent and 40 percent.

To ensure the design dose is applied over the complete life of the lamp, it is best to initially size the lamps for the 15 to 40 percent degradation loss. In this way, the lamps will actually produce a higher dose when they are new and will degrade to the design level until the end of lamp life, ensuring correct dose for the entire lamp life period.

Pathogen dose response

Pathogens respond to UV differently and they are inactivated at a variety of dose levels. When designing for multiple pathogens, it is critical to design for the pathogen with the highest resistance to UVC. The amount of pathogen being inactivated is referred to as log reduction.

Log-1 = 90%, Log-2 = 99%, Log-3 = 99.9%, Log-4 = 99.99%, Log-5 = 99.999% reduction Table 2 shows the dose required for various pathogens.

If log reduction is not indicated, this is the generally accepted dose value for inactivation.

Dose Determination

UVC dose is calculated using an ‘Ideal Reactor’ referred to as a collimated beam.

A collimated beam is laboratory apparatus that is used to deliver very precise UV doses to samples of fluid containing the target organism or chemical that is to be inactivated or decomposed.

The UV beam is comprised of uniform UV light that is easily quantified.

A petri dish is used that contains a thin layer of fluid with the target organism or chemical distributed within.

This is intended to represent perfect hydraulic design. The dose required for log reduction is considered ‘Ideal’ and is the base comparison for reactor performance (efficiency) and used to determine inactivation rates of organisms or chemicals.

Conclusion

UV systems are effective, economical, environmentally responsible, and low maintenance tools for disinfection and photo catalysis for aquaculture facilities.

Attention to design and actual operating conditions are critical to reliable performance. Proper dose, UVT and EOLL conditions are frequently overlooked or designed with an unrealistic UVT causing poor performance. It is therefore essential to consult with a reputable, experienced UV provider prior to installing a new system or retrofitting an existing system to ensure satisfactory consistent UV performance.

UVT testing routinely is inexpensive and ensures that the system operates as intended; systems can be designed to pace the lamp output based on flow and UVT in order to obtain lower power consumption on both lamp types.

REMOTE CONTROLLED CLEANING RIG - FNC8 The Flying Net Cleaner 8 (FNC8) is an easy operated powerful, remote controlled net cleaner. It can be mobile controlled as well as controlled from the control room. The movements are unique, as it “swims” along the net in the cage, and cleaning with high-pressure seawater. The lack of physical contact between the net cleaner and the net ensures no damages or tears to the net, thus reducing risk of fish escaping.

The FNC8 is a patent applied principle, ensuring that the rig is in balance whether it cleans horizontally, vertically or upside down. This quality simplifies choice of suitable cleaning direction for any net type.

Cleaning speed is important for the operator, and FNC8 is able to clean at an incredibly fast and efficient rate – saving both time and reducing costs.

Flying Net Cleaner 8 standardly includes ROV components that are easy to clean and disinfect. It is a user-friendly device with built-in auto functions, sensors surveying the cleaning process, and advanced camera systems. The new Flying Net Cleaner 8 is prepared for collecting rinsed off organisms.

Twice as fast as the current systems The FNC8 has a cleaning capacity, which is twice as fast as the current systems with minimal spread of dispose (ready for collecting) and surveillance sensors for improved pressure during the cleaning process. The FNC8 also features thrusters, which are used not only for propulsion but for placing the cleaner close to the net without sharp wheels or belts. The FNC8 also boasts Rugged component and solid and open construction; making it easy to maintain and disinfect.

FISA REBRAND

Fish net makers Fisa rebrand following us$4.5 million investment Fibras Industriales S.A. (FISA), a global leader in aquaculture net manufacturing & fabrication, has announced that they have launched their new webpage www.fisa.com.pe and logo.

As leaders in the production, distribution and sales of nets, twines, floats and ropes for the fishing and aquaculture sectors, they also have impressive shares in the agriculture , sports, mining and construction markets.

With several decades of experience in building aquaculture cages, netting structures for the fishing of diferent species, sports cages and panels, and more, FISA boast a wealth of satisfied customers that include MarineHarvest, Copeinca and TASA to name but a few. FISA’s team of engineers are experienced in both the design and asembly stages of net production; which they tailor to meet each scenario’s specific requirements.

As part of the company’s evolution, that has included the investment of over US$4.5 million in new machinery and net loft over the last 3 years, FISA has recently refreshed their traditional logo in favour of a newer one in order to provide a “new look and feel.”

According to FISA’s Commercial Director, Yoni Radzinski, decided after careful consideration that it was time to choose a new logo that provided a better reflection of who the company is today, describing the newer logo as being, “modern and driven to provide superior quality and services across the globe.”

Specialised engineers Fisa’s R & D department has specialised engineers that are constantly evaluating the efficiency of their products. Equipped with a modern laboratory in which their engineers continuously measure all processes, they ensure that their products reach the quality standards required by the vastly different industries in which their customers operate.

Among the company’s recent investments are new extrusion lines for PE & PP, a new depth stretching machine, upgraded their twisted knotless (Shogun) machinery, have purchased several new knotted weaving machines and increased capacity for the Raschel knotless netting production lines.

Over the years, the company has expanded its range of products,

making them able to complete the full range of needs for its customers, not only in fishing and aquaculture, but also in offshore aquaculture, agriculture, sports, safety and specialised netting.

All of FISA’s products are submitted to stringent quality control tests (the company has ISO 9001 certification for entire production process) to ensure such properties as durability, ductility, rupture resistance, resistance to abrasion and UV exposure are to the highest possible standard. www.fisa.com.pe

PESCA PEX PIPE - THE BEST CHOICE FOR FEEDING SALMON Pesca Pex Pipe, the most recent feeding pipe to hit the aquaculture market, is very competitive both in terms of durability, feed distribution and maintenance. In addition, Pesca Pex is certified antistatic=10 in 6-10 ohms. Pesca Pex pipe is available from 20 mm and is also suitable for hatchery use.

Pesca Pex offers many advantages for the salmon farmer. Featuring a very smooth inner surface, which means less friction and much more gentle treatment of feed pellets, Pesca Pex Pipe also gives off less dust and also reduces blower pressure to distribute the feed at long length. At the same time, the inner surface is very strong and there will be no gaps and cracks that can lead to clogging of the pipe, as the dust/pellets cannot sit on the smooth surface; so there will be no stops in feeding and no repairs of the pipe. The producer guarantees 3 years durability or distribution of 2000 tonnes of feed.

Pesca Pex is produced under very high pressure and high temperatures and the molecules are cross-linked during production. This means that the pipe is born with a memory and returns to its original form after extreme weather conditions or incidents including collisions with either a boat or truck.

Major economic benefits There are major economic benefits associated with the use of Pesca Pex. The pipe durability is proven to be at least 4-5 times longer than usual PE pipe.

After installation there is no handling or logistics related to the pipe- so focus is on feeding the fish- not repairing pipes.

Several Norwegian salmon companies have tried the Pesca Pex and they are all very satisfied with the performance of the pipe and are now regular customers.

Pesca Pex Pipe is distributed by Danish company AquaProcess, who is a well- known supplier of high performing products to the fish farming industry globally. www.aquaprocess.dk

The main exhibition of the aquaculture sector of the southern hemisphere overcomes the challenges of the climate and of the environment to offer the best fair experience.

Puerto Montt (Los Lagos region) will be the venue of the aquaculture world during AquaSur 2016, a city that poses constant challenges to the organisation to provide a first-level structure, in line with its status of the largest exhibition in the sector in the Southern Hemisphere. Four months into receiving public, the organization already has 85 percent of committed booths.

Puerto Montt is the aquaculture capital of our country and between October 19-22 it will become the world center of this business area when AquaSur 2016 begins.

Deploy the enormous fair that projects more than 20,000 visitors, with more than 10,000 square metres of exhibition, is a true giant that requires a careful and potent logistics to provide the best experience for both exhibitors as to the visitors.

“For example, since the climatic conditions of Puerto Montt are slightly adverse, it is necessary to use generators capable of running 24/7, to maintain a stable temperature inside the exhibition site during the whole fair”, explains Juan Pablo García, project chief of Editec Publishing Group, organizers of AquaSur 2016.

In order to have everything ready at the time of opening its doors, the advance team of AquaSur 2016 started the work of preparing the ground, no less than eight months before the event, beginning in March to prepare the location. “Most of this land should be compacted with heavy machinery and filled with gravel to provide a stable platform without variations in its topography, in this way both the visitors transit, the booths and the different exhibition platforms will be in an ideal way to receive this celebration of the aquaculture industry” says Garcia.

As in 2014, the sector where the fair will be located is in the outskirts of Puerto Montt, which was choose by its closeness and ease of access from different cities in the south of the country, and because it allows AquaSur continue its steady growth recorded since its first release in 2002.

“This growth comes with challenges that we must respond”, analyses Garcia. “For example we have increased the special parking area, which allows us to host more than 1,850 vehicles as safe and comfortable as possible,” the executive added.

One of the most interesting logistical challenges is about the water supply. “Far from being a major problem, we decided to implement a complete hydraulic system that will feed areas of restaurants and meals, as well as services. We are well aware that the eyes of the aquaculture world will be in AquaSur 2016, so we are putting all our resources and efforts to provide a high-level event”, concludes Juan Pablo García, project chief of the fair.

Food for thought!

Edinburgh to host Aquaculture Europe 2016

Aquaculture Europe 2016 will take place at the Edinburgh International Conference Centre (EICC) from September 20-23, it will the first time the event is to be held in the UK. AE2016 is organised by the European Aquaculture Society with the cooperation and support of Marine Scotland, part of the Scottish Government, and The Marine Alliance for Science and Technology for Scotland. The event is Gold Sponsored by Biomar.

The event theme ‘Food for thought’ means something to think about, something to be seriously considered and something that provides mental stimulation and nourishment.

Aquaculture in Europe has plateaued resulting in overall output remaining more or less constant in volume since 2000. AE2016 will present the latest science to support further development, and industry panels will discuss key opportunities. It will also identify areas to encourage further sustainable growth in aquaculture. The morning plenary sessions will address different aspects of the event theme in a novel way.

Aquaculture Europe 2016 Industry Forums Here is an overview and short description of the Industry Forums being organised during AE2016. Full programme details will be updated at the AE2016 web page.

Tuesday, September 20. 13:00-18:00 Mentheit Room Best Practice in Percid Fish Aquaculture This workshop will summarize the current state of BEST PRACTICE in percid fish aquaculture, pertaining to reproduction and on-growing as well as broodstock management, quality control, training and marketing. Speakers from industry and applied research will share present their view. Further topicrelated contributions are invited from all fields of technology, biology, market and supply chain research as well as case study reports and investment models.

Wednesday, September 21. 10:30 – 17:30 Mentheit Room The UK Aquaculture Initiative The UK Aquaculture Initiative is a joint BBSRC (Biotechnology and Biological Sciences Research Council) and NERC (Natural Environment Research Council) initiative to support high-quality, innovative research and research translation within a growing community of people working together towards a mutual goal of developing a healthy, safe and sustainable UK aquaculture system.

This cross-research council initiative will bring together diverse expertise, knowledge, skills and facilities to deliver innovative approaches to solving industry challenges. In doing so, it will strengthen the research community to underpin the long-term

needs of industry through interdisciplinary research, research translation, and the provision of training.

Wednesday, September 21. 14:30-17:30 Lowther Room Salmonview seminar: Growing larger fish in RAS systems There is an increasing trend to grow salmon to larger sizes in recirculation systems – although growing market-sized fish is still only done on a very limited basis, more and more companies are looking to release larger post-smolts to sea.

This seminar will look at the challenges and opportunities offered by the trend, with insights offered by a range of experts – academic researchers, industry technicians and commercial producers of RAS equipment – from Scotland, Norway and the Americas.

Thursday, September 22. 10:30-17:30 Lowther Room EAS/EATiP Day: DEVELOPMENT vs. STAGNATION: Defining issues and identifying needs Despite the stagnation in EU aquaculture development, both in shellfish and fish farming, during recent years, the multiannual plans required for access to the new European Marine and Maritime Fund (EMFF) set out how European Member States (MS) intend to overcome the bottlenecks that are inhibiting growth in their national aquaculture sectors, and provide forecasts of production growth over the funding period.

Thursday, September 22 10:30-17:30 Lammermuir 2 Room The use of cleanerfish in European aquaculture Sealice control is important for the salmon farming industry.

If allowed to develop without control in the salmon farms, sealice will be a problem to the salmon, and might impact wild salmonids. The use of and cultivation of cleanerfish started in the late 1980 ties, but already in 1976 a salmon farmer in Norway was using ballan wrasse for sealice control in the cages! Through the 1990-ties, the salmon industry relied heavily on medication to control sealice, but with increasing resistance developing in the lice towards some of the medicines many non-medical methods to prevent and control sealice are under development. Now the most important of these are biological control using cleanerfishes such as lumpfish and wrasse. These are partly caught in the wild and put into the cages, but to an increasing extent coming from specialized farms producing lumpfish or ballan wrasse specific to the purpose.

The AE 2016 Cleanerfish Industry Forum will focus on the actual use of cleanerfish in the salmon industry today, and will be an open discussion arena where farmers, scientists and other interested can discuss experiences, new knowledge and also identify knowledge gaps.

AQUACULTURE UK

Nestled at the foot the Cairngorm Mountains, amongst some of the most opulent countryside one could imagine, you will find the small picture postcard town of Aviemore. For the winter months at least, you could be forgiven for thinking that you were in an Alpine ski resort, as skiers from all over the world head north to tackle the challenging North-East Scottish slopes.

However, every other year when the snow thaws, the two day spectacular that is Aquaculture UK takes place. Now swelling to accommodate upwards of 130 thousand exhibitors, Aquaculture UK took place from 25th to 26th May 2016 at the Aviemore Highland Resort in Inverness, United Kingdom.

The very latest developments and innovations This event gave those present to view some of the very latest developments and innovations in the aquaculture industry.

A truly international event, with industry leading exhibitors from over 30 countries occupying a myriad of booths within the very capacious conjoined marquees, the tens of thousands of fish farmers, journalists, industry experts and potential buyers and sellers who attended were certainly warmly welcomed to the exhibition.

Now in its tenth year, Aquaculture UK ventured into new territory as year as 5M Publishing took the helm for the very first time. Although former showman extraordinaire David Mack was still on hand to ensure that the smooth transition of the shows ownership took place with as few glitches as possible.

Delivered with aplomb Everyone concerned delivered their tasks with absolute aplomb, with the show’s layout ensuring that all areas were accessible and there were no dead-ends or easily forgotten corners, although the marquee was very cold on the first morning. All areas were well lit but perhaps most importantly, there was an entire army of blue-jacketed 5M staff on hand to ensure that any issues were soon ironed out.

Greeting attendees at every stand were the great and good of those with a vested interest in the technological side of aquaculture. Each stand, as you will see from the array of pictures that accompanies this article, was manned by exceptionally well presented, knowledgeable and friendly ambassadors for their respective brands. If you had a question, they were more than happy to answer it – or exchange business cards, and in some cases, even swap a joke or two!

The conferences held in the main marquee’s annexes were also well attended and informative, with some

of some really tricky subjects challenged absolutely head on and without hesitation. In some cases in fact, some conferences were so well attended that there was standing room only.

The Gala Dinner occupied the evening in between the show’s two main days. The entertainment was light with a traditional band warming up proceedings before a flavoursome three-course meal was served.

After the awards were presented, the after dinner speaker raised a titter or two from the large multi-national audience, shortly before everyone retired to bed in preparation for a busy second day.

Thank you Aviemore, and goodbye

The final day of the conference offered attendees the opportunity to cement relationships formed on day one of the show, as well as reflect on what was for many a very worthwhile experience. And as the sun shone on those packing up following a very rewarding two days, and the 130 or so exhibitors dispersed across the globe, only one regret remained – that this show is biannual, so see you in two years and thank you Aquaculture UK 2016.

Vincent Vieugue, Fluid control My name is Vincent Vieugue I am living in Stavenga and I work for Fluid control. We have been working for more than twenty years in the oil and gas offshore industry and because of the current situation I’m looking to see what we can actually do for the aquaculture business.

We have some knowledge and expertise that could eventually help the aquaculture market, so that’s why I’m looking around to try and find both suppliers and customers.

I heard about this event as I have a partner that I am already working with in Bergen, they said that you should come as this is the place where you can meet the people really involved with materials and supply rather than just the biology types of topics.

I need to learn about what kind of equipment system, the volume that people are buying. So it’s been very interesting and I‘m learning a lot.

Morten Bjorn, Pentair Hello my name is Morten Bjorn I am an Aquacultural engineer, I have been working in the industry for about nine years, I started out in a small company now I’m with the Pentair Aquatic Ecosystems.

I am practically responsible for the EMEA region, which is Europe, middle East and Africa. Basically I develop solutions and work with the customer’s practical manager during installation and delivery of the equipment as well as in the design phase.

Pentair is pretty much a full equipment supplier for land based aquaculture, we are carrying a lot of different products that we produce ourselves so we have our own range of pumps. We also do fully engineered systems and that is where I am coming into the picture with my engineering background.

So we are able to provide complete system design and supply of a fully modern rasse farm. We’ve put in systems all over the world and will continue to do so in the years to come hopefully.

Hydrotech is part of Veolia Technologies, we do a variety of water treatment technologies, process water technologies and water treatment technologies. Hydrotech drum filters are on of those, but we also do a lot of clarification processes for wastewater treatment and a number of water purification technologies as well.

Our business is creating processed water systems and wastewater treatment systems for a variety of markets; with the aquaculture market being one of them.

Hydrotech is a regular exhibitor, Hydrotech drum filters are well used within the aquaculture industry, as are the systems that are produced by a company called Kruger Kaldnes, who are based in Norway and they are also a Veolia Water Technologies company as well.

We are a global company, we are a French owned multinational but we have representation and manufacturing across the world including North America, Far East, Continental Europe, Africa â&#x20AC;&#x201C; so we have a global reach, so Aquaculture UK is not the only show that we attend.

the interview Stefan Dullstein Stefan Dullstein is Head of Industrial Segment – Aquaculture at Linde Gases. Here, he is responsible for management of R&D studies, market analyses, introduction of new products and training and aquaculture team supervision. Stefan has been with Linde for more than 15 years working in various water treatment roles and, prior to that, worked in wastewater treatment and research for the Institute of Environmental Technology at the University of Bremen. He has an engineering degree from the University of Stuttgart and a PhD in dynamic simulation in waste water treatment from the University of Bremen.

International Aquafeed magazine caught up with Mr Dullstein at Aquaculture UK recently, held this year at the Macdonald Aviemore Highland Resort, situated at the foot of the Cairngorm Mountains in Scotland.

Linde have many years of experience in the gas supply industry and have been long established as an international brand name. But who are Linde Gases and what is unique to the company that they are able to offer to the Aquaculture industry?

Linde Gases is an international gas company with more than 60,000 employees active in more than 100 countries, providing solutions for the gas industry and any other kind of application where you need gases, including aquaculture. So in the field of aquaculture we are developing solutions for the fish farming industry since the mid 1980’s.

Linde undertakes the research and development of all our aquaculture technology at our Innovation Centre in Ålesund, Norway. With its highly equipped laboratories demonstration tanks, the Centre allows aquaculture technologists to observe how the latest oxygenation technologies impact farmed fish development.

Since its opening in 2012 Linde has introduced the capability to run warm water trials to understand and assess the performance of its technology in high temperature water environments inhabited by more tropical species. Additionally, they have recently installed an external floating dock where technology trials can be performed in the surrounding fjord.

Are Linde currently developing any new aquaculture specific technologies, and if so, what are they and why is their function so important to the aquaculture industry?

The most important factor for achieving healthy fish is to have healthy water; thus, controlling the concentration of oxygen dissolved in water is crucial in aquaculture. Maintaining the right level of oxygen in water improves utilisation of feed, reduces fish mortality and reduces the need for antibiotics.

The latest development that we are presenting here is the Solvox DropIn unit, which can be used for sea cages when you have low oxygen concentration. Naturally in sea cages, you would always have enough oxygen from the surrounding water, but there are certain scenarios where extra oxygen needs to be added to ensure the fish’s wellbeing.

Are Linde currently in a position to offer a unique solution to any of the major issues that currently face the aquaculture industry, such as sea lice?

Sea lice treatment is indeed one of the key applications of the Solvox DropIn unit. Sea lice are parasites well known to the aquaculture industry for posing a significant threat to fish farmers. They can compromise the health of fish, and damage their host’s skin through feeding, causing lesions

and infections through viruses and bacteria. Though they occur naturally in the marine environment, sea lice can represent a particular issue among farmed fish where a more concentrated population means that infestations can spread quickly.

In the summer season in particular, low oxygen concentration results in farmers being unable to continue feeding as they would like. The impact of sea lice and resulting treatment also affects the need for additional oxygenation. In Norway, farmers start pulling skirts around their cages to prevent sea lice eggs getting into the cages or to give full cage coverage during sea lice treatment, which means that providing oxygen to the water is all the more important.

Are you aware of any of your competitors’ products, and have you shared their experiences of using them, how do you feel that the solutions that your competitors offer compares to the solutions offered by Linde?

We are aware that there are solutions on the market with perforated hoses, but feedback from our customers is that they provide poor handling. Based on this, we developed a solution that can simply be dropped in to the water. Solvox Dropin can be lowered into the water with a crane from a boat and is operational within 15 minutes.

The booth here is not big enough for us to exhibit the entire Solvox package, which comprises the Solvox DropIn twin kit including two drop-in units together with automatic gas dosing, power connections for the pump and an optional oxygen probe fully integrated into the unit. The probe allows the user to easily gauge that there is the right concentration of oxygen within the cage.

When do you believe that this new product will be made available and which markets will it be launched in? Also, have Linde had the opportunity to test the product yet?

The product will be available worldwide. We have run trials in Norway and Tasmania to test it during summer season, allowing us to hold trials every six months. We are first going to launch in these geographies and anticipate a global rollout later in the year.

Other than Aquaculture UK, do you exhibit your products at any other shows?

We have also exhibited at Aquanor in Norway and look forward to showing the product at more global shows as the year goes on.

Tom is currently doing a foundation degree in agriculture and plans to top-up to a BSc degree next year. He then hopes to do the Harper Adams MSc Aquaculture course, led by Professor Simon Davies, professor of mono-gastric nutrition and aquaculture.

AquaBioTech Group will be supporting future opportunities for the aquaculture Masters programme at Harper Adams University. Two of Professor Davies’ previous Masters students already work there as full-time employees in Malta.
