Publisher – International Aquafeed and Fish Farming Technology
Viewing the content that International Aquafeed and Fish Farming Technology provides each month in a positive and enthusiastic way will assist in this technology transfer. Our contributors, columnists and staff are dedicated to explaining the reasons behind the technological subjects they are writing about.
But first let me comment on an event held in mid-March 2024…
The lead feature we carry this month is from the Monaco Blue Initiative (MBI) 2024 which, while aquaculture was not in itself fully represented, was referred to in several keynote presentations within the ‘private sector’ having an involvement in the ‘blue economy.’
It is not possible to side-line the aquaculture sector - and I refer to brackish water, coastal and ocean fish farming - when discussing a ‘blue economy’ that yields investment opportunities along with stewardship responsibilities for the environment.
The world’s population needs a secure protein food source with great potential and aquaculture has the scope over terrestrial animal production to meet the expected demand in an environmentally and sustainable way through greater marine fish farming.
We cannot rely on wild caught fish to satisfy demand forever. Fish are about the only wild animal that we feel relaxed at capturing and consuming, while all our other livestock proteins come from domesticated animals.
Ocean fish farming technology can be adopted by any country with a coastline and should not be seen as a blight on the seascape. Marine farming should be seen as a beacon of future sustainable food production which conserves the local environment in which it operates. Who better to ask to protect our oceans than those who work in it - and especially those that work ‘below water?’
For International Aquafeed and Fish Farming Technology magazines, this is an important month.
As we are published in the UK, May is the month in which we attend the bi-annual Aquaculture UK event in Aviemore, Scotland. This event is a major opportunity for Scotland and the rest of the UK to show off its best in fish farming and also attract to its expo facilities and conferences international companies, speakers and attendees.
We will be promoting participation on our 2024-25 International Aquafeed Directory and Buyers' Guide - with its new section on Fish Farming Technology. We welcome all companies providing equipment and services to consider listing their contact details in this year’s edition – free of charge. We publish the application form in Fish Farming Technology. Simply fill in and scan and return to Peter Walker at: peterw@perendale.co.uk.
Of course, you can add a logo and a text box to your entry for a small charge or even take a display advert - you can selecte a quarter, half or full page option - to attract greater attention and promote your products. Again, please contact my colleague Peter Walker to talk over any
additional inclusions, you would like.
We aim to make this coming year’s International Aquafeed Directory and Buyers Guide the most comprehensive and widely available directory in our aquaculture sector.
Once again, we are stretching boundaries. And once again we are adding extra pages to make this a bumper edition. There is plenty to read.
We kick off International Aquafeed with Nutrition Editor Professor Simon Davies’ editorial taking us through the use of medicated diets and why we use feed as a significant method for their administration (page 8). He points out the requirement for careful pre-planning in the use of antibiotics in controlling diseases, etc to avoid antimicrobial resistance, which is a serious threat. He discusses the development of vaccines and their advantages over using antimicrobials and refers to their development as ‘significant milestones’ in modern aquaculture husbandry.
Dr Brett Glencross on the other hand (page 13) talks about the blurring of the line between feed and food and makes the point that, in many cases, the utilisation of a potential food source that humans could consume might be better off reaching us via an efficiently produced fish or domesticated livestock source - such as salmon and chicken rather than pigs or cattle - and better meets our needs not only nutritionally but also for enjoyment.
We look at the development of ‘A turnkey solution for sustainable aquaculture’ (page 18) based on a discussion that took place at the 2024 North Atlantic Seafood Forum (NASF) that suggests a roadmap is now required to secure insect protein as a key source of supply for the aquaculture feed industry. Michel van Spankeren, Business Development manager at Protix in The Netherlands takes us through the suggestion.
Yechiam Shapira, Senior Researcher at Phibro Animal Health based in Israel discussed ‘How nutritional feed additives can support shrimp gut health’ (page 22) and while on the subject of shrimp Stephanie Frouel, Julie Castie and Maxime Hugonin of miXscience, France (page 24) delve into the topic of a new feed solution to mitigate EHP prevalence. There is so much more in this edition before moving on to the latest edition of Fish Farming Technology (FFT) magazine (page 39).
Our Norwegian Editor of FFT, Erik Hempel of the Nor-Fishing Foundation, leads off with his thoughts on ‘well boats’ which are designed today to protect both the fish they hold and the environment. After all, the transportation fish to processing facilities in ‘well boats’ is a critical aspect of farming that ensures the investment in feed remains maximised.
Heather Jones the CEO at the Sustainable Aquaculture Innovation Centre (SAIC) in Scotland writes for us on the impact local breakthroughs in innovation are having both at home and abroad (page 46). Technology is also helping to revolutionise shrimp farming as Melony Sellars, the CEO of Genics in Australia tells us in her article on page 50.
Our Managing Editor Jyothsna Nelloolichalil rounds out FFT with her reports on filtration and the power of up cycling in water management (page 52). And there’s much more as well.
This is the edition that goes to Aquaculture UK in Aviemore, Scotland (May 14-15, 2024 - see page 56) and two other international events as well. We give you a head start to these and other happenings.
I look forward to receiving your application forms to list your companies and services in our annual International Aquafeed Directory and Buyers’ Guide 2024-25. Happy reading and eventing!

In this section we normally tend to focus on areas concerning feed ingredients and feed additives in the main part. A fully balanced diet must obviously be a carrier for comprehensive nutrition and present within its matrix all the essential amino acids, protein, oils, and fats as well as the micronutrients like vitamins and minerals. However, there is a growing demand to provide in the feed, therapeutic agents such as antibiotics, vaccines and various antiparasitic compounds to treat fish and shrimp against a host of pathogens. These would be categorised as medicated diets.
Administering antibiotics and chemotherapeutic agents via fish feed in farm conditions is a common practice to combat bacterial and viral infections as well as parasites. Antibiotics are often incorporated into fish and shrimp feed to treat bacterial infections such as bacterial gill disease, furunculosis, and streptococcosis. These antibiotics can include oxytetracycline, florfenicol, and sulphonamides. They work by inhibiting the growth of pathogenic bacteria or killing them outright. The antibiotics are usually mixed into the feed pellets or coated during the manufacturing process to ensure uniform distribution. Antiviral agents like nucleoside analogues or protease inhibitors can be used to control viral infections such as viral nervous necrosis (VNN) in fish or viral infections in shrimp. These agents interfere with viral replication and can help reduce the spread of viral diseases. They are typically added to fish or shrimp feed formulations in precise amounts to ensure efficacy while minimising adverse effects. Parasitic infections like Ichthyophthirius multifiliis (Ich) or sea lice infestations in fish, and various parasites in shrimp, can be treated with antiparasitic medications. Compounds such as formalin, praziquantel, and emamectin benzoate are commonly used externally. For oral administration, antiparasitic medications are usually mixed into the feed pellets to ensure ingestion by the affected fish or shrimp. Apart from specific antibiotics and chemotherapeutic agents, various feed additives with therapeutic properties can be used to support the immune system and overall health of fish and shrimp. These additives may include probiotics, prebiotics, immunostimulants, and herbal extracts. They help enhance disease resistance and reduce the incidence of infections, thereby reducing the reliance on antibiotics.
To comply with regulatory requirements and ensure food safety, strict withdrawal periods must be observed to allow sufficient time for the antibiotics or medications to clear from the fish or shrimp tissues before harvesting. Proper disposal of uneaten feed and management of aquaculture effluents are essential to minimize the environmental impact of antibiotics and chemotherapeutic agents used in fish and shrimp farming. Regular monitoring of fish and shrimp health, as well as surveillance for antibiotic resistance and other potential adverse effects, is crucial to ensure responsible use of antibiotics and chemotherapeutic agents in aquaculture practice. However, it requires careful planning, monitoring, and adherence to best protocols to minimize the risk of antimicrobial resistance and environmental contamination while ensuring the health and welfare of the aquatic organisms.
In the rapidly evolving landscape of aquaculture, the development and utilization of vaccines tailored to combat specific fish diseases and pathogens stand as pivotal advancements. Fish vaccines serve as a proactive measure, offering a sustainable solution to mitigate the risks posed by diseases, enhancing fish health, resilience, and
welfare. The process of developing vaccines for fish diseases involves meticulous research and testing. Initially, scientists isolate and identify the pathogens responsible for prevalent diseases in aquaculture. Subsequently, they employ various techniques such as inactivated pathogens, attenuated live pathogens, subunit vaccines, DNA vaccines, and recombinant protein vaccines to formulate effective products. One notable approach is the use of recombinant DNA technology to produce vaccines. This method enables the creation of vaccines containing specific antigens that trigger a robust immune response in fish without causing harm. Additionally, advancements in nanotechnology facilitate the development of nanoparticle-based vaccines, ensuring targeted delivery and enhanced efficacy.
Whist the aqueous route is common and also direct injection for vaccines, feed is becoming a main consideration as it would technical be easier than using skilled and trained personnel for routine vaccine administration. The oral route would be ideal in almost guaranteeing the vaccine can reach the systemic level across the gut barrier and become effective in ‘priming’ the systemic immune system. Many companies have worked on vaccine technology and faced the challenge of including these at an optimal dosage in fish feeds.
The application of vaccines in aquafeed offers several advantages. Firstly, it reduces the reliance on antibiotics and chemical treatments, promoting sustainable aquaculture practices and minimizing environmental impact. Secondly, vaccines bolster the immune system of fish, enhancing their resistance to diseases and reducing mortality rates. Consequently, improved fish health translates to higher yields and profitability for aquaculture operations. By targeting particular diseases prevalent in certain regions or species, aquaculture practitioners can effectively address local challenges, leading to more resilient and sustainable aquaculture practices.
In conclusion, the development and integration of vaccines for specific fish diseases and pathogens into aquafeeds represent a significant milestone in modern aquaculture husbandry. With ongoing research and innovation, the future holds promising advancements in fish vaccine technology, further revolutionizing the landscape of aquaculture.

An Ediburgh-based start-up is aiming to support the growth of the global sector with the development of a new, modular farm system fuelled by food and drink byproducts, as a sustainable and decentralised alternative to producing a scarce fishmeal ingredient.
Aquanzo is working with CENSIS – Scotland’s innovation centre for sensing, imaging and Internet of Things (IoT) technologies – to farm artemia, a species of brine shrimp widely considered to be the best source of protein available for feeding fish and crustacea. The project has received funding from Innovate UK and Biotechnology and Biological Sciences Research Council (BBSRC), and is being supported by Boortmalt – one of the world’s largest malting companies.
Artemis are typically found in warm, salty water, occurring naturally in salt lakes in the USA, China and Eurasia. The specific conditions in which they grow means the supply of the shrimp is very restricted –particularly for countries far away from their natural breeding grounds, which need to import them. The situation has been exacerbated recently by the Covid-19 pandemic and the war in Ukraine, which have hit supply chains.
The growing scarcity of marine ingredients has meant that feed increasingly relies on plant-based alternatives to fishmeal as a protein source. The current global average for marine ingredients in fish feed is less than 10 percent according to experts – substantially down on 70 percent 30 years ago. However, research testing the composition of feed has found that not only do fish prefer feed containing marine ingredients, they also tend to be healthier compared with consuming plant-based protein.
Rémi Gratacap, co-founder and CEO of Aquanzo, said: “One of the biggest issues aquaculture faces is the sustainability of feed and the dependency of fisheries for fishmeal. It is well known there is a crisis in fishmeal ingredients and we need to decouple aquaculture from maxed-out fisheries and find new ways of providing sustainable sources of protein to help the sector feed a growing world population. Farming, rather than harvesting, important components of feed like Artemia is a better way of ensuring greater control and scale, and is similar to what
is already being done with insect farms, only with marine ingredients.”
The modular, recirculating aquaculture system (RAS) being developed by Aquanzo at Heriot-Watt University would allow Artemis to be grown wherever they are required using the co-product of agricultural processes – in the first instance, the production of malt for the whisky industry. The water used to process malt is rich in minerals and organic matter – that can be used to raise brine shrimp and is currently largely treated as waste.
Deployed on land near agricultural processing facilities so that there is no impact on the marine ecosystem, the Aquanzo RAS system is expected to reduce the amount of CO2 created in the production of fishmeal by 20 percent compared with harvesting fish. All of the water will be reused to further enhance its sustainability.
Rémi Gratacap added: “it has been proven that fish prefer marine protein in their feed – studies have shown they eat much more if feed contains marine rather than plant-based protein. The composition of their feed also influences how much they grow and their natural resistance to health challenges. The system we’re developing will give fish farmers long-term access to a sustainable source of marine protein, helping to continue aquaculture’s growth, enhance the health of their fish, make use of another industry’s waste, and support aquaculture’s net-zero goals.”
As part of the process and technical development, CENSIS engineer will collaborate with Aquanzo on the development of an IoT-enabled array of sensors and a ‘data lake’ – essentially a centralised repository for data – to help its production team collect, store and process data. The technology will help the company progress towards the development of a fully mobile recirculating system, which can be located wherever agricultural by-products are available and remotely monitor the welfare and growth of Artemia.
Corinne Critchlow-Watton, project manager at CENSIS, said: “The Aquanzo system could help solve one of the biggest challenges aquaculture faces – applying cuttingedge technology to a longstanding problem. The system will use an array of sensors to provide data on the environmental conditions within it and how the Artemia are growing, such as water temperature and pH levels. This project demonstrates how IoT and sensing technology can be used in a range of sectors to help solve what might have otherwise been considered a biological issue.”

Innovafeed, a global leader in the production of insect ingredients for high-quality animal feed, petfood and plant nutrition, inaugurated its North American Insect Innovation Centre (NAIIC) in Decatur, Illinois on April 18. This pilot plant is the first step of the rising French agtech’s industrial expansion to North America and aims to scale up production and commercialisation of insect protein in the USA.
Innovafeed breeds Hermetia illucens, also known as black soldier flies, in state-of-the-art indoor farms, while efficiently repurposing agricultural by-products for its strategic partner, ADM, in a pioneering zero-waste framework. This innovative process yields insect meal, oil and soil amendment, which Innovafeed markets under the brand Hilucia.
The inauguration of NAIIC will be a milestone in Innovafeed’s expansion in North America. The choice of Decatur, Illinois, is not coincidental: located in the heart of the corn belt adjacent to ADM’s North American headquarters and the world’s largest corn mill operations, with hundreds of processing plants across multiple States, the region offers high potential for multiple sites to be deployed in the future. The broader area is also a historical innovation hub for the agro-industry, making it a strategic location for Innovafeed to serve its core markets. Since 2023, the company in partnership with ADM, already has commercialised Hilucia insect ingredients for the petfood market in North America. As part of this effort, ADM has invested in a comprehensive R&D study at the University of Illinois at Urbana-Champaign, with results to be released later this year demonstrating the nutritional and health benefits of its ingredients. Future opportunities with other types of animal feed are also being explored as part of the comprehensive partnership between the two companies.
IFFO’s Members Meeting took place in Miami from April 16-17, gathering 220 delegates from 29 countries, representing the fishmeal and fish oil sector, the aquaculture and nutraceutical industry as well as scientists and certification programme representatives.
At a time when the first anchovy season is starting in the North-Centre of Peru, the speakers shared positive expectations for a rebound in fishmeal and fish oil production to take place in 2024 after last year being marked by the El Nino/La Nina phenomenon.
With 20 speakers, the emphasis was very much on market trends and science and how evidence-based considerations can help frame the understanding of the sector and its contribution to the global food system.
“Everything starts with facts and data. These have to be our North Star to support informed decision making in a wide range of fields such as fishery management, traceability, mitigation of environmental impacts, enforcement of labour rights” stated Petter Martin Johannessen, IFFO’s Director General at the end of the meeting.
IFFO’s net meeting will be its annual conference in Lisbon on October 21-23, 2024.
Irecently came across an interesting paper [https://doi. org/10.1136/bmjgh-2023-013511] which suggested that instead of eating beef, we should rather eat anchovies. The logic was simple. Anchovies are healthier for humans to eat than beef, being packed full of omega-3 and other important micronutrients. Anchovies are also more efficient to grow than beef (being cold blooded and produce a much smaller carbon footprint on kilo per kilo basis), and therefore would have less impact on planetary boundaries. But what the paper failed to capture is that food is not just simply about nutrition, it is also about enjoyment and culture.
The simple fact is that much of the world could survive on anchovies, but if given a choice they would rather eat beef, or chicken, or salmon. Choice, and the ability to produce food that adds not only nutrients, but also enjoyment to life is a key part of the food story. And this brings things to the crux of the issue, it
is easy to sometimes get lost in the divide between what is food and what is feed. Yes, anchovies are packed full of important nutrients, but just because we use them mostly to make fishmeal, doesn’t mean we can keep those nutrients in our food-chain. In fact, we do, through indirect consumption.
Feed ingredients in effect are indirect food. This the reason why regulatory bodies put stringent regulations on things like contaminants in feed ingredients because these nutrient sources are only one-step removed from our direct food. So, if a choice is made to not consume something directly, like anchovies or wheat, but instead feed those nutrient sources to a salmon or a chicken respectively, then this often represents the next best option of using resources not desired in our food directly. Indeed, the more efficient the animal production system, the better the choice arguably as it represents more efficient transfer of those nutrients as well.
So, options like salmon and chicken being fed anchovies and wheat, represent much better options than feeding pigs and cattle those same feed ingredients for that same reason, and the reality is that throughout the world we still do use fishmeal (anchovies) and wheat in feeds for pigs and cattle respectively. In many cases the alternative option of wasting valuable fish resources or valuable grain resources, though bioenergy (bioethanol/ biodiesel) or fertiliser represents a much worse scenario. In those cases, the nutrients are completely lost from our feed-food-chain. So maybe next time you eat some salmon, chicken or even beef just remember you are helping connect the feed-food divide and ensuring we don’t waste valuable nutrients. And probably enjoying it more than what the alternative option might have been as well.
As the world grapples with the urgent need to safeguard its oceans, the Monaco Blue Initiative (MBI) continues to serve as a beacon of hope, catalysing action and fostering collaboration towards a more sustainable future for our planet’s most precious resource
The discussions at Monaco Blue Initiative (MBI) 2024 cantered around key themes such as ocean protection, governance, the blue economy and the role of the private sector.
In addition, it discussed the challenge by the Mediterranean in achieving its 30x30 target; a target that refers to the 195 countries that make up COP15 signing at the end of 2022, the 30x30 agreement, which aims to protect 30 percent of oceans and land by 2030 and ensure that at least 10 percent of these areas have strict protection.
The day-long meeting in the Monaco Oceanographic Museum heard of success stories and lessons learned with updates being provided on international discussions concerning deep-sea mining, the plastic treaty, fisheries subsidies and upcoming ocean conferences.
The MBI, a platform for ocean conservation and governance, convened for its 15th edition in mid-March 2024.
This annual event, under the patronage of HSH Prince Albert II of Monaco, invited representatives from governments, international organisations, civil society, NGOs, the private sector, the scientific community along with the media to deliberate on the challenges facing oceans and to foster a sustainable blue economy.
In its digital report following this year’s event, the MBI outlined a program that comprised keynote speeches, panel discussions and updates on international initiatives related to ocean conservation and governance.
International Aquafeed reports here some highlighted statements from presenters that relate to the overall objective of conservationists, but also hinting at the role private investment,
including that from the aquaculture sector, could undertake to assist in meeting the challenges being faced; particularly in the area of funding and stewardship which many of the sustainable aspects and visions-for-the-future of the world’s oceans will come to rely upon.
Highlights from each of the keynote presenters, as reported by the MBI in its post-event press release, include:
1: No longer powerless …
“We are no longer powerless in the face of the degradation of the planet. We have the knowledge gained from our experience, new tools and greater resources. It is this knowledge, these tools, and these resources we will be talking about today. We will be doing so by examining the prospects offered by the blue economy and through it, the role of the private sector in ocean protection. We will be doing so when discussing the protection of the Mediterranean Sea and the achievement of the 30×30 target, and when looking at the more specific challenges of a future Treaty to combat plastic and the strict regulation of deep-sea mineral exploration.” says HSH Prince Albert II of Monaco in opening the 15th edition of the MBI in Monaco
2: The oceans can provide food …
“One of the major solutions to the climate crisis are the oceans, because the oceans can provide food for human and animal species, can provide substitutions for plastics and fertilisers, can provide innovative medical developments, can restore biodiversity, can protect the coastal communities that are threatened by the decline of fish stocks.
To do that, you need a multi-dimensional approach, changing the economic model, developing the renewables, but also looking
to the oceans,” says the Minister of Economy and Maritime Affairs for the Republic of Portugal HE Antonio Costa Silva.
3: We gather here as guardians …
“If we are all here, it means that we assume the roles and responsibilities which are important in achieving global objectives in the conservation and preservation of our world’s marine ecosystems. As we gather here as guardians of our beautiful and rich oceans, we cannot refute the fact that we are still concerned by the urgency in regard to their proper protection and governance. Globally, when it comes to marine protection we should, claim some important successes (.) the Biodiversity Beyond National Jurisdiction Treaty (BBJ) which our Parliament proudly ratified … making us the first country in Africa and
Honourable Minister Designated Minister for Fisheries and Blue Economy for the government of the Republic of the Seychelles, Jean-Francois Ferrari.
4: We are all in the same boat …
“We need to realise that we are all in the same boat. And the key word here is ‘collaboration.’ In particular ‘cross sectoral collaboration.’ To create synergies with all stakeholders involved in the blue economy sector and to discuss transparently at all levels - at the local, the regional, the European and the global level. At the same time, we need science ... to develop realistic solutions. This approach fosters innovation, resilience and collective action and ensures the necessary balance between economic prosperity and environmental conservation. It is a

The UN’s SDG 14 - ‘Live under water’ – vastly underfunded
incentives, facilitate and promote such discussions” says keynote presenter HE Christos Stylianides, Minister of Maritime Affairs and Insular Policy, Hellenic Republic, Greece.
5: The role of the private sector is decisive …
“We need public investments to address the scope. But we need private investments to reach the scale. To mobilise more private investment, the EU is blending public funding with private finance. The role of the private sector is decisive in driving the transition towards a sustainable blue economy, which ultimately aims to improve the health of our ocean. Both the public and private sectors are crucial in shaping the future of a more sustainable, regenerative and resilient blue economy,” says the Director General, Directorate-General for Maritime Affairs and Fisheries European Commission, Ms Charlina Vitcheva.
6’: Life below water’ is vastly underfunded …
“Promoting a blue economy based on sustainable activity, thereby ensuring the well-being of populations and ecosystems, is absolutely essential. This is especially important given the lack of funding. For example, among the United Nations’ Sustainable Development Goals, number 14 dedicated to ‘Life below water’
is vastly underfunded: funding amounts to around US$25 billion a year, whereas the needs are estimated at US$175 billion a yearseven times more!” adds Robert Calcagno, the CEO of Monaco’s Oceanographic Institute
7: The real game-changes is system change …
“Developing disruptive business models and blue-finance tools is vital for the transformation of the ocean economy, but the real game-changer is system change. The path towards system change could incorporate a human-centred, equitable and resilient ocean economy that delivers on both sustainability and commercial criteria, a regulatory framework that is clear but also simple enough for thriving ocean business based on pre-competitive data-sharing and collaboration based on trust,” says Olivier Wenden, the CEO and Vice-President of the Prince Albert I of Monaco Foundation.
The MBI, established in 2010 by HSH Prince Albert II of Monaco, is co-organised by the Oceanographic Institute, the Prince Albert I of Monaco Foundation and the Prince Albert II of Monaco Foundation. It serves as a platform to promote dialogue, collaboration and concrete action towards the protection of the marine environment and the development of a truly sustainable blue economy.

Over the past 15 years, insect ingredients have evolved from a little-known concept to a proven aquafeed component. Increased recognition of their value is due to a number of challenges being solved, and real-life success stories providing solid substantiation for their use. At the 2024 North Atlantic Seafood Forum (NASF) an illuminating discussion between eminent experts and the audience took place about how insect-based nutrition is low-hanging fruit for a low-footprint aquaculture industry. The conclusion? Now is the time to step in with a collaborative approach to create applications and a roadmap to secure supply.
A growing sense of urgency for sustainable solutions is becoming apparent as well as different sustainable initiatives. Some initiatives are prompted by the upcoming deadline of the European Green Deal and the accompanying EU Taxonomy,
aiming for a 55 percent cut to EU greenhouse gas emissions by 2030. Others are motivated by the chance to lead in meeting evolving consumer preferences and to bolster reputation by shrinking environmental footprints. Numerous retailers for example are taking steps to address scope 3 emissions to reduce their environmental impact and enhance their reputation with the increasingly environmentally conscious consumer.
This heightened focus on sustainability is also underscoring the importance of reducing the environmental footprint of the aquaculture sector.
CO2 emissions from feed account for 57 percent of the aquaculture total, according to the science journal Nature. The independent research organisation Stiftelsen for industriell og teknisk forskning (SINTEF) says the share for Norwegian farmed salmon is even larger, at 83 percent. Considering that feed is the largest contributor to CO2 emissions in aquaculture, it is essential to prioritise efforts to mitigate its environmental impact.
Some retailers have already taken proactive steps with regard to
aquaculture feed. In April, Dutch retailer Albert Heijn introduced shrimp in its stores that are fed with a lower-footprint feed. The company aims to halve the ecological footprint of fresh and longlife products chains by 2030. In collaboration with value chain partners Klaas Puul, Nutreco, Veramaris, and Protix, Albert Heijn spearheaded the development of this more sustainable feed based on insect meal and algae oil.
Insect ingredients: a proven solution
Insect ingredients, particularly black soldier fly (BSF) ingredients, have established themselves as a working aquaculture feed solution. The low footprint of the black soldier fly has been proven in a Life Cycle Analysis (LCA) conducted by the renowned German Institute of Food Technologies (DIL) on high-quality insect meal (ProteinX) and insect fats (LipidX) from Protix. Compared with fishmeal, insect ingredients produce 28 percent fewer CO2 emissions and release 86 percent more land for nature.
Multiple studies have shown black soldier fly ingredients to be safe and compatible in aquafeed formulations, as was highlighted by Erik-Jan Lock, Research Director at Nofima, at the NASF. This is endorsed by the industry representatives at NASF who participated in a Mentimeter survey, with 40 percent even stating that the environmental performance of insect ingredients makes them more compatible than other feed ingredients.
Insect ingredients are not just a technically viable solution. Over the last years, the insect industry has addressed a number of challenges to come up with a feasible commercial offer. Part of the solution lies in upscaling supply for which insect ingredients company Protix, as an example, has been preparing. Protix has been operating a factory at industrial levels since 2019. With this facility, the company has been uniquely positioned to perfect its insect solutions to satisfy feed manufacturers’ needs and prepare for a robust upscaling of its operations.
Investors have recognised the readiness of players in the insect sector. Investment in Protix by the European Investment Bank and a joint venture with industry giant Tyson Foods mark milestones for the industry and allow the sector to expand rapidly.
Thanks to the pooling of scientific insights, technological advancements and heavy investment, the insect industry is now well-positioned to deliver consistently high-quality ingredients in larger volumes. The Mentimeter research conducted at the NASF event shows that the 84 percent of survey respondents have insect ingredients on their agenda and see the solution’s potential.
But although the larger-scale production of insect ingredients in a consistently high quality is rapidly becoming a reality, there are still steps to be taken to exploit the full potential of insect
ingredients in the aquafeed industry. Two clear areas emerge from the responses of the Mentimeter audience:
1. Collaboration between the insect and aquaculture industries to showcase successful applications
2. Attraction of further investment through a clear roadmap with clear long-term commercial benefits
To address the first point, Protix calls out to innovative feed manufactures to connect and develop applications together. There is a plethora of (ongoing) research underpinning the potential health benefits to fish and shrimp. While a huge body of evidence supporting insects already exists, there are still potentially very attractive economic benefits to be realised. This is where feed manufactures and insect companies need to pull together, develop applications with potential health benefits, and share success stories. First moving feed manufacturers enjoy the benefit of an enhanced reputation and the whole sector could benefit of a comprehensive set of data proving long-term commercial benefits. At the same time, feed manufactures and insect companies should work together on a joint roadmap to hand-in-hand grow demand and supply in the sector. This way, both sectors can grow responsibly and attract further investments.
With insect products now available internationally on a commercial scale, the time is ripe for insect ingredients in aquafeed to take off in a responsible way. As pioneers in what was a fledging industry, Protix remains at the forefront of bringing insects into the mainstream. Insect-based feed will truly become mainstream if the aquaculture value chain collaborates with insect ingredient companies such as Protix to secure demand for new production capacity and attract further investment. Now is the time for cross-industry collaboration to create lasting change that will benefit producers, consumers and marine life.

Over the last decade, we have seen a significant growth of the global shrimp industry. Total imports in 2022 were 3,248,338 tonnes (Van der Pijl, 2023), with additional production in China estimated at 1,487,501 tonnes (Fu-Chi, 2023).
China and Vietnam (total 945,791 ton) and the US (837,622 tons) absorbed most of the growth in shrimp production. Ecuador has seen a compound annual growth rate (CAGR) of 17 percent from 2012 to 2019 and a very significant CAGR of 25 percent from 2020 to Q2 2023 (Villarrea, 2023).
Today, shrimp production is challenged by several problems that affects its’ growth worldwide. A Global Seafood Alliance 2022 survey that was presented to industry stakeholders mentions the most relevant challenges as: feed cost, market prices, diseases, and broodstock quality (Nikolik, 2022). Therefore, understanding the main environmental, nutritional, and operational factors that affect shrimp health may support the global efforts for promoting sustainable shrimp aquaculture.
Among the challenges mentioned above, shrimp health has the dramatic effect on the global industry. Asche (2021) evaluated the impact of disease outbreaks on the shrimp industry and concluding that the presence of disease increases the breakeven price significantly, and thereby increases the probability of losing money as well as increasing the risk.
To meet the growing consumption demands of the future, the focus on shrimp health is increasing, and more specifically how optimizing the functions of the gut can produce a more healthy, robust and profitable shrimp.
The shrimp digestive tract, and the digestive tract of that of all Crustacea, is made up of three sections (Holt, 2021). The foregut, containing the oesophagus and the two chambered stomach; the midgut; which begins at the junction of the hepatopancreas and traverses the length of the cephalothorax and the majority of the abdomen; and finally; the hindgut, containing the rectum and anus. These regions of the gut differ in their cell structure and function (Ceccaldi, 1989).
For shrimp, a healthy gut comprises various elements which include a robust intestinal structure and morphology, and efficient production of digestive enzymes. This allows optimal digestion and absorption of important nutrients. Also, an active non-specific immune response will promote the ability to eliminate invading pathogens such as viruses, bacteria and fungi, improving survival rates and productivity. A balanced intestinal microbiota can support the shrimps’ ability to survive, grow, and develop.
The benefits of a healthy gut in shrimp aquaculture:
The digestive tract is responsible, for many animals, and crustaceans in particular, for the nutritional function (Ceccaldi, 1989). This function includes ingestion, transit of nutrients, mechanical digestion, chemical and biochemical hydrolysis, cellular absorption, and transfer of excreta in the digestion tract. The lumen of the digestive tract is considered to be exposed to the external environment. The lateral wall of shrimp digestion tract is covered, in its fore and hind parts, with complexes of chitin and proteins which are removed at each molt with the exoskeleton. Another original aspect of the shrimp digestive tract relies on the fact that most reserves of the animal are accumulated here, and they are utilised at each inter-molting cycle. Optimal digestion and absorption of nutrients can lead to improved Feed Conversion Ratio (FCR), yield and better growth performance.
The shrimp non-specific immune system employs several hemolymph-borne factors in its fight against infection (Sis, 1992). Most of these factors are inducible, although they have no specific activity or memory. These factors serve to immobilise and agglutinate invaders as well as to sensitise them to phagocytosis. Both hemagglutinins and bactericidins have been identified in shrimp hemolymph. The agglutinins are protein molecules which play a role similar to that of antibodies. They also serve as opsonins and display some degree of binding specificity. Studies have also identified lectins involved in the immune response. These inducible hemolymph components are absorbed onto the surface of gram-negative bacteria where they enhance phagocytosis and the production of bacteriolysins and agglutinins. The carbohydrate receptors to which they bind are common ones, explaining their nonspecific response. Optimising the non-specific immune response in shrimp can reduce the impact of disease challenges and ultimately improve survival rates, and therefore, production yield.
A function of gut epithelial cells is to act as a physical barrier against pathogens, and a healthy gut is composed of epithelial cells that are tightly joined together to form a protective layer.
A healthy gut microbiome plays a crucial role in shrimp immunity by competing with pathogenic bacteria for space and nutrients, producing
antimicrobial compounds, and modulating the immune system mainly by stimulating the production of antimicrobial peptides, enhancing phagocytosis, and regulating inflammatory responses.
The gut-associated lymphoid tissue (GALT) contains immune cells, such as lymphocytes and macrophages, which are responsible for detecting and eliminating pathogens.
The gut plays a multifaceted role in shrimp immunity, encompassing physical, microbial, and immunological aspects. Maintaining gut health through proper nutrition, environmental management, and disease prevention strategies is essential for promoting shrimp health and productivity.
In response to the global increase of intensive shrimp farming, the shrimp feed industry has been developed using several strategies (Mansour, 2022). Among these strategies, feed additive supplementation is one of the most important industries that has gained great importance for several shrimp species as growth promoters, immunity enhancers, and an alternative strategy for fighting disease (Sharawy, 2022). Common feed additives are astaxanthins (Goulin, 2024), β-glucans (Huifeng, 2019), organic acids (Wangquan, 2017), probiotics (Bacillus subtilis) (Zokaeifar, 2012) and many other natural herbs like rosemary, oregano and essential oils.
Among the natural feed additives, saponins are one of the major groups that are used in the last decades of shrimp culture. Saponins, widely found in plants, contain either a steroid or triterpenoid aglycone to which one or more sugar chains are attached (Oda, 2003). In addition, saponins have the potential to act as prebiotics by influencing gut microbiota and promoting the
growth of beneficial bacteria (Hierro, 2008).
Saponins as beneficial additives
Saponins from the Quillaja saponaria tree and Yucca schidigera plant have been shown to have immunomodulatory, anti-inflammatory and antioxidant properties and may help to modulate the intestinal microflora. In addition, these specific saponins can increase cell membrane permeability, activate digestive enzymes and improve protein retention. Bo-Kun (2008) showed that Pacific White Shrimp (Liptopanaeus vannamei) that had been immersed in seawater containing 0.5 mg/l saponin showed increased resistance against Vibrio alginolyticus with a concomitant increase in phagocytic activity and clearance efficiency to V. alginolyticus. Martínez -Cordova (1998) evaluated the effects of Pacific white shrimp fattening rations containing Yucca schidigera extract, concluding that the additive has a positive effect in the quality of the water as well as in the production of the shrimp.
In addition, Hernandez-Acosta (2016) tested the inclusion of Yucca schidigera and Quillaja saponaria extracts in juvenile shrimp (L. vannamei) feeding with up to 2.0 g of saponins per kg of feed. The final average body weight and feed conversion ratio from shrimp feeding with 1.0 and 2.0 g of saponins per kg of feed had a significant improvement compared to other treatments.
PAQ-ProtexTM –a natural feed additive
Sourced from specific species of Quillaja saponaria trees and Yucca schidigera plants, PAQ-Protex is a hundred percent natural nutritional specialty product, a proprietary blend of triterpenoid and steroid saponins and polyphenols, also known as flavonoids. However, not all saponins are the same. The saponins and polyphenols in PAQ-Protex have been shown to produce meaningful changes in the digestive tract, supporting optimal gut health and immune function in shrimp and fish.
Increasing the gut surface area and activating digestive enzymes such as lipase and protease can lead to increased nutrient absorption, feed efficiency and production yield.
Moving to intensive shrimp cultivation requires optimal design of the culture system: origin of the post larvae’s, biosecurity, water quality, operations, feeding, feed quality and functional feed additives. The challenge for the shrimp in these intensive conditions is to maintain optimal health status through good gut health. By adding PAQ-Protex, these goals can be achieved – improving the guts’ ability to function in the digestive track, and in addition, supporting immunity to maintain a good health status.

Aquaculture is a complex industry with multiple variables that strongly impact its performance. Among these, sources of stress, disease outbreaks and occurrence of new pathogens such as parasites are a huge threat.
Enterocytozoon hepatopenaei (EHP) is a microsporidian parasite that was first characterised in the black tiger shrimp Penaeus monodon in 2009 in Thailand. EHP is restricted to the shrimp hepatopancreas (HP) and its occurrence was usually given scant attention because of the overwhelming focus on some other diseases, such as early mortality syndrome (EMS) and white faeces syndrome. However, although EHP does not appear to cause high mortality, it is associated with severe growth retardation and depressed feed conversion ratio (FCR) in shrimp, leading to economic losses for the farmers who may need to resort to an early harvest.
To date, no reliable and sustainable solutions have shown real efficacy on the reduction of impact of EHP in shrimp. The aim of the current research at miXscience (France), is to design a specific solution against EHP in shrimp aquaculture. Efficacy was demonstrated from the laboratory to the field, focusing on the reduction of germination of EHP spores and its associated effect on shrimp performance. Complementary studies have been performed to explore, by
microscopy, the fine mechanisms of action of the solution and demonstrate how this new product disturbs the EHP spores.
The life cycle of this microsporidian parasite can be divided into three phases: the infective, the proliferative and the sporeforming phase (Figure 1).
Figure 1. Illustration of Enterocytozoon hepatopenaei (EHP) infestation cycle.
Adapted from Chaijarasphong et al., 2021
The infective phase is the only phase that can survive without the host since spores are outside of the host’s cells in a dormant and more resistant form. Once in the host, the dormant spore will become an infective one through the key phase of the cycle: the germination. This phase is notably marked by the expression of an essential tool for the spore to replicate: the polar tube.
Thanks to it, the germinated spore will puncture the plasma membrane of the host’s cell, releasing sporoplasms (infectious material) inside the cytoplasm of the cell. The sporoplasms start to replicate in many copies which are released into the environment after killing the cells, and eventually infect other shrimps.
Since EHP has an internal phase during which spores enter host’s cells, it is important to ensure that the parasite is inhibited from host cell entry during its external phase when spores are free, non-protected and before the emergence of their polar tube. This is a fundamental point when deciding on recommendations for application of this new biosecurity tool.
Laboratory and field trials demonstrated that a feed solution (A-Coverost, MiXscience) based on an innovative blend of oleochemicals associated to a specific active matrix (Figure 2) significantly reduces the capacity of EHP spores to germinate and express the polar tube directly linked to their capability to be infective. This effect clearly impacts the final EHP load in hepatopancreas, impacting the whole infection dynamic in the pond/farm and helps to maintain good shrimp performance to reach commercial sizes.
At the laboratory scale, the EHP spores used were purified according to a standard protocol developed by the center (Aldama-Cano et al., 2018). The purified spores were aliquoted and incubated with the experimental product (A-Coverost) for 30 minutes at room temperature (27°C) in Eppendorf tubes and a total volume of 1mL per reaction. The effect of the product on germination and spore viability was measured by microscopic observation after a staining step with phloxine. The germination rate or percentage of spore extrusion was calculated from the number of spores extruded (or germinated) out of the 100 spores observed.
Results showed that A-Coverost significantly reduced (>60%) the germination rate of EHP spores. It has been expressed by a lower expression of polar tubes visible under microscope. This trend has been observed in the two consecutive trials demonstrating a certain robustness of the efficacy of the product (Figure 3).
Complementary studies involving scanning electron microscopy (SEM) coupled with epifluorescence microscopy (and in

Figure 3. Germination rates of spores (%) – Results from two consecutive tests with two different EHP batchesparticular with markers of cellular integrity and viability) demonstrated the fine mechanisms of actions of the products to explain how the it disturbs the EHP spores and their germination.
These involved the evaluation of the direct effect of A-Coverost tested at 2, 4, 6 and 8g/L on EHP purified spores. Monitoring by SEM allowed us to understand the impact of the product (tested at different dosages) on the morphology of the spores, their ability to germinate and therefore their potential in infecting shrimp. In parallel, a marking with acridine orange (AO) and propidium iodide (PI) was implemented to measure the impact on spore viability.
Acridine orange (AO) is a red/orange-fluorescent dye used in epifluorescence microscopy and flow cytometry. When AO is used, it helps to detect DNA denaturation or to detect DNA damage (Darzynkiewicz et al, 2004 and Evenson et al, 1980).
Propidium iodide (PI) is a red-fluorescent dye. The use of PI is not exclusive only to live cells, it is also commonly used to detect dead cells in a population. Propidium iodide is used as a DNA stain in flow cytometry or epifluorescence to evaluate cell viability. Propidium Iodide is not membrane-permeable, making it useful to differentiate necrotic, apoptotic and healthy cells based on membrane integrity (Suzuki et al, 1997).
The EHP spores used were purified according to a standard protocol developed by the center (Aldama-Cano et al., 2018). The active purified spores (1x107 spores) were mixed with A-Coverost at the final concentration of 8g/L. The solutions were incubated for 120 minutes at room temperature (25-26°C), before being subjected to centrifugation at 10,000rpm for 5 min.
The treated spores were washed twice with 1X PBS (phosphatebuffered saline) and 10 µL were placed on a round coverslip which were then placed in a 24-well plate and allowed to air dry. The dried coverslips were fixed with 2.5% glutaraldehyde in 0.1M buffer incubated at 4°C overnight. Treated spores on coverslips were washed twice with 0.1M PB for 10 min each and fixed with 0.1% osmium tetroxide in the dark. Spores were washed twice with 0.1 MPB for 10 min and dehydrated with alcohol in series, drying with liquid CO2, and spray coating with gold. The morphology of EHP spores was examined using a Hitachi SU8010 scanning electron microscope.
Acridine orange (AO) and PI were diluted in PBS. The two products were mixed at a ratio of 1:1 and 3μL of AO/IP mixture were mixed with approximately 20μL of spore sample. The solution was placed on a slide then analyzed under an epifluorescence microscope
The In vitro results indicated the following bullet points :
• The A-Coverost product interacted with the membrane of EHP spores, causing disruption; abnormal morphology of the spores was observed and they were no longer able to germinate (which confirmed our previous results) and tended to clump together (Figure 4).
• The A-Coverost product induced a loss of sealing of the spores, which involved the marking of the DNA with PI and therefore a reduction in the viability of the spores. We observed a very marked dose effect with an average mortality of the spores of 73% when they were exposed to a dose of A-Coverost of 4g/L and a mortality of 95 and 97% when the spores were respectively exposed with doses of 6 and 8g/L (Figure 5).
In vivo results
Based on the previous results, the product has been tested directly in shrimp to confirm its observed potential at lab scale.
Experimental shrimp studies were performed at the BIOTEC facilities (Thailand) and at SHRIMPVET facilities (Vietnam). Following the laboratory tests, the experimental product A-Coverost was incorporated either by top coating or directly during the pelletising process. The recommended dose was 4 kg/ tonne of feed for both applications.
The trials were set up as a completely randomised designs in which two groups (Challenged CTRL and Challenged A-Coverost) were compared (Table 1). Each tank contained at least 200 shrimp with an initial weight of about 3g (water volume 320L; salinity 20ppt) and shrimp were pre-fed with the indicated feed for a pre-feeding period of seven days. On day 7 of feeding, 12 shrimp from each group were collected for the detection of EHP level by qPCR. Each group had three replications.
Shrimp hepatopancreas was collected individually from 12 shrimp per tank for DNA extraction. DNA template for qPCR was obtained by homogenising hepatopancreas tissue in DNA lysis buffer (Munkongwongsiri et al., 2021). The 20µL of qPCR reaction mixture contained 1x SYBR green-qPCR, 0.2 µM SWP primers and 10ng of DNA template. To calculate the EHP load, the samples were compared with the standard obtained from plasmid DNA
a concentration of 1.0x106 copies/µL.
The shrimp growth performance indicators including initial weight, final weight, weight gain, average daily growth (ADG), feed conversion ratio (FCR) and survival rate were determined.
at Figure 4: SEM study of the impact of A-Coverost on the germination and morphology of EHP spores
The in vivo results indicated the following bullet points :
• The shrimp trials, carried out from 2021 to 2023, notably with EHP cohabitation approaches (EHP infection by cohabitation model (Salachan et al., 2017)) confirmed the effect of the product under different contexts and breeding conditions: country, Vietnam versus Thailand; shrimp genetics; EHP strains; food, pond conditions, etc.
• A-Coverost, applied at 4 kg/tonne of feed, has the same efficacy when applied directly by pelleting or indirectly by top coating (Figure 6).
• Based on the cycle of infection of EHP, the preventive approach remains our recommendation to ensure that spores are killed or inactivated during their free phase out of the hepatopancreas cells. The sooner is the application, the better is the result. Our trials showed that it’s more pertinent to apply
After the pre-feeding period, shrimp from each group were transferred to three aquaria with 35 shrimp each (water volume 30L; salinity 20ppt) and placed into three cohabitation tanks (water volume 300L; salinity 20ppt) for induction of EHP infection by cohabitation model (Salachan et al., 2017).
A number of 10 EHP heavily infected shrimp, determined by a nested PCR method were added into the challenge tanks. During cohabitation, shrimp were continuously fed with the indicated feed formula. On day 17, 12 shrimp per basket were collected for the detection of EHP level by SWP-PCR.
Experimental timelines are described in Table 1.
The shrimp trials confirmed the ubiquitous potential of the product to control EHP infestation in shrimp.
We understand that a direct interaction between the product and the EHP spores during their extracellular phase is a prerequisite to initiate the inhibition process and to kill the spores. This will slow down the whole dynamic of infection to control the EHP load and allow the shrimp to reach commercial sizes.. Prevention remains/ is then the key approach.
However, it is clear that a single solution is not sufficient to fully eradicate EHP occurrences.
A-Coverost needs to be used as a tool in a complete management program based on biosecurity practices to implement at the farm level in order to limit the presence of the
We are a point where we need to rethink our food system globally and the impact it has on the environment. Today, sustainability is an imperative that companies need to fullfill rather than an option. There are a few many models the industry follows to minimise the impact it has on the nature One such model is circular economy. The circular economy model for food products focuses on the reuse of “waste” byproducts, such that the valuechain outputs become inputs for other value-chains. For example, fish processing produces fillets as well as leftover scraps, skins and trimmings of fish. These scraps can then be used as ingredients in pet feed. The circular economy also encourages valorising byproducts that might otherwise be disposed of and reusing or recycling other items at the end of their useful life.
Norway based feed company biomega® is a key player in this field. Biomega Group AS (biomega®) is a producer of premium Norwegian salmon-based innovative ingredients, both for premium petfood and human nutrition. biomega®’s business model is fully sustainable and uses proprietary biotech to transform high quality raw material into premium food and petfood ingredients. In its modern food grade biorefineries, biomega® produces salmon oil and peptides using continuous enzymatic hydrolysis. biomega®
continuously invests in R&D to ensure best-in-class technology and respond to customers’ needs, including traceability and sustainability.
The cornerstone of their approach lies in the gentle enzymatic hydrolysis process, which preserves the integrity of nutrients while ensuring precise separation of components.
“Our philosophy is centered around treating raw materials with utmost care, employing low temperatures and enzymatic reactions to achieve optimal results,” Stig Petersen, CEO of biomega®, explained. “Whether it’s salmon offcuts or visceral parts, our goal is to maximize the nutritional value through meticulous refining. It is critical to get the off-cuts and viscera into the biomega® production cycle as quickly as possible so that they remain fresh. This will ensure the limited degrading of the natural quality of the ingredients.”
“When we investigate the rest remains of salmon, it has a matrix consisting of protein structures and bones that hold the fats. Some of these proteins are water soluble, and some are not. Those that are water-soluble can be separated and when concentrated you have a liquid fraction featuring 60 percent of these proteins. This is very easy for an animal to digest while offering a nutritional boost, coupled with a good taste and smell that will stimulate appetite. We are doing some studies in partnership with the University of Illinois, where we will be looking at the specific impacts on animals using
these products, in comparison with other sources”, he explains.
Petersen elaborated on the customisability of biomega®’s reactors, which are tailored for specific uses and maintain strict control over the refining process. This attention to detail not only ensures product consistency but also underscores biomega®’s commitment to quality and precision.
In addressing sustainability challenges, Petersen outlined biomega®’s multifaceted approach, which includes decentralised production facilities to minimise transportation emissions and a concerted effort to utilise as much of the fish as possible for human consumption. By upcycling fish byproducts and focusing on resource efficiency, biomega® aims to reduce its carbon footprint and contribute to a more sustainable aquaculture industry. Along with this, biomega® takes pride in how they handle their raw materials as well.
Petersen elaborates, “We have designed production, that we now have proven, can be positioned at different locations. So instead of moving all our raw materials to one main factory, we have now set up a factory where we have a sufficient volume of raw material available within a few hours’ transportation. That is supposed to control quality, but also that we reduce the road transportation and energy to remove water.”
The company delivers high quality products to the aquaculture, petfood and human nutrition sectors. biomega® produces and sells salmon peptides and collagen in powder form and salmon oil in liquid form under trade names SalMe Peptides, SalMe Collagen Peptides and SalMe Salmon Oil for human nutrition, and liquid and powder products under the Salmigo® brand name that are high in protein for the petfood market.
At PCE, precision engineering meets custom design to produce dies that fit all pellet press models. Our dedication to quality ensures your operations are seamless, efficient, and high-quality. Our dies are essential for top-notch performance in feed, biomass, or any material pelleting.
Moving the salmon through the value added process
biomega®'s patented enzymatic hydrolysis process
biomega® was founded in 2000 on the premise of advancing innovative biotechnology to release the full nutritional and functional value of side streams from the salmon industry. And later in 2002, it built the world’s first biorefinery with its patented continuous enzymatic hydrolysis process in a building owned by Sekkingstad AS and in 2012, they build their own factory next to it. Later in 2021/2022, they opened their new biorefinery in Hirtshals, which was built with a focus on energy efficiency and with the potential for industry symbiosis among the surrounding production sites in mind.
“Due to our new facility being a first-of-its-kind biorefinery and the knowhow we have in biomega®, the project received funding from the European Union’s LIFE Programme for Environment and Resource Efficiency under the name Life Conquer. Through this, we have committed to ambitious environmental goals on
bio-waste reduction, energy reduction and water efficiency”, says Petersen. biomega® sources fresh raw materials from the Norwegian salmon farming industry. More than 90 percent of the Group’s production in 2022 was exported to Europe, North America and Asia.
The manufacturers of pet and human food must constantly consider sustainability when developing new products since aquatic life suffers and improved practices and grow sustainability. While most companies in our industry focus on making the upstream supply chain more sustainable, both feed and food companies have to find ways to guarantee that any raw material is utilized to its utmost for human consumption followed by pet food and aquafeed looking into the utilization of the consequence products from the primary production. wasted.

Mediterranean aquaculture in open-net pens is dependent upon a set of demanding management practices with fish, which are also often exposed to infectious and non-infectious deleterious factors and abrupt environmental fluctuations. These successive insults exacerbate the risk of cumulative damages and disease — often resulting in lingering poor performance without clear treatments or diagnostic protocols. In addition, optimizing growth performance and feed efficiency is crucial, particularly in the context of increasing costs of raw materials.
Functional feeds are widely used as preventive strategies to optimise farmed fish health and performance. Ultimately, this positively contributes to the volume, cost and quality of the harvest. Backed by decades of successful application in aquaculture yeast cell wall (YCW) products demonstrate some of the most sweeping benefits, particularly within the diverse landscape of functional ingredients. A new player in this category, Optiwall, shows promising results in European seabass according to a new performance trial.
application, it is essential to go further than the MOS and β-glucans levels and deploy a well-documented product with a consistent manufacturing process and certified origin from a specialist provider. Optiwall is a novel YCW product from Lallemand Animal Nutrition, a leading producer and provider of microbial-based solutions for animal nutrition. The product originates from a single and specific yeast strain, manufacturing plant and production process. It is down processed by Lallemand to maximize the desired functionalities for the target application. The result is an affordable, consistent and effective product to support fish health and performance.
European seabass performance trial
A two-month trial was performed in Portugal in 2023, testing different levels of OPTIWALL supplementation in juvenile European seabass (starting bodyweight 11g; 22°C; 36 ppt) in quadruplicate.
A baseline commercial diet for juvenile seabass was produced (20% fish meal; 15% land animal and 32 percent plant material; 46 percent crude protein; 16 percent crude fat; 21 MJ/kg) and supplemented with OPTIWALL (Lallemand Animal Nutrition) at a dose of 0.0, 1.5, 3.0, and 4.5 kg/T feed, which were hand-fed to visual appetite over the trial’s duration.
Fish were first reared under ideal conditions for five weeks then chronically exposed to stressors for three weeks in the
YCW contains mannanoligosaccharides (MOS) and β-glucans, which, upon ingestion, are recognised at the gut level triggering a cascade of immune and homeostatic processes in support of gut function and integrity, fish health and performance. However, MOS and β-glucans are complex macromolecules that can widely vary in structure and properties depending on the strain and origin of the yeast product.
To reap the rewards from YCW

form of repeat handling (1 min. netting out twice weekly) and high-densitylow oxygen levels by reducing the tanks’ water level (Figure 1).
The study evaluated the diet’s effects on production performance and on the gut and skin responses over the ideal and demanding trial periods: Growth and performance were assessed at the end of each period
Specific biomarkers of gut immune response and protection were evaluated (faecal levels of calprotectin and mucins)
Gut and skin health and mucosal activity were assessed: skin mucus excretion was quantified, skin mucus quality was analysed for its anti-microbial property, and classical gut and skin histology was performed
The trial showed that specific growth rates and feed conversion improved with increasing intake of Optiwall; by up to 6.7 percent and 8.3 percent respectively over the trial duration with YCW 4.5 (Figure 2).
During the challenge phase, as expected, growth and FCR markedly deteriorated across all groups however, the loss of FCR was clearly mitigated in the YCW 4.5 group.
Calprotectin (CP) is secreted by white blood cells as a marker of immune activation elicited by stressors, tissue injury or microbial presence. It has beneficial properties at physiological levels (antimicrobial, oxidant scavenging and immune promotion) supporting gut barrier defence and integrity. Mucin is a constituent of secreted mucus, making it a marker of mucus excretion levels and an essential gatekeeper of mucosal protection and function.
Under the ideal phase of the trial, fecal CP increased with increasing YCW intake, indicating YCW detection and reinforcement of gut defences as supported by higher mucinlevels at the end of Phase I (Figure 3). This was verified at the end of the stress-exposure phase, when OPTIWALL was shown to potentiate increased gut mucus excretion in a dosedependent manner, as well as lower CP-levels indicating reduced

susceptibility and potential disturbance of the gut to the inflicted stressors.
As observed in the gut, skin mucus excretion increased with OPTIWALL intake in a dose-dependent manner (Figure 4). This was particularly marked following stress exposure (+37% excretion), when skin protection is most needed. Interestingly, the antimicrobial (lysozyme) activity of the mucus was also promoted by Optiwall when exposed to stressful conditions. However, at the higher dose tested, there was an apparent dilution of the antimicrobial activity related to the higher excretion level. Interestingly, in the group without supplementation (control), exposure to stress did not promote skin mucus excretion but tended to reduce its antimicrobial activity confirming the benefits of functional feed ingredients.
The new trial confirms the potential of the novel YCW Optiwall as an effective functional supplement to support seabass health (gut and skin robustness) and performance when supplemented continuously for 8 weeks. This was particularly marked under stressful conditions when OPTIWALL supported gut and skin defense mechanisms (mucus excretion and antimicrobial properties) at a time when it was most needed. In-feed incorporation can be selected between 1.5 to 4.5 kg/T feed depending on the level of protection and performance targeted.
Mediterranean seabass and seabream aquaculture have grown and intensified considerably in the last decades; but operations are exposed to ever-increasing biological risks and related costs.
In that context, evidence-based, preventive health solutions become an essential tool to help achieve the production target and schedule with minimal reliance on medication. As a yeast-based ingredient optimised for animal health and performance, Optiwall provides broad and cost-effective benefits in support of fish robustness and farm performance.

60 TECHNOLOGY SHOWCASE
This month, I thought I would focus on an aspect of aquaculture technology that is usually not mentioned: well boats.
A long time ago, I was working with a fish farmer in Indonesia who used well boats to transport his valuable fish from his farm in the Riau region, just south of Singapore, to the lucrative market in Hong Kong. The boats were rather primitive, small wooden vessels with one tank that was oxygenated during the transport to keep the fish alive. The technology was simple, but most of the time it worked.
About twenty years ago, I had my first encounter with modern well boats. I was part of a team that was given the task of counting fish in a salmon farm that was being sold. And of course, the number of fish and the size of the biomass was an extremely important factor that would determine the sales price. So we had to count the fish and weigh them. As an independent auditor my group was given the task.
So I spent 24 hours on board a well boat out on the farm off the coast of Norway, while all the fish was pumped out of the floating cage and into the well boat. The fish was sent through an automatic counter which also estimated the weight. In addition, I had to take a sample every hour and weigh it manually to confirm the result that the automatic counter gave.
It was an exhausting experience, because I had to work continuously for 24 hours until we had counted all the fish.
Well boats have seen a tremendous technological development through the years. That boat I worked on would today be regarded as a rather small and primitive vessel, for well boats are now large vessels with very sophisticated equipment on board. Well boats are used mainly in salmon and trout farming in Norway, Iceland, Scotland and Chile.
Today’s well boats have two tanks or “wells” in which fresh seawater is circulated. The water is circulated with the help of the boat’s speed through the water and intake at the front in the well where water is pushed in and valves at the stern where the water is pushed/sucked out. Salmon and trout can also be transported in a so-called “closed system”. This means that you do not circulate new water, but that the well is closed and the water is recycled using a pump system where oxygen is added to the water, which is very important for the fish. The fish’s oxygen uptake depends, among other things, on stress tolerance, water temperature, the water’s pH value and the concentration of carbon dioxide (CO2) in the water. In case of closed transport, it is important to vent
The Nor-Fishing Foundation
the CO2 that is formed. This is done using a separate system where the water is pumped up into an “aeration box” where the water is whipped up and CO2 is released. In Scotland, stricter requirements are placed on the well boats with regard to closed transports and boats with such technology are mainly used there. Closed systems have a lower risk of infection spreading.
The tanks in well boats usually contain between 15 and 18 percent fish. The rest of the volume consists of seawater. After January 2021, the water that is pumped in must be disinfected when transporting smolt and broodstock. In addition, the water must be disinfected when it is released when transporting food fish to another farm or to a slaughtering plant on land. The water on board well boats can, among other things, be disinfected with ozone gas.
While the primary use of well boats is to transport live fish from the hatchery to the floating cages, and harvestable fish from the floating cages to the slaughtering and packaging plant, well boats today have a number of other uses, for example when salmon is undergoing de-lousing. Previously, this was done by “dipping” the salmon in chemicals in one of the two wells in the vessels, but since 2022, de-lousing is done thermically or mechanically on board well boats.
In the beginning, wellboats were rather small, but today, the largest wellboat in use has a loading capacity of 7 500 m3, which means it can carry about 1 200 tonnes of fish. It is 83 meters long and 31 meters wide.
With very large offshore installations, large well boats are needed to transport the fish to processing on land, so even larger vessels may be needed in the future.

A collaboration between aquaculture technology specialists Ace Aquatec and start-up Tiny Fish is advancing Scottish salmon’s circular economy by helping the sector gain access to new premium food markets for its smallest fish.
Salmon raised at farms in Scotland achieve a monthly survival rate ranging from 97-99 percent throughout their lifecycle, with these fish losses being traditionally repurposed into compost or bioenergy. However, during the salmon’s freshwater phase (the first year after hatching), a selection of small salmon may be humanely removed from the population to allow for the best salmon to be raised at sea to a market size of about five kilograms. This selection of fresh fish in the hatchery phase provides an opportunity to market them as premium foods in many unique markets.
Tiny Fish harvest, collect, freeze, package and store the small salmon for value-added distribution channels at restaurants, hotels, takeaways, zoos, aquariums and petfood suppliers across the UK, making every fish count in the aquaculture industry.
To facilitate a humane, safe and efficient process to prepare small salmon for these unique markets, Scotland’s salmon farming sector has employed Ace Aquatec’s Humane Culling System (A-HCS). The A-HCS is a smaller and more portable version of the company’s awardwinning Humane Stunner Universal (A-HSU).
Amongst the partnership’s freshwater clients are seafood giant Mowi and Landcatch. Mowi has already seen positive outcomes for sustainability when some of their smallest fry and parr (salmon which are not yet at smolt stage) have been utilised for human consumption and petfood producers like Golden Acre Pet Foods.
The Tiny Fish and Ace Aquatec partnership has been shortlisted for the ‘Collaboration’ category at the Aquaculture Awards 2024. Winners will be announced in Aviemore on May 15. Tara McGregor-Woodhams, Chief Sales and Marketing Officer at Ace Aquatec, said: “The goal of this partnership of making every fish count is closely aligned with our own commitment to sustainability at Ace Aquatec. This collaboration has created a real opportunity for Scottish producers to show the global aquaculture sector that putting welfare and zero food waste at the heart of processing is easy to achieve and the right thing to do.”
Aquaculture Stewardship Council (ASC) joined scientists and policymakers from across Ghana, United Kingdom, Senegal, Sierra Leone and Nigeria at the One Health Aquaculture workshop held in Accra, Ghana to discuss the potential and benefits of developing responsible aquaculture across the region.
ASC Head of Improver Programme, Roy van Daatselaar joined the event to talk about how responsible aquaculture can drive and support the blue food initiative in the region.
Van Daatselaar said, “We are proud to support the Blue Foods Partnership (BFP) in Ghana and work towards the collective improvement of aquaculture as part of the responsible food systems.
“Ghana is a frontrunner in Africa when it comes to professionalising and transforming its local aquaculture industry. Through collaboration, investments and research, the potential to contribute to the regional food security agenda is promising. Responsible aquaculture is key in this vision and ASC is happy to support the industry in Ghana towards success.”
Stolt Sea Farm’s turbot facility in Oye, Norway is the first of its landbased fish farms to receive globally recognised sustainability certification from the Aquaculture Stewardship Council (ASC).
The farm was independently assessed against strict criteria and the certification confirms the sustainability of the operations and its turbot on growing facility.
The ASC – a global farmed seafood certification programme – recognises
The workshop was organised by the UK government’s Department for Environment, Food and Rural Affairs (Defra) Ocean Country Partnership Programme and their programme partner CEFAS, in collaboration with the World Economic Forum’s Blue Food Partnership Ghana Initiative with their leading local partner, the Chamber of Aquaculture Ghana.
The Chamber of Aquaculture’s CEO, Jacob Adzikah said, “The ASC meeting provided a unique opportunity for the members of the Chamber, Blue Food Partnership Ghana Initiative and other stakeholders to understand the ASC certification process, its benefits and its impact on sustainability. The presentation by the ASC team was excellent. This was one of the best networking events organised by the Chamber of Aquaculture.”
Some of the key issues that were highlighted during the workshop include environmental and social issues, as well as new technologies that can help in improving safety in aquaculture production and fish health management practices. The workshop also discussed how a Seafood Risk Tool can be applied to identify and manage chemical and pathogen hazards across the supply chain.
the need to promote responsible fish farming that respects fish, people and the planet.
Its standards for farms and seafood production are developed and continually reviewed in partnership with NGOs, academics, farmers, retailers and aquaculture experts.
Berta Fernandez, Stolt Sea Farm’s (SSF) Quality and Environment Manager, said: “The ASC is recognised across the aquaculture and retail industries as the gold standard for sustainability, so we are extremely pleased to have received this certification for our farm in Norway. Oye’s processes were assessed in great detail and achieving this credential confirms our commitment
Mowi’s law suit against Norwegian salmon production tax has been dismissed by Hordaland District Court, as per Norwegian news reports.
Mowi, world’s largest salmon farmer, sued the Norwegian government last year as they believe the law is in breach of the EEA rules and the four freedoms, including the free flow of capital.
“The district court has, in the state’s view, came to the correct result that the lawsuit from Mowi must be dismissed,” said Government Attorney Fredrik Sejersted, according to Norwegian newspaper E24.
to sustainable practices across our operations and in our interactions with local communities.”
Alma Román, ASC’s Market Development Manager in Spain and Portugal, said: “We would like to congratulate Stolt Sea Farm for achieving ASC certification for its turbot farm in Norway. This certification reflects Stolt Sea Farm’s commitment toward sustainable aquaculture and in promoting responsibility produced fish in European market and beyond.”
Stolt Sea Farm is currently working towards certifying the rest of its farms and remains committed to ensuring future generations continue to enjoy wonderful seafood.
The Sejersted added that Mowi will still be able to file a lawsuit at a later date when the company has received a concrete tax decision.
The new aquaculture tax plan, which came into effect on last year, makes its discretionary for salmon farmers to pay a basic rent tax of 25 percent on the profit from their sea-based farming activities, in addition to a 22 percent corporation tax. But this ground tax is applicable only to profits over NOK 70 million.
The deduction was introduced with a desire to protect the smaller players. In this way, the companies with the largest profits will pay the basic interest tax. At the same time, the deduction will also reduce the large companies’ tax base. In 2023 the company had a turnover of EUR 5.5 billion.
Ocean Ark, a patented advanced self-cleaning trimaran superstructure, was developed by Ocean Sovereign according to Marpol, Solas and IMO regulations. The vessel is designed with low density to operate in high offshore waters, drifting with the natural current and natural fish shoals. it is designed to ensure sufficient safety for the environment, fish and crew. The mobile nature of Ocean Ark will help to ensure the health and welfare of the fish and ensure that the fish are kept in their natural habitat. DNV, the independent assurance and risk management provider, has teamed up with Ocean Sovereign to obtain French registration for the deployment of this technology. Deploying the innovative Ocean Ark vessel away from marine heatwaves, algae blooms and storms – aquaculture’s three Archille’s heels – aims to increase fish welfare, produce higher quality protein, and increase world fish production without increasing pressures on fish stocks and coastal habitats.
Scotland is famed for its history of invention, with a long list of impactful technologies stemming from this part of the UK. From everyday items such as the television and telephone to the ground breaking science behind the cloning of Dolly the Sheep or the MRI scanner, we are a nation of innovators.
For key sectors - including the likes of energy, whisky production and aquaculture - technology developed here in Scotland has been a game-changer in terms of productivity and success. The wider world may be less familiar with some of these tools and techniques, but they are equally important for core industries that underpin thousands of Scottish jobs and contribute to economic growth.
Aquaculture, in particular, is a sector that has been built upon the outcomes of innovative research and development (R&D), and there is a steady stream of new products, systems and processes continuing to change our ways of working. There are a number of examples of technologies, initially developed to support Scottish seafood production, now making waves internationally with the potential to impact other branches of the blue economy, agriculture, life sciences and the environment.
Using deep learning AI, OTAQ has developed a system to automatically identify phytoplankton around marine aquaculture sites that could potentially result in harmful algal blooms (HABs). By providing critical and timely information, LPAS enables operators to make early and informed decisions on sitespecific mitigation strategies and actions.
Tritonia Scientific’s
The underwater imaging business is using ROVs linked to above-water GPS technology and acoustic transponders to capture digital images of the seabed. These images can be used to build an accurate 3D model that can show various physical characteristics and be used alongside advanced comparison software to monitor changes on the seabed in and around fish farms.
The Dundee-based technology company has created a lightweight camera system that uses a series of stereoscopic cameras supported by machine learning and AI to measure fish length and height and accurately estimate weight. It tracks multiple fish simultaneously, collecting significant amounts of data in a short period to support producers with decision-making.
and
Scotland has a thriving start-up scene, with entrepreneurship and new product development supported by a range of organisations, from business support agencies and funding vehicles to innovation centres. The Sustainable Aquaculture Innovation Centre (SAIC) has been at the centre of several key developments in recent years – including work with OTAQ and Tritonia Scientific, among many more. We have facilitated collaboration between sector experts and academics to solve critical challenges and take ideas one stage closer to commercialisation.
Other countries are beginning to see Scotland as an example of innovation best practice. Programmes such as the Blue Bridge initiative – aimed at Chilean companies looking to expand their operations and bring ground-breaking innovations to the UK –are a fantastic opportunity to transfer knowledge and technology breakthroughs. Trade events including Aquaculture UK and Aqua Nor also offer a valuable international stage on which to showcase Scotland’s success and share it with the wider sector and its supply chain.
However, as the speed of adoption of technology including advanced methods of collecting data, robotics, artificial intelligence (AI) and other devices only increases, we cannot afford to lose sight of the main reason for doing so – the ‘why’.
Last year the Scottish Government set out its Vision for Sustainable Aquaculture, illustrating a refreshed ambition for the sector. It recognises the important role of aquaculture in contributing to global food security and producing healthy, nutritious food for people in Scotland, and beyond, as well as its
place in supporting rural communities and protecting Scotland’s natural environment.
Perhaps the most important part of the vision is the renewed focus on high standards for farmed fish health and welfare, including disease prevention – ultimately, the sector’s success depends on healthy, happy fish.
Of course, technology fits in with that. It can be an enabler for increasing capacity or unlocking new methods of farming, but it must align with biology. Without looking at how technology may change fish behaviour or the conditions of the water around them,
it will not have the desired effect. Rather than technology being at the centre of the R&D conversation, it must first focus on the needs of our livestock and other marine life.
Just recently, SAIC announced a renewed focus on fish health R&D, delivered in collaboration between the private and public sectors and aligned to the Scottish Government’s 10-year Farmed Fish Health Framework. The goal is to build on the innovation achieved over the past decade and sharpen our focus on driving positive health and welfare outcomes for farmed fish.

There are various macro-economic and global factors influencing the future of aquaculture, which will likely shape the focus of R&D. From consumers’ increasing desire for sustainably sourced food and a shift towards a less meat-heavy diet, to the finite amount of land remaining for land-based farming, there are opportunities for aquaculture to grow in a way that satisfies the worldwide demand for protein responsibly.
Also among those factors is the regulatory and financial environment. Despite the impact it may have on our Norwegian counterparts, the introduction of new taxes for salmon producers in the country could in fact lead to new opportunities in other seafood-producing nations such as Iceland, the Faroe Islands and, of course, Scotland. With capital to invest, but new policies discouraging them from doing so, it could accelerate big companies’ drive for innovation in other places.
Large-scale projects are already underway, exploring new methods of seafood production such as offshore farming and near-shore contained production, which could both be beneficial for Scottish salmon producers. However, these types of ambitious projects must be supported with robust scientific evidence to reassure the sector and consumers of their impact on fish health and wellbeing, as well as by an agile and fit-for-purpose regulatory system.
By the end of 2030, SalMar Aker Ocean aims to sustainably produce 150,000 tonnes of salmon per year using offshore fish farms, making it one of the world’s largest producers of farmed salmon. Originating in Norway, but with the potential to be rolled out in other countries, the technology is founded upon SalMar and Aker’s decades of expertise in the fields of salmon farming, the design and construction of offshore installations, industrial software, and environmental technology.
A proposed £581 million development of a hybrid recirculation or flow-through fish farm in the uninhabited hillside terrain of Mealista on Lewis could create up to 200 jobs and produce up
to 90,000 tonnes of Atlantic salmon. The plans are based on the company’s ongoing development of an underground fish farm on the Norwegian island of Utsira.
No matter how clever a piece of equipment or technology may be, the reality is that it will be at risk of failure if the intended users are not able to make it work. To ensure innovation delivers the desired results, technology must be perceived as a new, valuable and hard-working ‘colleague’. Collaboration and consultation with the sector is a critical part of the adoption curve.
We have seen first-hand that definitions, terminology and even the naming conventions can be vastly different between different organisations operating in similar areas, whether of farm site locations or identification of disease threats. But where technology is designed to benefit the whole sector with greater knowledge and data, the language and procedures must be standardised.
Through our work with Lantra, the sector skills council for aquaculture, and the Scottish Association for Marine Sciences (SAMS) – funded by the Department for Environment, Food & Rural Affairs (Defra) – SAIC has developed training on standard operating procedures for detecting and reporting HABs in open coastal waters. Initiatives like this could be replicated across other areas of aquaculture to boost the effectiveness of technology-derived predictive models and early-warning systems.
Any new technology risks falling into what is known as the ‘valley of death’ if there is not sustained support to bring that technology to adoption. Whilst setbacks can add to our sum total of human knowledge, there is a need to use every failure as an opportunity to take the information learned and apply it to something new.
All successful R&D adoption requires a combination of patience, persistence and practice that cannot be overlooked, especially when live animals are involved. There are many exciting opportunities to use technology to improve the sustainable production of finfish, complementing or enhancing our understanding of fish biology and the natural marine ecosystem. But ultimately, we need to understand the biology first if we are to improve fish health and welfare.

In the contemporary aquaculture industry, the imperative to develop sustainable filtration solutions becomes not just a matter of convenience but a moral and ecological necessity. Traditional filtration methods are not only resource-intensive but also contribute to environmental degradation through extraction and production processes. Moreover, the disposal of used filtration media further exacerbates the burden, perpetuating a cycle of waste and environmental harm.
AFM® Activated Filter Media by Dryden Aqua stands at the forefront of this movement, pioneering a transformative approach to water filtration that transcends mere efficiency to embody the principles of upcycling and environmental stewardship.
There are two types of AFM. AFMs (standard) and AFMng (new generation). Unlike traditional sand filters, which rely on finite natural resources and often exhibit limited performance, AFM® offers a holistic approach to filtration that maximizes efficiency while minimizing environmental impact. A good filter sand filters down to 20 micron. AFMng of the same grain
size (0.8-1.4mm) filters down to one micron. With flocculation/ coagulation, filtration to 0.1 micron can be reached and this is fine enough to mechanically remove 95% bacteria from water. Through a meticulous engineering process, recycled glass is transformed into a high-performance filtration medium, capable of surpassing the filtration capabilities of conventional sand by orders of magnitude.
The Science Behind AFM®: Engineering Excellence
At the heart of AFM®’s efficacy lies a sophisticated activation process that imbues recycled brown and green glass with enhanced adsorption properties and an enlarged surface area. This process not only amplifies filtration efficiency but also imbues AFM® with unique bio-resistant properties, mitigating the formation of biofilm and prolonging filter lifespan. Through a three-step activation process, AFM® attains a larger surface area and enhanced adsorption capabilities, resulting in unparalleled filtration efficiency.
Moreover, AFM®’s ability to filter particles down to microscopic levels, including bacteria and organic contaminants. This fine-tuned precision surpasses traditional sand filters, enabling the mechanical removal of bacteria from water—a crucial aspect in various industries, including drinking water production and aquaculture. By combining cutting-edge technology with environmental conscientiousness, AFM® sets a new standard for sustainable filtration in the 21st century. Biofouling and channeling pose significant challenges in
conventional filtration systems, leading to decreased efficiency and potential health hazards. AFM®’s bio-resistant surface, catalysed by iron and chromium oxide, creates an inhospitable environment for bacterial attachment, mitigating the formation of biofilm and clumping. This resistance to fouling ensures consistent filtration performance and prolonged filter lifespan.
AFMs is negatively charged. This makes it ideal for removing positively charged particles such as metal oxides.AFM® finds applications across a spectrum of industries, including animal systems, swimming pools, industrial processes, and wastewater treatment.
Jakob Surber, Technical Expert at Dryden Aqua explains, “The brown and green glass used for the production of AFM gets its colour from Iron-(brown) and chromium oxide (green). These metals act as a catalyst on the enlarged surface of AFM, catalyzing tiny amounts of water and oxygen into free radicals. (This happens inside every beer and wine bottle, albeit at a much smaller scale, as there is only a fraction of the surface available for the reaction.) This creates an unsuitable environment for bacteria to attach. As long as bacteria do not attach to a surface, they do not form biofilm. Biofilm in sand filters leads to clumping. These clumps block the filter, decreasing the effective filtration surface area. When a part of the filter bed is blocked channeling occurs. Through these channels, the water rushes at high speeds, without being filtered. “
“In the worst case scenario, the inside of clumps can become anoxic, leading to the production of hydrogen sulfide, or act as a breeding ground for pathogenic bacteria.”
The production of AFM® exemplifies a commitment to

environmental responsibility at every stage of the manufacturing process. Utilizing locally sourced recycled glass and renewable energy sources such as battery backed solar power, AFM® minimizes its ecological footprint while maximizing resource efficiency.
Furthermore, water conservation measures, including rainwater harvesting and filtration (as water could be recirculated), ensure that every drop used in the production process is utilized to its fullest potential. By reimagining waste as a valuable resource and embracing sustainable practices, AFM® embodies the ethos of circular economy and sets a precedent for responsible manufacturing in the filtration industry.
In aquaculture, Advanced Filtration Media (AFM) finds versatile application across four key areas, delivering numerous benefits. Firstly, in intake filtration for both open water and borehole intake, AFM offers finer filtration than sand, with lower energy usage and easier backwashing compared to ultrafiltration. When aerating the water as pre-treatment, AFMs can be used to remove the oxidized heavy metals. In a side loop AFM can be used to crop out organics, that are too fine to be removed by the drum filter. Lower TSS reduces physical stress, BOD, and bacterial proliferation, leading to improved survival and growth rates. In systems with lower water volumes, but more delicate animals (such as parent systems or hatcheries) full media filtration is viable. Combined with flocculation/coagulation AFMng filters down to 0.1 micron, enabling mechanical pathogen
removal. Finally, AFM enables outlet filtration to meet stringent waste water regulations, with the potential for water reuse, ultimately promoting sustainability and efficiency in aquaculture operations
As the world grapples with the challenges of climate change, resource scarcity, and environmental degradation, the importance of sustainable filtration solutions cannot be overstated. AFM is produced 100 percent from local, recycled glass. Sorted out white glass is sent back to bottle production. The fine particles caused by production processed into glass wool or foam glass for insulation and construction. The washing plant runs on rain water, collected from the roof the adjacent warehouses. To reuse the washing water as often as possible, it is filtered through AFM filters. The Factory runs on 100 percent solar energy produced by the over 7000m2 of solar panels installed on the roof, buffered by a total o 1500kwh battery capacity. The only part where we have not yet managed to phase out fossil resources yet, is the natural gas needed for the thermal activation process.
In conclusion, AFM® Activated Filter Media represents not just a technological innovation but a paradigm shift towards sustainable filtration practices. By upcycling post-consumer glass, enhancing filtration efficiency, and minimising environmental impact, AFM® sets a new standard for responsible water management.

Most RAS farms must depurate their fish of the off-flavour compounds geosmin and 2-MIB to get them ready for harvest.
eAOP® combines UV light and a proprietary nanotube photocatalyst, producing hydroxyl radicals to rapidly break down geosmin and 2-MIB in depuration systems, instead of flushing them down the drain. This results in significantly lower off- flavour contaminant concentration in the depuration system, speeding the depuration process, reducing biomass loss and decreasing water consumption.
Besides reducing operational costs, shortening depuration cycles decreases the capital expense of building sufficient depuration capacity, lowers the footprint of the depuration facility, and decreases the water demand of RAS facilities.
eAOP® has been proven to decrease the depuration time by 50 percent and water consumption by 80 percent or more. This enables RAS operators to open facilities in areas facing water scarcity, simplify permitting for new operations, and improve public relations with local communities, faster and at a lower cost.
This new product contributes the company’s mission and complements their existing portfolio: Drumfilters: 5 models, max capacity up to 140m³/h. A high effectively used mesh area results in low water consumption and small footprint. Suitable for fresh and seawater.
Non-metal Pumps: MDM Inc.® non-metal pumps are characterized by simplicity of design, very high energy efficiency, long service life, low total cost of ownership and low life cycle cost.

A-Biomass® - Real-time accurate biomass reporting
Ace Aquatec has spent five years developing a state-of-the-art camera system utilising the power of AI (Artificial Intelligence) to accurately measure fish dimensions without human intervention. The A-Biomass® is an underwater camera that helps farms effectively monitor fish welfare, prevent mortalities, and provide transparency and traceability over the fish lifecycle and supply chain. It has been built using the latest AI and camera technology and can be used for a range of fish species. Using the power of machine learning, A-BIOMASS® can help farmers and producers gain an accurate insight into your pens without handling or manual intervention.
Accurate sampling = accurate data
Manual sampling can be stressful for fish and resource consuming. With average manual sample rates of approximately 100 fish per month, this process provides insights based on only a small portion of the population. The A-BIOMASS®’ stereoscopic cameras capture the fish continuously throughout the day, measuring fish length and height, calculating accurate weight estimation data which feeds directly into the Ace Aquatec portal. Available online, the portal allows the farmer to see the data in real-time, without having to go near the pen. The future of fish farming is here
Accurate data is the lifeblood of any aquaculture business. It provides insights that lead decisions on feed timings, disease mitigation strategies, harvest schedules, and stocking density management. The plug-and-play system is easy to set up and starts capturing fish data from the moment it is installed. Developed for the harshest environments, the marine grade system is lightweight at 8.5kg and easy to deploy.

Low Frequency protection is the latest generation of acoustic startle response (ASR) devices, and more effective than older acoustic deterrent devices (ADDs).
Older ADDs build a temporary acoustic barrier around a pen, which predators can breach. Our award-winning ASR device instead creates a behaviour change, meaning that breaks in the acoustic signal do not lead to a window for predation.
The Flex and Ring Acoustic Startle Response devices protect farmed fish from predators without harming marine mammals. They target marine predators, such as seals and sea lions, but avoid the specialised hearing ranges of dolphins and porpoises.
A triggered mechanism produces a low-frequency sound to startle any predators. It delivers randomised frequencies and tonal patterns to prevent seals and sea lions from becoming accustomed to the sounds.
The signal requires less acoustic output into the water than older-generation barrier systems. It takes only ten milliseconds from the start of the noise to reach its peak to create a physical response in marine mammals which they cannot ignore.

The LSM-125 hose pump is suitable for pumping thick liquid media or large particles.
This hose pump is widely used in the Agro/Biogas industry, the fishing industry or the mining industry, where the pump has to move large particles. As standard, the pump is manufactured in steel, then hot-dip galvanised. The pump can also be manufactured in plain steel and then powder coated, LSM pumper also offer special coatings for extremely aggressive environments.
LSM-125 pump can also be supplied with a hydraulic motor.
Compared to our competitors, LSM pumps have an advantage, as our hose pumps have a larger pump housing, and thus the hose is longer, and we can therefore give more per revolution. This means that we can make the same volume as our competitors, but at a lower speed, which then means a longer service life for both gear and hose. The special role adjustment provides optimal compression of the hose, lower friction, better lubrication and less power consumption than other pumps - especially compared to hose pumps with drag shoes.
LSM offers four different types of hose as standard, Nature, EPDM, Nitrile, and food-approved hose.

A New Zealand-first – and a world-first in farming the King Salmon species in the open ocean
Carl Carrington, NZKS Chief Executive Officer describes the process to gain resource consent, Fisheries New Zealand approval and to find common ground with iwi, eNGOs and the community as being “very robust.”
Carl describes the next steps, having achieved this milestone, as “needing to walk before we can run.”
“From here, we will complete our 18-month programme of rigorous benthic (seabed), seabird and marine mammal monitoring. This will provide a baseline of information, against which we can measure the impacts of a working salmon farm.
“The next step will be a ‘proof-of-concept’ phase, putting in the trial pens from June 2025. This is when it starts to get exciting from a farming point of view – building a smallerscale pilot farm so that we can trial new infrastructure while monitoring the welfare of our salmon, to ensure they can thrive,” Carl says.
Blue Endeavour, when fully operational, could generate NZD$300 million in new revenue per annum. Regional economies will benefit from growth in supporting infrastructure and services required, such as boar servicing, and skilled jobs in farming, engineering, processing and more.
Carl describes New Zealanders’ support for this kind of aquaculture as being “incredibly important” to NZKS. “New Zealanders love their Kaimoana, but not everyone is able to catch it for themselves and for their families. Salmon is a highly nutritious source of healthy protein and consumers are also starting to appreciate that farmed salmon has a low carbon footprint compared to many other animal protein sources.
Nine years ago, New Zealand King Salmon (NZKS) started the resource consent and consultation process for its Blue Endeavour open ocean salmon farm. Today they celebrate achieving final Government approval to proceed with an aquaculture project that will be a New Zealand-first – and a world-first in farming the King Salmon species in the open ocean.
“We have never taken the support we have for our products and what we are doing for New Zealand aquaculture for granted. This drives us to continuously improve our environmental footprint across the company, and was a motivator during the past nine years of dialogue and consultation to get the green light for Blue Endeavour.
“While we have some way to go until Blue Endeavour is fully operational, today is a day for our company to celebrate the successful completion of this chapter,” Carl says.
Grant Lovell, NZKS General Manager of Aquaculture, describes the open ocean as “an exciting opportunity and the next logical step for New Zealand’s aquaculture industry.”
“When we look to the open ocean we are looking at the future for salmon farming in New Zealand – in cooler, deeper waters. It is a bit of a new frontier for our aquaculture industry – but one that we are entering one step at a time, backed by science and evidence-based decision making,” Grant says.
During an extensive planning phase, NZKS undertook comprehensive assessments of the environmental effects and applied independent science from the Cawthron Institute, SLR Consulting and Roberson Environmental.
“Putting fish pens out in the open ocean is not for the faint hearted. We will be working in a dynamic environment, with waves up to 10 metres high – anyone that has caught the Cook Strait ferry knows what we are talking about.
“We will be trialling technologies and investing in mooring grid infrastructure to ensure we are able to adapt to the Cook Strait conditions” Grant says.
In aquaculture, fish and shrimp are constantly exposed to pathogen pressures, environmental fluctuations and other production stressors, negatively impacting survival and productivity.
At dsm-firmenich, we offer solutions to protect aquatic animals, reducing the risk of health and welfare challenges throughout the production cycle.

“Please drop by our stand and ask for more information – about anti-fouling coatable DHPE netting, a refined net interface system, Lift-Up and recycling routes for netting materials.”
For the first time, Aquaculture UK will host an ‘innovation theatre’, designed to showcase the fast-changing technology driving the sector. In a tent just outside the main exhibition hall, the theatre will feature 30-minute presentations, which are open to anyone with an innovative idea or invention to promote.
Companies lined up so far include RS Aqua; the University of Stirling; Global Underwater Hub; Vonin; Benchmark; Umitron; UKRI – Biotechnology and Biological Sciences Research Council; Seneye and Moredun Scientific.
There will also be breakfast briefings across the two days, from 8:30-9:30am, and a full conference programme, to be announced soon.
Cheri Arvonio, Event Director at show organiser Diversified Communications, said Aquaculture UK offered unrivalled access to the people and products shaping the future of aquaculture. “We have increased the size of the show this year, with 30 additional exhibitors, to reflect the growth of the sector as new technology and services enter the space.
“As the countdown to May begins, excitement is building already for what promises to be a truly bumper show.
“We can’t wait to open the doors to Aquaculture UK 2024 and welcome the aquaculture community to our biggest exhibition yet.”
The latest and eighteenth edition of North Atlantic Seafood Forum (NASF) took place from 5-7 March, with a record turnout for the second year in a row. 964 delegates representing 400 companies and coming from over 30 different countries attended the event, including our very own Costa Skotidas, Content Development Manager, who was in attendance for all three days of the event and got the chance to meet with some of the speakers and attendees.
When discussing the record-breaking event, André Akse, General Manager of NASF stated “We are grateful and humble to the fact that so many executives and industry leaders prioritise to join NASF in Bergen these days. And in this way, we contribute to secure the North Atlantic Seafood Forum’s position as the world’s largest seafood business conference, and probably the best networking event in Seafood!”
Talking to Costa Skotidas about NASF 2024, Nina Stangeland from Grieg Seafood said, “It’s a great event. You get the latest information like reports, market data analysis from the seafood industry by attending the event. And it’s great to see new innovation also. And I think it’s the perfect place to meet the right
people that you need to talk to within the industry.”
This idea of NASF being one of the go-to events for networking and marketing within the Aquaculture industry appeared to be a consistent theme across many of the attendees, with Kjartan Maestad from Cargill stating “It’s a really important meeting place for business people because it has a standing that makes people from all over the world come and attend. So it’s a really good place to meet a lot of different people in addition to all the interesting presentation that’s being given.”
One key feature of NASF 2024 was the Seafood Innovation Award. This award gives chosen start-ups the opportunity to showcase innovative business ideas to potential customers, partners, and investors as well as receiving NOK 100,000 if they win. The winner of the award this year was Blue Lice, a Norway based company founded in 2017. Blue Lice use their system to attract and capture sea lice before they can reach salmon by using nothing but light, an idea that could prove to be greatly beneficial as salmon lice is one of the biggest threats to fish welfare in

the industry today. We got the chance to talk to Karoline Sjødal Olsen from Blue Lice commented when asked what they would do with the winnings “I’m also looking at this as the money that we can use for marketing because we just upgraded our business - our logo and our branding and this could be some extra money we can use on doing more on that. We’re more heading towards the growth and the markets.”
Technology is becoming a more important part of our industry each day, this is one of the many reasons we started the Fish Farming Technology section of our magazine, and NASF has discovered this too and decided to dedicate an entire day to
technology with Technology Tuesday. Technology Tuesday took place on the first day of the conference and was dedicated to advancements and new technology initiatives, which included not only companies showing off their latest and greatest technological advancements but also 70 presentations on advancements or technological solutions. One such presentation was by Sarah Carroll from MariHealth who described her speech during Technology Tuesday as “the industry is quite reactive to most of the solutions that they have at the moment. So our idea really is to shift that paradigm and be part of the change and be more proactive in our approach.”
Vidar Uglane, CCO and Co-Founder of Solution Seeker also had a speech at the event, and when talking to Costa afterward he said that one of the biggest challenges facing the fish farming sector was “they’re a bit tired of hearing about how much you should store data and how much you should share it and how much you should actually use it. So I think they want to see the actual solutions.
“I think you need to show value through actual applications and better decisions instead of just talking about it”
The CEO of Stolt farms gave a presentation about their company – focusing on their expertise and uniqueness within the industry. The talk given by Brett Glencross, Chairman of IFFO, also gathered attention at the event. He spoke about the importance of being objective when we look at sustainability. “What we are trying to do at IFFO is to coordinate a global a life cycle assessment for the entire marine ingredients industry from the producers”, Brett commented.
Gaëtan Fabritius, Chief Business Officer for Bioceanor gave a presentation on water quality forecast and how water quality impact production and fish welfare.
We also had a chance to meet Alex Diana, Product Manager at Innovafeed, whospoke at the event as well. “In our presentation, we prioritized key insights from Innovafeed’s Impact Report to underscore our commitment to sustainability and corporate responsibility. We’re emphasizing how our “Tech for Impact” model addresses pressing global challenges such as Climate Change, Biodiversity loss, Food Security, and Local Socio-Economic Impact. We’re highlighting specific strategies outlined in the report, including reducing carbon emissions by 80 percent, preserving forage fish, meeting increased protein demand sustainably, and creating local job opportunities.”
NASF will return next year, in Bergen on March 4-6, the hosts have already begun planning the event and are no doubt looking to break records for a third time. We will no doubt be in attendance to help them with their mission and look forward to seeing you all there!
Sven Kolsto and Morits Halkjelsvik of OptoScale with Costa Skotidas. The company exhibited their key product Bioscope. The bioscope is a measuring instrument that photographs passing fish in the pen, providing you with information about the facility’s condition. With the bioscope, you can weigh tens of thousands of fish daily, examine their health, and gain a complete overview of lice counts. The Bioscope analyzes the images and sends precise data directly to you.
Patricia Sugui, Sustainability Manager, CJ Selecta. Patricia spoke at NASF about innovations and tools to prevent deforestation in Brazilian soy crops. CJ Slecta’s core business is to sell soy protein concentrate for Salmon in Norway and Chile. “We believe that we need to be more committed towards sustainability. We know brazil has been misjudged as a country without strong environmental policies and I came to NASF to explain that we have many actors of sustainable farming in Brazil ”, says Patricia .

Antonios has over 14 years’ commercial and R&D aquaculture experience on marine hatchery production and feed innovation in the UK and internationally. Antonios has a PhD in Fish Health and Nutrition and MSc in Sustainable Aquaculture from the University of Stirling (Scotland) and a “Ptychio” in Ichthyology from the University of Thessaly (Greece). In addition, he is on the board of directors of the European Aquaculture Society (EAS) and a member of the Geotechnical Chamber of Greece (GEOTEE).
you have a rich career in the industry what initially lead you to this field?
Pure luck. All I remember is that I always had a passion for the sea and aquatic life – and coming from Greece, a country with a long coastline, it certainly helped!
Later on, I realise how diverse the aquaculture industry is and did not know where to focus, so I just started trying different things in various countries. The first step was with my studies in Ichthyology at the University of Thessaly and project work in Greece, where I got a broad exposure and a strong stimulus for aquaculture. Following on, the MSc in Sustainable Aquaculture at the University of Stirling exposed me to the global scene and challenges of the sector. Wanting to understand more about applied research and rise to the challenge of scaling up the production of a new species (i.e. ballan wrasse), I found myself working in marine hatcheries (Ardtoe and Otter Ferry Seafish) while doing a PhD at the “tropical” west coast of Scotland. My next step came from the opportunity to work with BioMar exposing me to more international commercial, technical and product management side of feed. Most recently, I joined Devenish to develop the aquaculture side of this agri-technology company with long history and strong global presence in agriculture. Plenty to learn and even more to do!
One thing led to another really but looking back the common thread of the past over 14 years was linking R&D with production and develop solutions to scale up production. The catalyst in my career is the people I have met and work with. I feel privileged and extremely lucky to have met such incredible professionals who have helped me throughout this journey.
As someone deeply involved in the European Aquaculture Society, what do you find most rewarding about contributing to a sustainable future in aquaculture?
Knowledge exchange and collaboration are key for the development in any industry. The European Aquaculture Society (EAS) plays an instrumental role bringing different stakeholders together to promote and develop the European aquaculture.
Having been an EAS member for over 12 years now, I had the opportunity to be the president of the student group and currently I am member at the EAS Board of Directors. These have given me the chance to encourage industry engagement with the academia, increase market awareness of the EU sector and strengthen employability and skills of early career professionals.
Being able to contribute to this evolution of the aquaculture sector through EAS, I feel honoured – and this is the biggest reward for me. And of course, meeting new and old friends is always a bonus!
Addressing continuously increasing raw material prices, could you discuss your personal insights into the factors that influence this and how you, as a professional, work to mitigate these challenges in fish feeds?
The pressure to cover the global demand for high quality protein is higher than ever, leading to continuously increasing pressure on the intensity of aquaculture and feeds. Increasing raw material prices is a result of production intensification and scarcity of resources.
I believe that increasing efficiencies across the supply chain would mitigate the challenge of soaring prices. Given that feed is right at the middle of the supply chain and responsible for most of the operational costs, a big part of the accountability falls to the “feed people”.
My personal career path is focused on developing commercially driven solutions towards improving productivity and efficiencies. This is either through policy (with EAS) or directly with my work on feed additives with Devenish. The terrestrial animal farming sector has a much longer history than aquaculture and we have a lot to learn from it. There is no need to reinvent the wheel.
My current work is focusing on optimization of feed production, efficient nutrient utilisation and growing healthy animals. This involves anything from developing processing aids and formulation savings for the feed factories to health promoting strategies and adding value through the supply chain.
Developing together with adopting established solutions in feed additives and farming practices, I have seen extensive improvements towards more economic and sustainable systems. It seems that we are on the right path to a cost effective and efficient future.
How do you see consumer preferences and demands shaping the development of aquaculture products and practices in the coming years?
The need for good quality aquaculture products can be translated in different ways such as sustainable, cheap, or easy to produce –depending on where in the world you are. Ideally, all these can be combined, but practically this is impossible, and the market defines the local priorities.
The issue is that, often, consumer preferences are led by misinformation, which is unfair for both the buyer and the producer. Big steps have been taken towards a more sustainable future and these need to be communicated to the wider public with a stronger voice. Subsequently, consumer awareness will play a big role to the products and practices of the future.
The aquaculture sector has a moral duty to produce truly sustainable products and not turn sustainability into a box ticking exercise of a
short-sighted “market demand”. We need to develop solutions without adding more environmental pressure to the system – as this will defeat the purpose of sustainable growth.
What role do you believe aquaculture can play in addressing global food security and nutritional needs, particularly in the face of population growth and environmental challenges?
Current food systems often fail to deliver nutritious and affordable food to many people around the world. While there is no more space to develop further the terrestrial food production, aquaculture is barely scratching the surface of its “territory”. Farming, in general, is part of the solution and not the problem – when it is done right. Working closely WITH regulators and research institutions through collaborative research the sector can maximise the utilisation of available resources, while keeping the environmental impact to a minimum.
Aquaculture has the highest potential for food production globally – there is no question about it. However, given that it is a relatively new industry there is still a lot to be learned and improved.
Despite the great diversity of over 500 farmed aquatic species globally, the focus is still on just a few in each region. This lack of farming diversification and geo-clustering increases the risk of health crises, market fluctuations, and limits the flexibility towards environmental changes. Polycultures can offer biological control of health issues, improve water quality, and provide a secondary crop to the farmers, together with the possibility to farm species suitable to seasonal environmental conditions. It seems that the climate is changing faster that we can adopt the farming conditions to it.
Development has and will exhibit different fluctuating patters in growth among regions and species. This is primarily driven by local resources and market requirements. I strongly believe that the markets need to be more focused towards consuming locally produce species with low environmental impact on production and transport. I am not convinced that delivering an “exotic” species to the other side of the world, simply because of a “market demand”, would ever be sustainable. As a sector, we need to be better at communicating our message to the consumers, and work towards finding solutions – not create unnecessary problems.
Aquaculture certainly can be part of addressing global food security, by building an environmentally, economically, and socially sustainable future for everyone. This can only be achieved with an ethical, anthropocentric, and truly sustainable approach.
