Summary Pilot trials of Fishface, videoing day boat catches, and then using the videos to identify species, numbers, and estimates of size using a Garmin VIRB elite (with GPS) were highly successful. Although it has not yet been possible to do the range of gear types envisaged, it is clear that all the technical capabilities required are their for observer based video capture of a day’s fishing activity and subsequent analysis of very high definition video. Some of this video has already been used to support a separate Cefas Fisheries Science Partnership project; This work-in-progress report: documents three trial runs using the Garmin VIRB elite; provides the links to the videos on YouTube; provides an annex with a fish-by-fish guide to the contents and timings of these; does the same for three further videos shot using a Sony TG7VW video camera; provides some illustrative examples of the potential data that can be extracted; gives some suggestions as to how this might be developed, and potential strengths and weaknesses; identifies potential partners who should now be approached; encourages potential partners to examine the videos and contact modus vivendi if they have an interest in potential collaboration; and suggests now proceeding to arrange a workshop while meanwhile attempting to also gather video on under-ten metre longlining and potting. With thanks to the Lighthouse Foundation, Hamburg, for funding this pilot.

Initial findings Video capture on vessels by observer Trials with the Garmin VIRB elite on board FH214 Lady Hamilton were very successful. On-board performance The 16GB data card and two batteries were sufficient to capture over 3 hours of high resolution video and last a day’s hauling activity, despite continuous filming (which can reduce battery life – as battery performance deteriorates at lower temperatures three or more batteries might be required in winter). With a slightly elevated position (top of cabin door) it was possible to capture continuous video without either getting in the way of the crew, or the crew obscuring the view. The ultra-wide angle view was judged the most effective: When within 1-2m of the hauler it was of more than sufficient resolution to identify fish on the hauler, while having a view over as much of the boat as required. However, even within the waterproof housing, wind noise was an issue in an exposed position at the edge of the vessel – and sound can be useful: for example the sound of a scallop dropping into the hauler tray allows one to distinguish between live animals and shells.
Garmin VIRB elite (right) plus waterproof housing, articulation arm and adhesive flat mounting pad plus a one euro coin for scale. The camera is inserted into the housing through the hinged front facing away from the camera. Note the video on-off slide on the top of the housing. The fixed joint articulation was not as easy to orientate as a ball and socket mount but was manageable.
Image Quality The VIRB elite captured video of exceptional quality (with freeze frames approaching the quality of still photography) allowing the immediate 4

identification of virtually all fish – it was more reliable that identification onboard the vessel. Links to examples are included in this report. The associated Garmin software provided the necessary tools for editing video and overlaying a range of basic but useful GPS derived graphics and data onto the final output. Overlays (numbers or graphical) can be positioned and sized by the user and templates created. Those overlaid on the Fishface video were: date, time of day, time into video, the track of the boat and the position of the boat on that track. Less essential, but included, was the compass bearing and speed of the boat. The software displays a map, from which the total length of the trail can be taken (although there is no marine chart data). Fishers might be cautious about giving away fishing marks, especially with relative performance is shown, but the data ultimately be used to produce maps of fish density to a lower resolution, and other indirect uses (and of course personal use or shared between fishers under their control). Well established approaches have been developed to dealing with confidentiality with other biological mapping schemes. Species, size and event time (i.e when each fish came over the hauler) were then extracted into spreadsheets, and summary graphics and accounts produced. Stuttering and jumps in video was an issue when reviewing video within the VIRB software that slowed species counts. This might have been an issue with the software, or with the ca 4 year old laptop. Once exported as a movie file, this issue disappeared when viewing with Quicktime although there was a marginal reduction in video quality. Quicktime also allows scrubbing (shifting back and forward through video frames at user-controlled speed via trackpad or mouse) that was very convenient. In addition to the video file, the VIRB elite also produces a standard .gpx GPS file of the vessel track, which can be imported into GPS mapping software, including the open source Mac and PC QGIS software. This opens the route to logging fish data within mapping software as well as incorporation into statistical software such as R. Sequences of clearing the nets of up to the maximum file size produced, of 7.5 GB/48 minutes, were uploaded successfully to YouTube (see later section for results and links to video). Size estimates of fish have not yet been analysed. The estimates were made against the known dimensions of the hauler top roller, but requires judgement of perspective effects. More elaborate haulers, such as that on the Lady Hamilton with trays, have more points of reference to make estimates. Temporary (e.g. adhesive scales) could be attached to the hauler. Abrasion would be an issue to be resolved for long term video monitoring. Collaboration with a hauler manufacturer might be fruitful – Spencer Carter is based in Falmouth, adjacent to Lady Hamilton’s home port and the skipper of Lady Hamilton has already indicated interest in being a platform for more extensive work. Estimating size will be an approximation. There is an interesting debate to be had about just how precise these need to be, especially if very large amounts of data can be obtained quickly but crudely: ± 5 cm might be more than sufficient. The video is always available for re-analysis 5

Conclusion: this system could already be used, out of the box, where there is a dedicated person recording video on the vessel, and the data is then extracted manually, either by the same person or (depending on the amount of video being generated), e.g., as part of a citizen science or student project, university or other research establishments. Fishface video has already been pressed into service as input to the Cefas FSP 2014/44 haddock large gillnet project.
Video capture on vessels without an observer. The crew activity on board fishing vessels is intense when hauling and clearing gear. So it is not likely that a crew member would spend long periods of time producing hand held video of the type produced by observers. However, the VIRB has a waterproof housing designed to be mounted on structures in a multitude of ways (see earlier photograph). A mounted camera could be turned on and off by crew as required. The ideal positions for the camera, as established in the observer gathered video, are also at convenient mounting locations within arms reach and line of sight of the skipper where no observer is present. This will be important for turning the camera on and off, and clearing salt spray etc off the camera housing. Shielding might help reduce exposure and wind noise. One standard option for attaching the mounting arm of the VIRB is a flat base plastic ‘one time’ adhesive pad. Given the type of sudden shocks this is designed to withstand in sports use, one might assume this is good enough for marine use (to be tested!). Recommended curing temperatures for the adhesive suggest that this would not work in winter. An alternative would be to mount it on an intermediate surface, and that this is e.g. screwed or otherwise mounted in location. As boat equipment and cabin layout vary extensively, it is suggested that the skipper shoot a short video of hauling positions from potential mounting positions (this can be done in harbour), so that options can subsequently be discussed. Once a number of boats are providing video, it will also be possible to produce a short guidance video of dos and don’ts. This would avoid the cost of observer trips to new boats. However it is suggested that it is worth an observer going out on a range of vessels in the first instance when the learning curve is at its steepest. This will also mean that video clips of fish can be obtained for use as a reference database for species identification (e.g if identification is done as part of a citizen science or university student project). Since the Fishface proposal was produced it has been widely reported that video can be shot on Garmin VIRB elite from a power supply rather than battery (which otherwise will need to be exchanged at least once during a working day). For this reason, plus the dedicated software and GPS trails and overlays, trials of
6

modus vivendi
an alternative non-waterproof but powered in-car camera have not gone ahead1 . Wired, rather than battery, power removes one irritant for everyday use by the crew. It would required drilling a hole in the rear of the waterproof housing, and the cable seal would need to allow the cable to feed through to drop the camera out through the front of housing when exchanging memory cards. These would likely need to be swapped out every one or two days. Wind shielding might also help avoid the risk of salt-water penetration. Hard drive storage is not an option with the VIRB. However, noting Garmin produce marine plotters for fishing boats, and that the USB cable carries both power and data, there might be a fruitful collaboration potential – Garmin’s European HQ is in Southampton. There are a number of other potentially attractive features about the VIRB. It can be switched on and off from a phone App, or a small dedicated remote, as long as it is in wireless range, which it will be on day boats. Second, a VIRB can be set up to drive one or more slave cameras. That might be useful, for example if stereoscopic vision was thought to be a useful feature for automatic recognition and size estimation of fish as part of a computer(-aided) image recognition project, or if more than one viewpoint was required. The Garmin VIRB elite is currently priced (January 2015) in the UK at £175 including 20% VAT, a halving of price since mid-2014 that may indicate the introduction of a new model. Note that its main rival, the GoPro, does not incorporate GPS. The main disadvantage compared to dedicated systems (given that this is not an enforcement camera, and legal standard tamper-proof video is not required) is lack of hard drive or higher card capacity that might allow a weeks data to be collected uninterrupted. Conclusion: Hand-held video capture by crew is unlikely - there are too many other jobs to do, and short shots grabbed as and when possible are unlikely to capture important moments or satisfy third parties. Mounted cameras, ideally but not essentially with a power connection, are very practical for short term intensive monitoring to establish some point (such as level of discarding, bycatches, evidence of any seabed damage, as well as fish stats). Skippers have already come forward would be prepared to gather data (although not process it) for longer periods of time, and be involved in an experimental development programme.
The VIRB has a reported maximum card capacity limit of 16GB, as used here. In the project proposal, in car video cameras were also included as an option, with a 128GB capacity limit, which might allow a week’s video to be captured automatically whenever the boat’s electrics were turned on. These haven’t been tested yet, and may not be, because these are not waterproof and doubts that it will be possible to find in-cabin locations that have clear sight of gear hauling, these needing to be above head height (cabin door top frame height, rather than window height) 1

Next Steps The aim of the pilot was to gather video from a greater number of vessels with dierent methods. A couple of things have delayed gathering video from a greater variety of vessels. Currently suďŹƒcient is known from direct evidence gathered for netters (especially with the opportunistic analysis of earlier video coverage from another project), but it would be good to gather video from other mĂŠtiers, e.g. long liners and potters if possible. However, in terms of pilot task to establish technical feasibility, the main point of this interim report is to state that it is clear that it is technically feasible. Enough has been achieved, to go ahead with contacting potential collaborators and fix a workshop date. At another level, a series of questionnaires have been developed to establish awareness of technical capabilities, the potential usefulness, and potential pitfalls for fisheries stock assessment scientists, for fishers, their representative organisations, and for fishing managers. These are now ready to be used: this probably needs to be done actively and in a targeted fashion by means of telephone interviews of 20 minutes. Alternatively, the questions raised could be used to guide the workshop programme. So additional next steps would be: Identify representative body or bodies representing fishers in UK and/or Europe for possible collaboration/ establish mechanism for fishers having oversight of data usage and development of project. To now circulate this initial report so that potential collaborators (academic, public, commercial, and others) can evaluate the video, vis those: who may be able to assist with counting fish (University teaching or research departments, citizen science projects (Zooniverse for example), European Environment Agency, ICES, national museums (where these are record keepers), commercial fishing organisations, sea angling organisations, possibly food and/or environmental NGOs). working with fish statistical analysis (eg open-source R) and GPS software (eg open-source QGIS) to assemble a convenient set of graphical and statistical outputs and standardised inputs; dealing with fisheries research into distribution and abundance of stocks; dealing with computer image analysis (video hardware and analytical software); dealing with data output, including App development for end users; equipment manufacturers with an interest - hauler manufacturers (e.g Spencer Carter and others) and GPS/Chart Plotters/Fishing data logging (e.g Garmin and others)

other developers, e.g visual identification tags on fishing gear (for example so that performance deterioration of gear with age can be calibrated, length markers incorporated into gear that can easily be recognised in video etc) To now circulate this initial report and discuss potential for collaboration with fisheries management and related bodies: local: !
e.g. in England and Wales IFCAs (ideally local bodies in other countries, within resource constraints?) national:
!
e.g. in UK MMO, SeaFish, Environment Agency, SEPA, Natural England, SNH (ideally in other countries, but resource constraints?) Europe: European Commission (DG Marine, DG Research), European Environment Agency, the Regional Advisory Councils. International: eg Africa as a region, also international bodies like FAO, UNEP, as well as international conservation organisations such as IUNC (e.g. mapping).
To consolidate potential funding streams and partnerships for future steps: The recommended outcome from modus vivendi’s perspective would be to have funding to pursue the pulling together a collaborative effort involving fishers, researchers, analysts, enablers (citizen science projects?) and app developers. This assumes that the two prime outputs are 1) better understanding of fish distributions and abundance in inshore waters and 2) better means for fishers to analyse their catch data. This is something to be discussed at the workshop. To consider the scale and nature of the next step - for example to accumulate video from X (10?) vessels in different métiers in different locations and/or to have a X vessels accumulating data in one location. modus vivendi’s interest would be from doing as many tasks as possible while the project was small (if this makes the project cost effective), to shift rapidly to a role in co-ordinating/ management as other joined the collaboration, and to then see Fishface becoming an independent entity if there was value in continuation, or for the work to be concluded and disseminated if this was the best way of getting the greatest uptake.

Initial Results & links to videos Garmin VIRB elite - Lady Hamilton: sole trammel net haul 1 The fishing vessel is FH214 Lady Hamilton, skipper Chris Bean, fishing from the Helford, in Falmouth Bay. ICES area VIIe. It uses a Spencer Carter net hauler NHO-03, which incorporates a tray to guide the fish aft and temporarily hold the fish, if required, o the deck. This is the first of two sole trammel tiers (a set or fleet, here of 8 x100m nets) to be hauled this day, along with a large mesh gill net tier. The soak time was 3 hours. Date of haul: 9th July 2014.

changing position. The annex indicates when the angle of view (from ultra wide to standard) was changed. It was concluded early in the trial that ultra-wide angle was the most suitable. The net is already passing through the hauler when the video starts. The VIRB logged a surface track of 300m, although the majority of the 800m of the net was recovered. Video Link on YouTube See Annex for event index listed by time into video. There were a significant number of fish and shellfish. It took 5-6 hours to extract data into the individually written list in the annex. Encountered issues with stuttering/ frieze /jumping video due either to the limitations of a 4 year old laptop and perhaps with VIRB elite software. It was discovered that once exported into a Quicktime video it was possible to scrub the video (freeze, move slowly or fast, backwards or forwards using trackpad) very smoothly, although there was a slight loss of resolution in the export from the original VIRB files. The stutter issue perhaps cost 2 hours of the 6. Manually typing time, species and size was slow: while ok for a pilot, the development of a simple logging system could have saved ca 1-2 hours. With regard to time taken, one needs to bear in mind that the logger is viewing video, including periods where nothing is happening, not still images. The Quicktime movie allows the logger to skim video. Recognition of a moving high resolution video was likely better than identifying from individual freeze frame still images, and many individual frames would not be ideal, even where a species was readily identifiable in the sequence from which it was taken. Identification of species from the video took very little time for an experienced observer. Catch Record 107 brown crab, 35 spider crab, 47 plaice, 8 sole, 2 turbot.

from a professional scientific perspective, or as part as a user-friendly interface in an App designed for fishers. So these are by way of demonstration. The left hand side is a straight-forward (other than use of a log scale) ranking of total number of individuals by species. This could be expressed per 100m of net (actually one net length). Visual tags in each net could allow one to factor out net deterioration with age. Electronic chips in the nets, plus sensors at the casting point and on the hauler would allow routine background gathering of precise soak times etc. The right hand side shows the size distribution of within and between individual species, ranked within each species from the smallest to the largest brown crab was the most abundant, so stretches the full width of total 107 observations. Plaice was second most abundant with 47 observations, so stretches nearly half way over the graph, etc. There are only 8 sole, but they are clearly big. In a more sophisticated analysis one would be showing the distribution of sizes around the average for each species. These estimates are as a percentage of the top roller width (which is known but has been deliberately omitted here so as not to encourage a suggestion of precision that may be unwarranted). If you attempt this, you can see that there is some judgement going on, due to perspective effects, obscuration etc. But you can also see that there is much scope for additional reference points. Also it is worth asking just how accurate does one need to be? One would certainly hope to be ±10 cm. If one was ±5 cm that might be sufficient to distinguish year classes of most fin fish. In theory it might be possible to weigh the fish on the hauler tray. However weighing technologies for use at sea (wave motion!) are not cheap.
Garmin VIRB elite - Lady Hamilton: sole trammel net haul 2 The fishing vessel is FH214 Lady Hamilton. This is the second of two sole trammel tiers to be hauled this day of 8 x 100m net (to be checked agains video). The soak time was again ca. 3 hours. Date of haul: 9th July 2014. The video starts at 12.51pm and ends at 13.44 pm = 53 minutes. The video running time is 48.16 minutes, the breaks due to experimenting with wide angle/zoom settings and changing position. In addition, high resolution slow motion and standard resolution very slow motion options were also recorded (from 3:08). The video starts before the first net is hauled. The VIRB logged a total surface track of 500m, although the entire length of the net is covered. Video Link on YouTube See Annex for event index listed by time into video. There were a significant number of fish and shellfish. It took ca 4 hours to extract data into the individually written list in the annex.

Top: Alternative viewing position, Ultra-wide angle. If the full size freeze-frame jpg is inspected it can be seen that the plaice and net surrounding it are not sharp, although the shadow cast by the net is sharp - this indicates that the blur is because camera position is too close, rather than due to motion blur. Bottom: This image, a crop from a freeze-frame at 34m 37sec, resolved one of the few examples where the hauler was too fast to identify the species directly from the video. If the distinction between brill (no spotting on tail fin) and turbot (spotting on tail fin) is correct, then this and adjacent freeze frames identifies the fish on the right as a turbot. The fish on the left is a male phase cuckoo wrasse. The camera, as the full frame image shows, is close to the position shown in the first tier haul photo, which appears to be close to the ideal position, with ultra-wide angle setting.
Catch Record Brown crab 78 in total /or 9.7 per 100m of net; spider crab 24/3, plaice 20/2.5; sole 7/0.8. Also brill, turbot, scad, thornback, lesser spotted dogfish, starry smooth hound, whiting, ling, cod, red/tub gurnard, cuckoo wrasse, ballan wrasse, scallop, lobster.

Count of species top left retained (apart from one undersized sole) and top right other species discarded from the second tier of sole trammel nets. The bottom graph shows number of fish and shellfish recovered per minute from the start of hauling (at the bottom of graph) and up to the 48th minute at the top.
The graph of individual fish retained is as in the first tier. Also shown is a graph of common starfish and a few individuals of other species discarded. The bottom graph shows distribution and abundance of species along the net. There are a large number of species, and so colours, but they always appear in the same order as the key, with brown crab always appearing far left if present and the wrasses far right if they are present. As the GPS co-ordinates are known, over time this would build up into a valuable mapping database, even more so if the records of multiple vessels and gears are collated.
Garmin VIRB elite - Lady Hamilton: 115mm gill net net haul The third VIRB trial on fishing vessel FH214 Lady Hamilton, fishing in Falmouth Bay, ICES Area VIIe, is of large mesh gill nets. Unlike the others, this is composed of short clips from three separate tiers of nets hauled in succession, spread over a total distance of ca. 2.5 miles. The video starts at 9.47 am and ends at 11.11 am = 84 minutes. The video running time is 15:04 minutes. The VIRB logged a total surface track of 500m, although the entire length of the net is covered. Date of haul: 9th July 2014. 14

The haddock outburst of 2012-13 had passed through, and the recruitment of young haddock in 2013 were either not in the area or too small to be caught in these nets. Other gadoids (whiting, cod) were also scarce in this season and year. It took ca 2 hours to extract data into the individually written list in the annex.

But the VIRB software has no marine chart data, far less the types of additional information such as permanent characteristics such as seabed type, and temporary features at the time the fish were caught, such as water boundaries and temperatures, nutrient concentrations and phytoplankton production.

Garmin VIRB elite - Lady Hamilton: other nets and other camera locations In addition to the activity also reported, both large mesh monk tangle nets and smaller mesh red mullet gill nets were videoed, exploring a higher position above the cabin (for a possible mast mounting). A screenshot, within the editing software is shown shown below. The position would not be recommended. Primarily this is because either the observer, or especially the crew in routine operation, would not have the camera at arms reach, and be able to readily check that the housing window did not need to be cleared of spray, or to change data cards. But also it turned out that a point closer to the hauler, within easy reach of the crew both produced a better, closer, image of the fish, but could still cover a wide field of view across the boat.

Usually no habitat detail is visible in the maps or satellite photos, but in this close to coastline position it is possible to make out that the nets are set on likely soft sediment just oďŹ&#x20AC; the rocky and seaweed habitat (note also that red mullet use soft sediment habitats as a feeding resource). It is possible to add text overlays to a position in the video, but not drop markers on the map. The VIRB elite does produced a GPS data file (as well as the video) for importing to other software.
Cefas FSP Project Cefas FSP project FSP 2014/44 is evaluating sustainability of the Cornish large mesh gill net fisheries in terms of low discards, low bycatch, evidence of benign impact on other aspects of marine environment, as well as adding economic value, and so qualifies for greater quota entitlement under Article 17 of the CFP. modus vivendi is working as project coordinator on behalf of the fishers involved in the fishery. The project is specifically about regard to haddock, but these 16

(mainly) 108-115 mm large mesh gill nets are used by inshore vessels to pursue gadoid fishing that fluctuates between different species over time. The Fishface interest is that: 1) considerable video footage had been collected since 2012 of large mesh gill nets (and other gear) in action, using what was then state of the art miniaturisation, the Sony HDR-TG7VE with GPS and wide angle supplementary lens, although GPS data had not been retained; 2) some of the vessels concerned were using a smaller hauler, without the tray under the hauler of the Lady Hamilton (which gives a good view of the fish for species identification in the video) and has less points of reference for estimating fish size; and 3) The Lady Hamilton VIRB footage shown above was all filmed in summer and in good light. Some of these large mesh gillnet fisheries were filmed in overcast low light conditions, so it would be possible to see how this would affect the ability to identify species. Note that this video was being gathered to generally document both environmental impact and the (food) quality of the handling. So, unlike the VIRB footage, which is trying to establish whether and where fixed camera positions might work for gathering data, the video footage ‘follows the action’ and pans away part of the time from the hauler to cover other events. FY239 Lucy Marianna 9 October 2012 4 ¼” 108 mm gill net The video from Lucy Marianna is useful because it operates a smaller Spencer Carter Solo NHO-01 hauler, without a tray. The lighting conditions were also different from those in the Lady Hamilton videos above, being overcast and with drizzle, which is useful.
Screenshot: Haddock being hauled in 108 mm gill nets onboard Lucy Marianna at 6m 48s into the video. The distinguishing characteristics of the fish being hauled (here the dark ‘thumbprint’ on the side of the haddock) were sufficient to allow identification despite lower resolution of the video camera compared to the VIRB and poorer lighting conditions. However there was no exportable GPS data.

Video Link on YouTube See Annex for event index listed by time into video. It can be seen from the video that the main issue compared to the NHO-03 is visual reference points for estimating the size of the fish, especially with the perspective effects as the fish was guided off the hauler, although in this case the position of the fisherman to the right who was doing much of the extraction was in line with the hauler roller. Generally it was possible to have a good enough view of the fish either coming over the hauler, or subsequently being extracted from the net, to identify the species, assisted here by the relatively limited number of species involved with this gear specification. Catch Record Nets being cleared from 0.43 to 13.00 minutes into the video Subsequent material of gutting, cleaning and icing all useful for assessing the size and condition of the fish. During the 12 minutes 4 seconds total net clearing videoed, 13 haddock, 11 pout, 5 lesser spotted dogfish and 8 scad were cleared. Other fish visible (e.g. in hand when clip starts) were 3 ling and one john dory.
There were no fish discards, no bycatch (e.g. seabirds, marine mammals etc), one small piece of seabed habitat debris (bryozoan) which could be drift. FH214 Lady Hamilton 8 October 2012 4 ½”, 115 mm haddock gill net This video was obtained from Lady Hamilton using similar (slightly larger) large mesh gill nets the day before that from the Lucy Marianna, fishing in the same general area. Video Link on YouTube See Annex for event index listed by time into video. It allows a comparison with the difference in quality between Sony and VIRB video. the Sony has greater versatility for general video making, including the zoom range, but this is not so relevant when considering fixed consistent positions with wide angle coverage for routine monitoring – where the VIRB has an ultra wide-angle setting.

quantifying fish catches — the camera position for these other tasks means that the view of the hauler is frequently temporarily obscured, and the camera pans away to cover other activities.
Catch Record Nets are being cleared of from 2:44 into the video to 24:45 Subsequent video of gutting, cleaning and icing all useful for assessing the size and condition of the fish. However in the first 22 minutes the tally of visible individual fish was 21 haddock, 2 pout, 15 lesser spotted dogfish and 6 scad. Other individual fish were cod john dory, red gurnard, whiting and spider crab. One spurdog was caught (at 15:05) and discarded (legal requirement to prevent targeting, included in video) no bycatch (e.g. seabirds, marine mammals etc). No seabed habitat debris.

Catch Record Soak time of ca. three hours. Catch in the video dominated by 46 haddock, plus 15 lesser spotted dogfish, 8 brown crab, plus scad, ling, whiting Around 21 minutes hauling time video, at 1 m per second maximum. There were also halts in hauling, so likely at most 800m -1000m of net of hauled during the video, and so ca. 4 haddock per 100 m at conservative estimate. Skipper Chris Bean heard to estimate around 100 kg of haddock from the tier – actual tier length not recorded. As typical tier is 800m this suggests that most of the haul is captured here.
