Porcupine Bank Nephrops Grounds (FU16) 2023 UWTV Survey Report and catch scenarios for 2024
This report provides the results of the eleventh underwater television on the ‘Porcupine
Bank Nephrops grounds’ ICES assessment area; Functional Unit 16. The survey was multi disciplinary in nature collecting UWTV and other ecosystem data. In total 71 UWTV stations
were successfully completed (100% of the planned stations) in a randomised 6 nautical mile
isometric grid covering the full spatial extent of the stock. The mean burrow density
observed in 2023, adjusted for edge effect, was 0.27 burrows/m². The final krigged
abundance estimate was 2002 million burrows with a CV of 3% and an estimated stock area
of 7,130 km2
. The 2023 abundance estimate was 47% higher than in 2022. Using the 2023
estimate of abundance and updated stock data imply that catches in 2024 should be
between 3677 and 4560 tonnes, according to the EU MAP and ICES MSY approach
(assuming that all catch is landed). Four species of sea-pen (Virgularia mirabilis, Funiculina
quadrangularis, Pennatula phosphorea and the deepwater sea-pen Kophobelemnon
stelliferum) were observed during the survey. Trawl marks were also observed on 20% of
the stations surveyed.Marine Institut
FU19 Nephrops Grounds 2023 UWTV Survey Report and catch scenarios for 2024
This report provides the main results of the fourteenth underwater television survey
of the various Nephrops patches in Functional Unit 19. The survey was multi disciplinary in nature collecting UWTV and other ecosystem data. In 2023 a total 42
UWTV stations were successfully completed. The mean density estimates varied
considerably across the different patches. The 2023 raised abundance estimate
showed a 15% decrease from the 2022 estimate and at 220 million burrows is below
the MSY Btrigger reference point (430 million). Using the 2023 estimate of abundance
and updated stock data implies catch in 2024 that correspond to the F ranges in the
EU multi annual plan for Western Waters are between 224 and 248 tonnes
(assuming that discard rates and fishery selection patterns do not change from the
average of 2020–2022). One species of sea pen was observed; Virgularia mirabilis
which has been observed on previous surveys of FU19. Trawl marks were observed
at 10% of the stations surveyed.Marine Institut

Scottish Inshore Fisheries Integrated Data System (SIFIDS): work package (2) final report WP2A: development and pilot deployment of a prototypic autonomous fisheries data harvesting system, and WP2B: investigation into the availability and adaptability of novel technological approaches to data collection
[Extract from Executive Summary]
To enhance sustainability and foster resilience within Scotland’s inshore fishing communities an effective system of collecting and sharing relevant data is required. To support business decisions made by vessel owners as well as informing fisheries managers and those involved in marine planning it will be vital to collect a range of information which will provide a robust understanding of fishing activity, the economic value of the sector and its importance within local communities.
The SIFIDS Project was conceived to assist in attaining these goals by working alongside fishers to develop and test technology to automatically collect and collate data on board vessels, thereby reducing the reporting burden on fishers. The project built upon previous research funded through the European Fisheries Fund (EFF) and was designed to deliver a step change in the way that inshore fisheries in Scotland could be managed in cooperation with the industry. The project focussed on inshore fishing vessels around Scotland, where spatio-temporal information on the distribution of vessels and associated fishing effort is data deficient.
The whole project was broken down into 12 highly integrated work packages. This is the integrated report for work packages 2A and 2B, entitled’ Development and Pilot Deployment of a Prototypic Autonomous Fisheries Data Harvesting System’ (2A) and ‘Investigation into the Availability and Adaptability of Novel Technological Approaches to Data Collection’ (2B).Publisher PD
