High-grading is the decision by fishers to discard fish of low value that allows them land more valuable fish. A literature review showed high-grading reported in commercial and non-commercial fisheries around world, although number observations small. occurs are restricted their total catch due management, market or physical constraints. Using mixed flatfish fishery as a model system, dynamic state variable simulation certain grades throughout year when ex-vessel price low. increases with...
Climate change continues to alter the productivity of commercially and culturally important fisheries with major consequences for food security coastal economies. We provide first, multi-model projections changes in distribution 18 key fish stocks across seven European regional seas spanning Mediterranean Arctic, using 11 state-of-the-art bio-ecological models. Our indicate species- region-specific abundance distributions these by mid- late 21st century. The varied responses are caused...

Climate change is anticipated to have long-term and widespread direct consequences for the European marine ecosystems subsequently fishery sector. Additionally, many socio-economic political factors linked climate scenarios will impact future development of fishing industries. Robust projection modeling bioeconomic on sector must identify all these their potential interaction. In this study, four socio-political developed in EU project CERES (Climate aquatic RESources) were operationalized...
Abstract This paper presents and evaluates a method for detecting counting demersal fish species in complex, cluttered, occluded environments that can be installed on the conveyor belts of fishing vessels. Fishes belt were recorded using colour camera detected deep neural network. To improve detection, synthetic data generated rare species. The fishes tracked over consecutive images multi-object tracking algorithm, based multiple observations, was determined. effect data, amount occlusion,...
Abstract The International Council for the Exploration of Sea (ICES) typically provides advice on fishing opportunities a stock-by-stock basis. Nevertheless, levels total allowable catch (TAC) are sometimes set collection stocks and species (i.e. common TAC). An explicit expectation these is that landings will scale with ICES advice, especially when used to calculate TAC. This tested skates rays in Northeast Atlantic, spanning 26 stocks, 8 species, 3 ecoregions. Using data from 2016 2022, we...

The beam trawl fishery targeting sole is known for their substantial bycatch of flatfish below the minimum landing size. Pulse trawls were developed to improve selectivity by replacing mechanical stimulation with electrical which immobilises fish in front footrope. Results are presented an experiment on board a commercial pulse trawler studying effect footrope and cod-end three species - (Solea solea), plaice (Pleuronectes platessa) dab (Limanda limanda) 29 paired hauls alternating between...
We measured discards survival probabilities of thornback ( Raja clavata) and spotted skate montagui ) in tickler chain beam trawling (5 trips, n = 183 for skate, 137 skate), pulse (9 94 skate) flyshoot fishieres (4 24 skate). Survival were by captive observation 15 to 25 days post catch. All fishery operations conducted the southern North Sea (ICES division 27.4.c) Eastern English Channel 27.7.d) according regular commercial practices fishing vessels. Trips spread out over seasons account...
