ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Biological characteristics and mortality of western butterfish (Pentapodus vitta), an abundant bycatch species of prawn trawling and recreational fishing in a large subtropical embayment [PDF]
The western butterfish (Pentapodus vitta) is numerous in the bycatch of prawn trawling and recreational fishing in Shark Bay, Western Australia. We have thus determined crucial aspects of its biological characteristics and the potential impact of fishing

Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska
ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

One-boat midwater trawling with unequal panelled trawl
Results of the comparative efficiency studies with 10.5 m equal panelled and 10.3 m unequal panelled midwater trawls operated from 10.9 m wooden trawler are presented. Out of the two nets, the latter proved to be relatively good for the capture of off bottom and column fishes like pomfrets, seer, lactarius, catfish, silver bar, ribbon fish and an ...

ABSTRACT Pacific cod (Gadus macrocephalus) are important predators of juvenile snow (Chionoecetes opilio) and Tanner crab (Chionoecetes bairdi) in the eastern Bering Sea (EBS), yet the relationship between cod–crab spatial overlap and total crab consumption is only partially understood.

Performance of pulse trawling compared to conventional beam trawling
A series of nine fishing trips with on board observers were carried out on MFV UK153 (PT1) and two beam trawlers (BT1, BT2) of comparative engine power and size to appraise the performance of pulse beam v.s. conventional tickler chain beam trawls. The main conclusions from this study are: 1.
