This study evaluated the cetacean interactions with a bottom-set net fishery along the mainland Portuguese Southern coast (Algarve) from 2018-2022. Depredation by bottlenose dolphins occurred in 17.7% of hauls, while bycatch occurred in <1%. Depredation was elevated in the spring and winter months and in gears targeting red mullet and hake.

This is a summary of case studies that were reviewed for efficacy of mitigation methods in gillnet fisheries for reducing seabird bycatch, focusing specifically on time-area restrictions and gear-switching. Both methods show promise to reduce bycatch and meet conservation standards, but a holistic approach that considers seabird behavior, target species activity, and socioeconomic impacts is encouraged.

Seabird bycatch in gillnets is a worldwide problem with few if any available mitigation tools. LED lights attached to the gillnets have been suggested as a potential solution, and a study in Peru showed promising results where bycatch of diving seabirds was reduced by adding LED lights to bottom set gillnets. In this study the potential bycatch reduction of LED lights was tested in a set gillnet fishery that targets Atlantic cod Gadus morhua in Iceland.

This field study evaluated the use of green LED handline modifications (visual deterrent) on Atlantic cod (Gadus morhua) gillnets to reduce bycatch of wolffish. Experiments were performed on three separate commercial fishing vessels in Mission Bay, Canada between September and November 2020, and experimental LED lights were applied to vessels rather than individual lines. There was no significant impact of the lights to either target catch or bycatch, but limited statistical analyses suggest that the use of green LED lights did reduce bycatch of Atlantic wolffish (Anarhichus lupus).
