This study recorded and analyzed vocalizations of green sea turtles off the Carribbean island of Martinique, and identified which sounds seemed to be linked to flight, fear, and social aspects. When these recordings of sea turtles were played to wild sea turtles, they demonstrated behavioral responses (vigilance and/or escape) to the sounds they produce, suggesting that acoustic deterrents may be effective to reduce sea turtle bycatch. Sea turtles did not respond to synthetic or geophonic noises.

This article summarizes cetacean strandings along the Bulgarian coast of the Black Sea between 2010-2022; of a total 1,528 strandings, evidence of bycatch was present in 80 animals. The presence of strandings with signs of bycatch even during the seasonal bans on turbot fishing suggests that IUU fisheries may be operating.

 This study assesses bycatch and depredation  by sharksand odontocetes in the French Polynesian longline fishery between 2000 and 2018, and finds that less than 2% of the catch had been depredated, but shark bycatch was high (20,000 sharks annually, 0.5 shark every 1000 hooks). Conversely, odontocete bycatch was comparatively low  (13 occurrences in 18 years), though reporting may have been inaccurate. This is important as there is a plan to  double offshore fisheries production in the French Polynesia EEZ by 2027.

This is a meta-analysis that quantified the effects of 42 technical measures on the target catch and the bycatch of seabirds, elasmobranchs, marine mammals and sea turtles, evaluating which methods were most effective at mitigating bycatch of each fauna group. Overall, mitigation methods reduced bycatch while having no statistically significant effect on the target catch, and sensory-based measures (e.g. pingers, blue-dyed bait) generally outperformed physical-based measures (e.g. circle hook, larger mesh) in reducing  bycatch.
