The authors tested the effectiveness of 'scarybird', a visual deterrent, to reduce seabird bycatch in bottom gillnet fisheries in Portugal. The scarybird is a raptor-shaped aerial device that is flown behind the stern of the boat up to ~7m above sea level.

This paper suggests guidelines for evaluating artificial light in bycatch reduction devices (BRL) using a standardized, collaborative, multidisciplinary approach. The purpose is to improve data consistence to support future meta-analyses and inter-study comparisons, and to highlight areas where further research is needed most urgently, as BRLs are a promising and rapidly moving area of bycatch mitigation.

The authors modeled 28 years of data to estimate the impact of entanglement on female North Atlantic right whale health, survival and reproduction. Results show that entangled whales were drastically more likely to experience negative health impacts, including declines in body condition and lower survival rates. Furthermore, whales in poor body condition were not reproductive- between 1994 and 2021, entanglements reduced the expected number of calves by 12.9% and the number of living females by 18.5%.
