Cost‐effective mitigation strategies to reduce bycatch threats to cetaceans identified using return‐on‐investment analysis

Globally, fisheries bycatch threatens the survival of many whale and dolphin species. Strategies for reducing bycatch can be expensive. Management is inclined to prioritize investment in actions that are inexpensive, but these may not be the most effective. We used an economic tool, return‐on‐investment, to identify cost‐effective measures to reduce cetacean bycatch in the trawl, net, and line fisheries of Australia. We examined 3 management...
