Pelagic Longline Turtle Mitigation Research: Design Impacts & Catch Rates

This research analyzes the efficacy of different hook designs in reducing sea turtle bycatch and their impact on catch rates of target species like swordfish and bigeye tuna. The study results show reduction rates for loggerhead and leatherback turtles, providing valuable insights for sustainable fishing practices.
