Here’s the recipe for saving sea turtles from drowning in the longline fishery. Switch out the classic J hooks for circular hooks. Add a little training and the tools to release turtles accidentally hooked.
A new report by the World Wildlife Fund and the Inter-American Tropical Tuna Commission (IATTC) finds the new hooks dramatically reduce the bycatch of marine turtles without impacting fishing activity. They analyzed 4 years of data from 8 Eastern Pacific countries: Mexico, Panama, Costa Rica, El Salvador, Guatemala, Colombia, Ecuador, and Peru. They found up to 89% reductions in the marine turtle bycatch per thousand hooks, and that 95% of all turtles caught in longline fishing were recovered alive. Circle hooks performed as well as J hooks in the catch rates of tuna, billfishes and sharks fishery.
