How Do We Minimize the Impact of Tuna Fishing on Manta and Devil Rays? Just Ask Fishers.

Fishers offer creative insight to reduce manta and devil ray bycatch

How do we protect vulnerable species from commercial fisheries?

In a new blog for ISSF, Melissa Cronin, doctoral student and Grand Prize winner in ISSF’s International Seafood Sustainability Foundation (ISSF) Seafood Sustainability Contest, reviews her collaborative work with purse seine vessel skippers and crew on handling-and-release methods to reduce the mortality of manta rays and devil rays incidentally caught during fishing.

Saving the Mobula Rays Poster: Eastern Pacific Ocean

A poster for tuna fishers shows five ray species found in Eastern Pacific tuna fisheries. It also provides location and life-cycle information and illustrates “acceptable” and “not acceptable” handling and release techniques to reduce ray bycatch.
