Collaborative research: Development of a manual on elasmobranch handling and release best practices in tropical tuna purse-seine fisheries

摘要: The reduction of by-catch mortality is an objective the ecosystem approach to fisheries and a request made by consumers. Elasmobranchs, important component French tropical tuna purse seine fishery by-catch, are currently thrown back into sea. Fishers interact with various types elasmobranchs that range widely in size, weight shape, could pose degrees danger crew. A diversity discarding practices within fleet were reported, some considered suitable, others needed be adapted improved simply had banned. majority crews likely improve their handling if they presented practical suggestions quick easy. Combining scientific observations empirical knowledge from skippers crew, manual, providing appropriate ensure crew safety increase odds survival for released animals has been developed disseminated. Bringing these good onto decks fishing vessels should contribute vulnerable species. It would positively viewed consumers as act reduces fishing's footprint on environment promoting animal welfare which image industry. Mitigation research definition iterative process different complementary methods must carried out at levels significantly reduce by-catch.
