Bycatch trend and its fate of the Spanish-owned tuna purse seiners fleet from the Atlantic and Indian oceans: Impacts of the implementation of good practices

This study examines the fate of species caught as bycatch in the tropical tuna purse seine fishery across the Atlantic and Indian Oceans from 2003 to 2022, focusing on the impact of the industry-implemented Code of Good Practices (CGP) and bycatch mitigation measures from Tuna Regional Fisheries Man...
