Sea Turtle Bycatch: Welfare and Conservation Impacts

Sea turtle bycatch in commercial fisheries represents both a significant conservation crisis and a welfare problem, with thousands of sea turtles entangled annually in fishing gear designed for other species.

Key Facts

All seven sea turtle species are endangered or threatened, with bycatch representing one of the primary anthropogenic mortality sources
Longline fishing gear entangles sea turtles by the thousands annually — leatherback and loggerhead turtles are particularly vulnerable
Turtle Excluder Devices (TEDs) reduce sea turtle bycatch in trawl fisheries by up to 97% while allowing target species to pass through
Circle hooks in longline fisheries reduce sea turtle interaction rates compared to J-hooks without substantially reducing target catch efficiency
Post-interaction survival rates vary significantly depending on how quickly turtles are detected and whether appropriate release protocols are followed

Welfare Considerations

Sea turtle bycatch welfare is compounded by the protracted suffering involved — turtles entangled in fishing gear may struggle for extended periods before drowning or reaching the surface to breathe. When incidentally caught, handling and release protocols dramatically affect survival outcomes. Bycatch reduction technology exists and works — TEDs and circle hooks have demonstrated effectiveness at meaningful scale. Implementing these solutions requires regulatory will and commitment to enforce bycatch reduction requirements throughout global fisheries.

What You Can Do

Choose seafood certified by schemes with rigorous bycatch reduction standards for non-target species
Support international regulatory frameworks requiring bycatch reduction technology in fisheries operating in sea turtle habitat
Learn about sea turtle rescue organizations providing rehabilitation for bycatch-affected individuals
Advocate for observer requirements on fishing vessels to enable accurate bycatch monitoring and accountability
