Marine Turtle Bycatch Welfare: Reducing Incidental Capture in Fisheries

Marine turtle bycatch in fishing operations causes significant welfare harm to individuals and conservation harm to endangered populations.

Key Facts

All seven marine turtle species are threatened or endangered, partly due to bycatch mortality
Long-line fisheries are a major bycatch threat for leatherback and loggerhead turtles
Turtle Excluder Devices (TEDs) reduce bycatch by up to 97% in trawl fisheries
Handling and release protocols for incidentally caught turtles significantly affect survival rates
Turtles caught in nets can drown within minutes - observer programs and rapid response protocols are critical
Cormorant and pelican entanglement in ghost fishing gear is a related bycatch welfare problem

Welfare Considerations

Marine turtle bycatch welfare occurs at the intersection of individual animal suffering and species conservation emergency. Turtles caught in nets experience drowning if not released quickly, and even released turtles may suffer internal injuries, cold stunning, or physiological stress that causes delayed mortality. The conservation dimension magnifies welfare significance - each bycatch event affects an individual of a species where individual survival is critical for population recovery. Solutions like TEDs and circle hooks are known and available, making continued bycatch mortality a preventable welfare and conservation failure.

What You Can Do

Choose seafood certified by programs requiring turtle-safe fishing gear and practices
Support mandatory TED requirements in all trawl fisheries operating in turtle habitat
Advocate for observer programs that monitor bycatch and ensure appropriate handling
Support turtle rescue and rehabilitation programs for bycatch-injured turtles
Reduce seafood consumption to decrease demand pressure on fisheries with high bycatch rates
Donate to organizations working on bycatch reduction technology and policy
