Sea Turtle Conservation and Bycatch Welfare

Sea turtles are ancient marine reptiles threatened by fisheries bycatch, habitat loss, and climate change. Reducing bycatch through modified gear and protected areas prevents suffering across all seven sea turtle species.

Key Facts

Six of seven sea turtle species are threatened or endangered; all are protected under the US Endangered Species Act
Longline fishing bycatch kills approximately 200,000 sea turtles annually globally
Circle hooks reduce sea turtle bycatch by 80-90% compared to traditional J-hooks in longline fisheries
Turtle Excluder Devices (TEDs) in shrimp trawls reduce sea turtle bycatch by 97%
Beach lighting on nesting beaches disorients hatchlings and adults; sea turtle-friendly amber lighting reduces this harm
Climate change shifts nesting beach temperatures, causing sex ratio skew toward females in some populations
Plastic ingestion affects nearly all examined sea turtles; entanglement in fishing gear and plastic causes suffocation
Sea turtle nesting beach protection programs have contributed to significant loggerhead recovery in Florida

Welfare Considerations

Sea turtle bycatch welfare involves multiple forms of suffering: drowning in submerged nets and longlines, physical injury from hooks and entanglement, and the stress of capture and handling during discard. Circle hooks represent one of the most clearly documented, cost-effective welfare improvements in any fishery: they dramatically reduce the number of turtles hooked and the severity of injury when hooking occurs because of their curved shape that reduces deep ingestion. The welfare case for universal adoption of circle hooks and TEDs is supported by decades of research and aligns with conservation goals, yet adoption remains incomplete globally. This gap between available solutions and their adoption is a characteristic welfare challenge in wild animal conservation.

What You Can Do

Choose seafood from fisheries using circle hooks and turtle excluder devices where these are available
Support the Marine Stewardship Council certification program that increasingly includes bycatch reduction criteria
Participate in beach cleanup programs that remove plastic waste threatening sea turtles
Support sea turtle-friendly lighting ordinances in coastal communities near nesting beaches
Donate to sea turtle conservation organizations including the Sea Turtle Conservancy
Advocate for international treaty requirements mandating turtle-safe fishing gear in all major fishing nations
