Sea Turtle Bycatch and Welfare: A Global Conservation and Suffering Issue

Hundreds of thousands of sea turtles are caught as bycatch in fishing gear each year, causing death, injury, and drowning. Mitigation measures can dramatically reduce this welfare and conservation harm.

Key Facts

All seven sea turtle species are threatened or endangered; bycatch is among the leading anthropogenic causes of mortality
Longline, trawl, and gillnet fisheries are the primary sources of sea turtle bycatch
Turtles caught in trawl nets drown if they cannot surface to breathe — death takes minutes to hours
Turtle excluder devices (TEDs) in trawls reduce turtle capture by over 97% without significantly reducing target fish catch
Circle hooks in longline fisheries reduce sea turtle bycatch by up to 90% compared to J-hooks
Many countries now mandate TEDs and circle hooks; compliance and enforcement remain challenges

Welfare Considerations

Sea turtle bycatch causes significant welfare harm beyond its conservation impact. Drowning in trawl nets is a slow, distressing death. Turtles entangled in longline gear may be dragged for hours before retrieval, sustaining physical injury and prolonged stress. Even turtles released alive may die later from injuries or physiological stress. Welfare-centred fisheries management requires adoption of proven bycatch reduction technologies (TEDs, circle hooks), robust enforcement, and rapid release protocols for live-caught turtles to maximise survival. Both conservation and welfare arguments converge on the same interventions.

What You Can Do

Choose seafood certified by Marine Stewardship Council or equivalent schemes with bycatch standards
Support campaigns for mandatory TEDs and circle hooks in fisheries with known sea turtle bycatch
Donate to sea turtle conservation organisations monitoring bycatch and advocating for mitigation
Report sea turtle strandings to local wildlife authorities — data supports conservation efforts
Engage retailers and seafood companies about their bycatch reduction policies in their supply chains
