Loggerhead Sea Turtle Bycatch and Welfare

Loggerhead sea turtles face substantial mortality from longline and trawl fisheries bycatch, with drowning, hook injuries, and barotrauma causing significant individual suffering and population-level threats.

Key Facts

Loggerhead sea turtles are listed as vulnerable globally, with some populations critically endangered
Longline fishing bycatch kills an estimated tens of thousands of loggerheads annually worldwide
Turtles drowned in fishing gear suffer oxygen deprivation over periods of minutes to hours
Circle hooks reduce sea turtle bycatch by 90% compared to J-hooks on pelagic longlines
Turtle Excluder Devices (TEDs) in shrimp trawls reduce turtle bycatch by up to 97%
US law mandates TED use in shrimp trawl fisheries, but international compliance is inconsistent
Injured turtles that survive bycatch interactions often have permanent hook damage, flipper entanglement scars, or buoyancy disorders

Welfare Considerations

Drowning in fishing gear is a death by suffocation - a prolonged and distressing process for air-breathing reptiles. Turtles that survive longline entanglement may have hooks embedded in the esophagus, stomach, or flippers causing chronic pain and impaired feeding. Buoyancy disorders from barotrauma leave turtles unable to dive normally. The technological solutions - circle hooks, TEDs, modified gear - exist and are proven. The barrier is primarily economic and regulatory compliance, not technological.

What You Can Do

Choose certified sustainable seafood from fisheries with documented bycatch reduction programs
Support SeaTurtleConservancy.org and Oceana campaigns for mandatory bycatch reduction gear
Advocate for international adoption of circle hook requirements in longline fisheries
Report injured or entangled turtles to national wildlife rescue hotlines immediately
Reduce single-use plastic use that degrades into debris turtles ingest or become entangled in
