Sea Turtle Welfare: Threats and Conservation

Sea turtles face multiple anthropogenic welfare threats including bycatch, plastic ingestion, coastal development, and climate change, requiring comprehensive conservation and welfare responses.

Key Facts

Seven species of sea turtle are found globally, all threatened or endangered
An estimated 250,000 sea turtles are captured as bycatch in fisheries each year
Plastic ingestion causes intestinal blockages and buoyancy disorders that are often fatal in sea turtles
Artificial lighting disrupts nesting and disorientation of hatchlings navigating to the sea
Climate change is shifting nesting beach temperatures, affecting sex ratios of turtle populations

Welfare Considerations

Sea turtle welfare encompasses both the suffering of individual animals from acute threats and the long-term viability of populations facing compounding anthropogenic pressures. Bycatch entanglement causes drowning and drowning-related injuries in turtles that can be significantly reduced through circle hooks, excluder devices, and fishery management measures. Plastic ingestion causes prolonged suffering through blockage and buoyancy syndrome. Nesting beach disturbance from lighting and development disrupts the reproductive success on which population recovery depends. Individual welfare and conservation goals align closely for sea turtles: protecting animals from immediate suffering also protects the populations that recovery requires.

What You Can Do

Support circle hook requirements in sea turtle bycatch fisheries through certification choices
Reduce plastic waste, particularly single-use plastics that reach marine environments
Support sea turtle nesting beach protection through conservation organisations
Volunteer with turtle monitoring programmes if you live in or visit nesting range countries
Advocate for sea turtle excluder devices as mandatory requirements in high-risk fisheries
