Sea turtles are among the most iconic marine species, facing threats from bycatch, plastic ingestion, climate change, and poaching — with significant individual welfare implications.
Sea turtle welfare encompasses the suffering of individual animals from plastic ingestion, entanglement, and disease as well as the population-level effects of conservation threats. Fibropapillomatosis tumours cause progressive debilitation that reduces swimming ability, vision, and feeding — a prolonged deterioration in welfare before death. Plastic ingestion, like in seabirds, causes false satiety and eventual starvation. Conservation measures that protect nesting beaches and reduce bycatch directly improve the welfare of individual sea turtles by reducing these sources of harm. Sea turtle rehabilitation programmes also provide welfare benefit to injured individuals while contributing to population recovery.
