All seven sea turtle species are threatened or endangered, and fisheries bycatch is the most significant human-caused mortality factor affecting their populations globally.
Sea turtle bycatch welfare harm is severe. Turtles caught in nets or on hooks may drown if unable to surface, or suffer hook injuries and entanglement wounds requiring treatment. Long entanglement periods cause exhaustion and physiological stress before death or release. TEDs and circle hooks are proven technologies that dramatically reduce both mortality and sublethal welfare harm. The continued failure to universally adopt these technologies in fisheries where sea turtles are present represents a preventable welfare failure at enormous scale.
