Sea turtles face welfare threats from plastic ingestion, boat strikes, entanglement, and cold-stunning events. Rehabilitation programs and bycatch reduction are the primary intervention points for improving their welfare.
Sea turtle welfare involves both acute crisis response — cold-stun rescues, entanglement response, injury rehabilitation — and the systemic challenges of plastic pollution and fisheries bycatch. Cold-stunned turtles experience a medical emergency analogous to hypothermia in mammals, requiring controlled rewarming and intensive supportive care. Fibropapillomatosis, whose spread is linked to coastal water quality degradation, causes tumors that impair vision, swimming, and feeding, producing chronic suffering. Bycatch mortality in longline fisheries represents the largest scale welfare and conservation threat — circle hooks and modified gear reduce sea turtle bycatch by up to 90%, making gear modification one of the highest-impact interventions available.
