Marine turtles face cumulative threats from fisheries, plastic pollution and climate change. Conservation interventions that address individual welfare improve population recovery prospects.
Marine turtle welfare encompasses multiple threat categories. Entangled turtles experience severe stress, exhaustion and injury; those that survive may have amputated flippers affecting long-term ability to forage and reproduce. Plastic ingestion causes prolonged gastrointestinal suffering as blocked guts prevent nutrient absorption. Stranded turtles on cold-stunning beaches experience hypothermia and metabolic collapse. Rehabilitation centres that treat injured individuals serve both individual welfare and population conservation when success rates are sufficient. Climate feminisation threatens population viability through skewed sex ratios.
