Wild Sea Turtle Welfare: Bycatch, Pollution, and Nesting

All seven species of sea turtle are threatened or endangered, with bycatch, plastic pollution, climate effects on nesting beaches, and direct harvest creating significant welfare and conservation challenges.

Key Facts

All seven sea turtle species are listed as Vulnerable, Endangered, or Critically Endangered on the IUCN Red List
An estimated 250,000 sea turtles are captured incidentally in fishing gear annually
Turtle Excluder Devices (TEDs) in shrimp trawls dramatically reduce sea turtle bycatch and are required in US waters
Plastic ingestion is widespread — over 50% of sea turtles have ingested plastic in some studies
Climate change is feminizing turtle populations — nest temperature determines sex, and hotter beaches produce more females
Artificial lighting on beaches disorients hatchlings that navigate by moonlight reflected on water
Fibropapillomatosis — a tumor disease associated with pollution — is increasing in green turtle populations
Many populations have shown recovery under legal protection — demonstrating that conservation works

Welfare Considerations

Sea turtles caught in trawl nets drown over minutes to tens of minutes while unable to surface — a prolonged and distressing death. Turtles that survive capture often have injuries from the net, propeller strikes, or hooks. Plastic ingestion causes intestinal obstruction, perforation, and a prolonged death through starvation or sepsis. Fibropapillomatosis causes large tumor growths that impair swimming, vision, and feeding — affected turtles experience progressive debilitation. Artificial beach lighting disorients hatchlings, causing them to head inland toward roads rather than the ocean — a death that would not occur without human infrastructure. Many of these welfare harms are directly preventable through existing technology and regulations.

What You Can Do

Reduce single-use plastic use and participate in coastal cleanup events
Support turtle-safe seafood by choosing products from fisheries using Turtle Excluder Devices
Choose dark-sky friendly lighting near coastal nesting beaches
Support sea turtle nest monitoring and hatchling protection programs
Donate to sea turtle conservation organizations including Sea Turtle Conservancy
