Marine Turtle Welfare and Conservation: Six Species in Crisis

All seven marine turtle species are threatened or endangered. Their welfare is shaped by bycatch, plastic ingestion, climate change affecting nesting beaches, and light pollution disrupting hatching behaviour.

Key Facts

Six of seven marine turtle species are classified as Endangered or Vulnerable on the IUCN Red List
Leatherback turtles migrate to British and Irish waters during summer — the UK northernmost regularly visiting marine turtle
Marine turtles frequently ingest plastic bags mistaken for jellyfish — causing gut blockage, perforation, and death
Longline and trawl bycatch kills an estimated 85,000 marine turtles annually — a primary cause of adult mortality
Light pollution on nesting beaches disorients hatchlings toward artificial light rather than the sea — causing mass stranding
Warming sea temperatures are feminising turtle populations — sand temperature during incubation determines sex ratio
Turtle excluder devices in shrimp trawl nets reduce bycatch without significant loss of target catch
Conservation programmes for nesting beaches including shade provision and hatchling guidance have measurable recovery effects

Welfare Considerations

Marine turtle welfare involves both the immediate suffering of bycaught, entangled, or plastic-ingested individuals and the longer-term population consequences of threats that reduce reproductive success. Individual turtles that ingest significant quantities of plastic experience prolonged gastrointestinal suffering. Those caught in fishing gear may drown or suffer crushing injuries. Hatchlings disoriented by coastal light pollution die from exhaustion and predation on land. The welfare and conservation agendas for marine turtles are fully aligned — addressing bycatch, plastic pollution, and light pollution simultaneously improves individual welfare and population viability.

What You Can Do

Reduce single-use plastic consumption and participate in beach cleans to reduce marine plastic pollution
Support Turtle Excluder Device requirements in shrimp fisheries operating in turtle habitat
Advocate for dark sky policies near nesting beaches including shading of artificial lights during nesting season
Donate to Sea Turtle Conservancy and Oceana marine turtle protection programmes
Engage with holiday companies to select turtle-friendly accommodation that respects nesting beaches
Report any stranded or entangled turtles in UK waters to BDMLR for expert assessment
