Marine Mammal Entanglement Response

Marine mammal entanglement in fishing gear and marine debris requires specialized response teams with appropriate training and equipment to free animals safely.

Key Facts

Large whale disentanglement requires specialized teams using custom cutting equipment from boats
Entangled seals can often be freed from debris if approached carefully on beaches
Entanglement causes chronic wounds and behavioral changes that affect foraging success
NOAA coordinates large whale entanglement response across US waters with trained response networks
Self-entanglement attempts without training cause additional injury and distress to animals

Welfare Considerations

Marine mammal entanglement response is one of the most direct welfare interventions available for wild animals, freeing individuals from conditions that would otherwise cause prolonged suffering and death. The welfare difference between a whale freed from entanglement early versus one carrying gear for months — with progressive wounds, behavioral changes, and energy depletion — is enormous. However, response requires specialized training and equipment, and unskilled attempts to assist entangled marine mammals can worsen their condition. Supporting trained response capacity and reporting is the appropriate public contribution.

What You Can Do

Report entangled marine mammals to NOAA or local response networks immediately — do not attempt self-rescue
Support NOAA disentanglement programs and response network funding
Donate to organizations providing training and equipment for marine mammal entanglement response
Advocate for fishing gear modifications that reduce entanglement risk
Never attempt to free an entangled large whale yourself — support trained responders to access the animal
