Humpback Whale Entanglement in Fishing Gear

Humpback whales face serious welfare harm from entanglement in commercial fishing lines and nets, causing injury, chronic stress, and death across ocean habitats worldwide.

Key Facts

An estimated 300,000 whales and dolphins die annually from fishing gear entanglement
Humpbacks can carry entangled gear for months or years, causing deep wounds and starvation
Rope cuts into blubber and muscle as whales grow and drag gear
Disentanglement teams operate globally but reach only a fraction of entangled animals
Ropeless fishing gear technology is commercially available and under regulatory review
Ghost gear - lost or abandoned fishing equipment - continues to entangle wildlife long after use

Welfare Considerations

Entanglement causes prolonged suffering, including open wounds, restricted movement, malnutrition, and chronic stress. Animals may survive entanglement for years before succumbing. The process of disentanglement itself is stressful and dangerous for both whales and responders. Population-level reproductive impacts are significant since entanglement disproportionately affects adult females.

What You Can Do

Support ropeless or on-demand fishing gear adoption in your region
Back organizations like the Center for Coastal Studies that run disentanglement programs
Advocate for mandatory gear modifications in fisheries overlapping whale habitat
Choose seafood certified by programs that require low bycatch standards
Report entangled marine animals to local coast guard or wildlife rescue numbers
