Entanglement in fishing gear is one of the leading causes of injury and death for large whales worldwide, causing prolonged suffering and population-level impacts on already threatened species.
Entanglement represents one of the most prolonged and severe welfare crises facing wild marine mammals. Whales ensnared in ropes, nets, and crab pot lines experience sustained physical trauma and metabolic stress that can last for months. The gear wraps tightly around flippers, mouths, and bodies, causing deep wounds that become infected. Dragging the weight of fishing equipment depletes energy reserves critical for migration and reproduction. Even whales that survive entanglement may suffer long-term health consequences, reduced reproductive success, and premature death. The welfare harm is compounded by the fact that these animals are highly sentient, social beings capable of complex suffering.
