Humpback whale populations have made remarkable recovery since the moratorium on commercial whaling, but entanglement, vessel strikes, and noise pollution continue causing welfare harm.
Entangled humpback whales suffer one of the most prolonged welfare harms documented in marine mammal research. Ropes embedded in skin and around flippers cause months of progressive injury, infection, and energy drain as whales drag gear behind them. Some entanglements ultimately prove fatal; others require complex at-sea disentanglement operations by trained teams. The recovery story of humpbacks demonstrates what is achievable with protective legislation - a model for other cetacean conservation.
