Humpback whale populations have recovered dramatically from commercial whaling, but welfare threats from ship strikes, fishing gear entanglement, and underwater noise pollution persist.
Humpback whale welfare success demonstrates what conservation action can achieve at population scale. However, individual welfare threats remain serious. Entanglement events are particularly severe - whales may drag heavy gear for weeks or months, causing deep rope wounds, infection, and eventual starvation. Ship strikes cause immediate traumatic injury. Chronic noise exposure disrupts the communication networks that allow whales to coordinate feeding and socialise - a welfare harm that is harder to measure but significant. Whale disentanglement teams provide direct welfare intervention at high risk to human responders.
