Humpback whales have recovered remarkably from commercial whaling, but face ongoing welfare challenges from entanglement in fishing gear, vessel strikes, and noise pollution that disrupts their complex communication.
Entangled whales suffer profoundly. The fishing gear wraps around their bodies, cutting into flesh, restricting movement, and often embedding hooks or lines deeply into tissue. These animals may drag thousands of pounds of gear for months, burning energy reserves while unable to feed normally. The resulting starvation, infected wounds, and exhaustion can be fatal. Even non-lethal entanglements cause weeks of suffering. Vessel strikes cause immediate traumatic injury - whales struck by large ships may suffer broken bones, internal bleeding, and lacerations from propellers. The noise pollution from shipping traffic reduces humpback whales' ability to communicate for mating, social bonding, and coordination - a form of chronic environmental stressor affecting their psychological wellbeing.
