Humpback whale populations have recovered significantly since the end of commercial whaling, but they continue to face serious threats from entanglement, vessel strikes, and climate change.
Despite population recovery, individual humpback welfare remains seriously compromised by human activities. Entanglement in crab pot lines and gillnets causes prolonged suffering, exhaustion, and drowning - entangled whales may struggle for days or weeks before death or rescue. Ship strikes cause blunt force trauma and propeller injuries. Noise pollution from shipping impairs communication and navigation. Disentanglement teams perform vital welfare interventions, but the scale of entanglement far exceeds rescue capacity. Reducing fishing gear entanglement risk through rope-less gear technology represents the most impactful near-term welfare intervention.
