Hammerhead sharks face severe pressure from fishing, finning, and habitat loss. Their unique social behavior and specialized sensory anatomy make their welfare and conservation particularly significant.
Hammerhead shark welfare is particularly focused on the finning issue, which represents one of the most acute and extended individual welfare harms in any fishery. Finning involves the amputation of all fins — often while the shark is still alive and conscious — before the living animal is returned to the water. The finned shark, unable to swim effectively and in severe pain from the wounds, slowly sinks, eventually dying from drowning, blood loss, or predation. This process takes many hours and represents an extreme welfare harm. The scale of the practice — millions of sharks annually — and the social behavior of hammerheads, which aggregate in schools making them efficiently targeted, means that this welfare harm is occurring at massive scale. Fins-naturally-attached regulations that require sharks to be landed whole eliminate the immediate welfare incentive to fin at sea and have been effective where enforced. Consumer demand reduction for shark fin products in major consumption markets is the other essential component, as declining market value removes the economic driver for the fishery.
