Sea lions and fur seals interact with commercial fisheries and coastal tourism in ways that create welfare conflicts requiring evidence-based management.
Sea lion welfare intersects with human economic interests at multiple points. Fishers who see them as competitors use illegal shooting, entanglement in gear, and boat propeller encounters — each causing injury or death. Poorly managed tourism creates stress during critical resting and nursing periods. At the same time, sea lion populations that have recovered from near-extinction now face secondary challenges from fishery depletion of their prey base. Individual welfare and population conservation are inseparable for species whose recovery creates conflict with established human interests.
