The return of large fish-eating raptors to British waters creates new welfare considerations for the fish they prey on, while reflecting broader ecosystem health and predator welfare recovery.
The welfare of fish caught by ospreys and sea eagles sits at the frontier of wild animal welfare ethics. Fish show nociceptive responses consistent with pain experience, and penetrating talon injury is likely to activate these systems. However, natural predation is a fundamental ecological process - attempting to prevent it would be both futile and ecologically harmful. The welfare framework most applicable here is one of ecological integrity: prey animals live in systems shaped by predation pressure, with behavioural adaptations that have evolved in response to it. The key welfare question is not whether predation happens, but whether prey population welfare is maintained through healthy, productive habitats that allow animals to express natural behaviours and maintain good body condition between predation events.
