Wild Cormorant Welfare and Aquaculture Conflict

Cormorants are protected birds that cause damage to fish farms and fisheries. Welfare-positive conflict management approaches reduce conflict without population suppression.

Key Facts

Great cormorant populations have recovered significantly in Europe following protection
Cormorants cause economic damage to aquaculture and river fisheries through fish predation
Scaring devices, netting, and visual deterrents reduce cormorant impact without lethal control
Licensed lethal control exists in some jurisdictions but has limited effectiveness on populations
Fishery management that maintains prey fish abundance reduces the attractiveness of protected areas to cormorants

Welfare Considerations

Cormorant welfare involves the tension between protected species status and legitimate economic impacts on fisheries. Non-lethal deterrence through scaring and netting provides welfare-positive alternatives to lethal control that address the economic impact without welfare harm to birds. Fishery management that maintains natural prey abundance is the most sustainable systemic approach.

What You Can Do

Support non-lethal cormorant deterrence investment in aquaculture operations
Advocate for fisheries management that maintains natural prey fish populations reducing cormorant attraction
Report cormorant welfare concerns including illegal persecution to wildlife crime authorities
Support wildlife management approaches that address conflict causes rather than symptom control through culling
