Cormorant and Fishery Conflicts: Finding Humane Coexistence Solutions

Conflicts between cormorants and fisheries have led to large-scale lethal control programs. Humane, evidence-based approaches offer more effective and ethical alternatives.

Key Facts

Great cormorant populations recovered strongly following pesticide bans in Europe
Cormorant predation on fisheries is often overstated in economic damage assessments
Hazing, netting, and flock dispersal can reduce cormorant impact without lethal control
Lethal control often requires ongoing culling as other birds fill vacated territories
Cormorants are protected under the EU Birds Directive and US Migratory Bird Treaty Act

Welfare Considerations

Cormorants have become scapegoats for fishery declines driven primarily by overfishing and habitat degradation. Lethal control programs — some involving shooting tens of thousands of birds — cause substantial suffering and rarely achieve lasting fishery benefits since new birds reoccupy territories. Evidence-based conflict management focuses on hazing during sensitive periods, protecting key fishing areas with deterrent systems, and improving fish habitat quality to address the underlying productivity issues. Coexistence is both possible and more cost-effective than ongoing lethal programs.

What You Can Do

Oppose lethal cormorant control programs lacking strong evidence of efficacy
Support research into non-lethal cormorant conflict management techniques
Advocate for independent ecological assessment before authorizing culls
Reduce fish consumption to lower fishing pressure that creates competition with cormorants
Support habitat restoration that improves fish population resilience
