Cormorant Double-Crested Conservation

Double-crested cormorants face conflicting pressures from recovered populations and fishery conflicts requiring evidence-based management.

Key Facts

Double-crested cormorant populations recovered after DDT was banned
They are now subject to lethal control in some areas due to fishery impacts
Evidence of their impact on fish stocks is mixed and context-dependent
Non-lethal deterrents can be effective in many situations

Welfare Considerations

Lethal control programs targeting double-crested cormorants kill large numbers of birds based on contested evidence of their fishery impact. Colony disruption methods including egg oiling cause suffering in breeding adults and developing chicks. Non-lethal deterrents including exclusion zones and harassment can reduce conflict without killing. Evidence-based management is more effective and welfare-positive than reactive culling.

What You Can Do

Support evidence-based rather than reactive cormorant management
Advocate for non-lethal deterrents as the primary response to fishery conflicts
Back research into actual cormorant impacts on fish stocks
Support habitat improvements for fish populations rather than cormorant control
