Cormorant Management and Welfare

Cormorant population management involves lethal and non-lethal methods that raise welfare questions.

Key Facts

Great cormorant populations have recovered strongly in Europe following protection
Fishing industry pressure drives lethal culling programs in several countries
Egg oiling and nest disturbance are used as non-lethal population management tools
Non-lethal methods require sustained implementation to be effective

Welfare Considerations

Cormorant management creates welfare tensions between birds and commercial fisheries. Lethal culling causes death and in some cases wounding of birds not immediately killed. Egg oiling causes embryo death at a developmental stage. Nest disturbance causes abandonment and chick mortality. The welfare case against lethal management is stronger than against the alternatives, but all methods have welfare costs.

What You Can Do

Support non-lethal cormorant management methods over lethal culling
Advocate for evidence-based assessment of cormorant impact before management interventions
Engage with the genuine economic interests of fishing communities to find sustainable solutions
Support cormorant population monitoring to calibrate management responses
