Wild European Eel: Conservation and Welfare Crisis

European eel populations have collapsed by over 90% since the 1970s. Eels face welfare threats from migration barriers, parasites, overfishing and pollution.

Key Facts

European eels are critically endangered, with populations at approximately 10% of historical levels
Eels are catadromous, migrating thousands of miles between European rivers and the Sargasso Sea
The eel swim bladder parasite Anguillicoloides crassus was introduced from Asia in the 1980s
River barriers prevent eel migration and are a primary driver of population collapse
Eels show pain responses and are likely sentient, raising welfare concerns in commercial fisheries

Welfare Considerations

European eels face an existential crisis combining habitat destruction, disease and overexploitation. Their welfare in commercial eel fisheries is poorly regulated despite evidence of sentience.

What You Can Do

Support eel pass installation on rivers to restore migration corridors
Avoid consuming glass eels or wild-caught European eel products
Advocate for stronger fisheries regulation protecting critically endangered eel stocks
