Farmed Eel Welfare in Aquaculture

Eel farming faces unique welfare challenges including the inability to breed eels in captivity and the welfare impacts of wild glass eel capture.

Key Facts

European and Japanese eels cannot be bred in captivity — all farmed eels begin as wild-caught juvenile glass eels or elvers
European eel is Critically Endangered — glass eel capture for farming is contributing to population decline
Eels are highly sensitive to handling stress and show strong avoidance responses to capture and crowding
Slaughter methods for eels including live gutting and CO2 stunning cause prolonged suffering
Electrical stunning followed by rapid chilling is recommended by welfare scientists as the most humane eel slaughter method

Welfare Considerations

Eel welfare involves a fundamental ethical problem: there is no closed captive breeding cycle. Every farmed eel begins as a wild-caught animal removed from a critically endangered wild population. The welfare harms of capture, transport, and farming are layered on top of serious conservation concerns. The combination makes eel farming one of the most ethically problematic aquaculture sectors from both welfare and sustainability perspectives.

What You Can Do

Reduce eel consumption significantly given both welfare and conservation concerns about European eel
Avoid unagi (freshwater eel) sushi and other eel products unless sourced from certified sustainable operations
Support campaigns for better regulation of glass eel capture and welfare standards in eel aquaculture
Choose farmed eel from operations using electrical stunning if consumption is unavoidable
