Farmed Eel Welfare and the Critically Endangered European Eel

European eel aquaculture depends entirely on wild-caught glass eels because eels cannot be bred in captivity, creating a welfare and conservation conflict.

Key Facts

European eels are Critically Endangered with populations at around 10% of historical levels
All farmed European eels start as wild-caught glass eels (juveniles) since breeding in captivity has not been achieved
Glass eel collection competes directly with natural recruitment to rivers, worsening the conservation crisis
Eels in aquaculture are kept at high densities and show significant stress responses to handling
The eel farming industry is economically significant in the Netherlands, Denmark, and other European countries
Sustainable alternatives including Japanese eel and farmed trout are available substitutes for European eel products

Welfare Considerations

Farmed European eels exist at the intersection of a welfare and conservation crisis. They are raised in conditions that cause stress and suppress natural behavior, while their collection from the wild depletes populations of a Critically Endangered species. Each farmed eel represents both an individual welfare concern and a contribution to a conservation emergency. The two issues are inseparable in this case, and neither can be addressed without addressing the other.

What You Can Do

Avoid consuming European eel products given the conservation emergency of this species
Support campaigns for stronger glass eel collection regulations to protect natural recruitment
Advocate for aquaculture certification schemes to refuse European eel certification given conservation status
Back research into eel breeding in captivity as the long-term solution to wild collection dependency
Choose sustainably sourced alternatives to eel in both restaurants and retail
