Aquaculture

Welfare of Commercially Farmed Eel Larvae

European eel aquaculture depends entirely on wild-caught glass eels as no captive breeding cycle exists; larval welfare and wild capture impacts are significant concerns.

Key Facts

No one has ever bred European eels in captivity through a complete life cycle
All farmed European eels start as wild-caught glass eels from estuaries
Glass eel capture removes juveniles from critically depleted wild populations
Farming glass eels in intensive systems causes high early mortality from stress
Alternative eel species with established captive breeding may reduce wild capture pressure

Welfare Considerations

European eel aquaculture creates a direct pipeline from critically endangered wild populations into farming systems. The welfare harm of intensive early farming combines with the conservation harm of removing juveniles from populations that cannot sustain the pressure.

What You Can Do

Avoid European eel products given severe conservation and welfare concerns
Support research into complete-cycle eel aquaculture that would end wild glass eel capture
Advocate for glass eel quota reductions given population collapse
Choose alternative seafood that does not depend on critically endangered wild populations
