Farmed Eel Welfare and Slaughter

European and Japanese eel farming raises distinct welfare concerns due to the species extraordinary biology, sensitivity, and the methods used for slaughter.

Key Facts

European eel populations have declined by over 90% since the 1970s, making wild eel capture for farming controversial
Farmed eels are typically slaughtered by immersion in ice water or salt, which is a prolonged and stressful process
Eels have a highly developed nervous system and show pain responses to noxious stimuli
Japanese eel farming consumes vast quantities of wild-caught juvenile eels, depleting natural populations
Electrical stunning before slaughter significantly reduces eel suffering but is not universally adopted

Welfare Considerations

Eel welfare at slaughter is particularly poor. Common slaughter methods including immersion in ice slurry or salt cause prolonged distress before loss of consciousness — eels may remain conscious and responsive for extended periods during these procedures. The welfare case for electrical stunning before slaughter is strong and the technology is available. Beyond slaughter, the farming of European and Japanese eels relies on wild-caught juveniles from depleted wild populations, creating a conservation welfare crisis that underpins the production system. Certified welfare-positive eel products are extremely rare.

What You Can Do

Reduce or eliminate eel consumption given the difficulty of sourcing welfare-positive products
If purchasing eel, ask suppliers about slaughter methods and prioritise electrically stunned products
Support campaigns for mandatory humane slaughter standards for eel farming
Oppose the international trade in wild-caught eel juveniles that depletes endangered wild populations
