Welfare considerations for farmed eels including their unique biology, stress physiology and the ethical challenges of eel production.
Eel welfare sits at a troubling intersection of conservation and animal welfare concerns because the very existence of eel aquaculture depends on harvesting critically endangered wild populations of juvenile eels. The welfare problems within farms are compounded by the conservation harm of the industry itself, creating a situation where welfare improvements in farming do not address the fundamental problem of wild population depletion. Eels also present particular slaughter welfare challenges because their neurological resilience means that inhumane killing methods cause prolonged suffering. Consuming farmed eel therefore creates welfare and conservation harms that are difficult to mitigate through consumer choices within the current production system.
