European eel farming raises urgent intersecting concerns about welfare, sustainability, and the conservation of a species now classified as critically endangered.
European eel presents a welfare and conservation crisis with no satisfactory resolution within current aquaculture models. Because eels cannot complete their reproductive cycle in captivity, farming requires continuous extraction of wild juveniles from an already critically depleted population. This creates an irreconcilable tension between farming demand and conservation necessity. The welfare of individual eels in farming systems — including slaughter practices — adds a further dimension to an already untenable situation. The ethical response is to cease eel farming until wild populations recover and until production systems exist that do not require wild stock extraction.
