European and American eels are critically endangered, yet farmed eel production depends entirely on wild-caught juveniles. Their welfare and conservation are inseparably linked.
Eel farming sits at the intersection of serious welfare and conservation concerns. High-density recirculating systems cause crowding stress, skin damage from abrasion, and disease outbreaks. As fish with well-developed pain responses, eels experience these harms as genuine suffering. Harvest typically involves live chilling or gutting without prior stunning — prolonged and distressing processes. The conservation dimension is equally serious: every eel farm depends on extracting wild juveniles from populations already at critical collapse levels. Reducing eel consumption directly reduces both welfare harm and extinction pressure. Sustainable eel farming is essentially a contradiction in terms until captive breeding is achieved.
