Eel farming is a growing industry with significant welfare concerns, as eels have complex physiological and behavioral needs that commercial systems often fail to meet.
Eel welfare sits at the intersection of sentience uncertainty, conservation concern, and commercial pressure. The scientific evidence for eel nociception and stress responses is substantial - they clearly respond to noxious stimuli and show behavioral and physiological signs of chronic stress in commercial systems. The conservation crisis for wild eel populations adds another dimension: the trade in wild-caught glass eels for farming is contributing to the collapse of the species while creating significant welfare problems. Both conservation and welfare concerns argue for urgent reform of the eel farming industry.
