Channel catfish are the most commonly farmed fish in the United States, with welfare concerns centered on stocking density, water quality management, slaughter methods, and the behavioral and physiological needs of a species adapted to complex freshwater environments.
Catfish welfare in US aquaculture is an area with significant room for improvement. The absence of mandatory stunning requirements means many catfish enter slaughter without effective insensibility — a welfare failure that would not be acceptable for any vertebrate in a meat processing plant. Their hardiness, which makes them relatively easy to farm, may paradoxically reduce welfare attention because they can survive conditions that cause significant stress. As the most commonly consumed farmed fish in the US, even modest improvements in catfish welfare standards — including mandatory stunning requirements and stocking density limits — would affect tens of millions of animals annually.
