Farmed Catfish Welfare in US Aquaculture

Channel catfish is the most important farmed fish in the United States. Welfare considerations in this sector have received less attention than in other aquaculture species.

Key Facts

US catfish aquaculture produces approximately 250,000 tonnes annually, primarily in Mississippi, Alabama, and Arkansas
Catfish are bottom-dwelling omnivores with sensory barbels used for food detection in murky water
Crowding stress in catfish ponds leads to elevated cortisol, aggression, and increased disease susceptibility
Oxygen depletion is a significant welfare emergency in catfish ponds during hot summer nights when algal respiration depletes dissolved oxygen
Aeration systems that prevent oxygen crashes save both welfare and production, creating clear alignment of interests
Slaughter practices for catfish vary from electrical stunning to live CO2 exposure with varying welfare implications

Welfare Considerations

Catfish welfare in US aquaculture represents a significant but understudied area of farm animal welfare. With hundreds of millions of catfish produced annually, even small improvements in welfare-critical parameters like oxygen management, stocking density, and slaughter methods could reduce enormous amounts of suffering. The challenge is that catfish welfare science lags behind mammalian research, and industry attention to welfare is limited. Building the evidence base and connecting welfare outcomes to production outcomes is the most effective route to improvement.
