Catfish Welfare in Aquaculture | Animal Welfare Hub

Welfare considerations in the farming of channel catfish and other catfish species globally.

Key Facts

Channel catfish is the dominant aquaculture species in the United States, farmed across the southeastern states
Pangasius catfish from Southeast Asia is among the most globally traded farmed fish
Catfish are omnivorous bottom-dwellers with specific environmental needs including appropriate substrate and cover
High stocking densities in catfish ponds can cause oxygen depletion and chronic stress
Catfish are sensitive to handling and transport, with significant cortisol elevation during these events
Disease management including columnaris and ESC in US catfish farming has welfare implications for affected fish

Welfare Considerations

Catfish welfare in aquaculture receives relatively little attention compared to salmonids, yet they are farmed at significant scale globally. Their bottom-dwelling, low-light preferences are difficult to accommodate in standard pond and tank systems, and the welfare implications of dense stocking in featureless environments are not well characterized. What is clear is that catfish experience stress responses to handling and transport, and that disease events cause significant welfare harm. Improving welfare in catfish farming requires better understanding of their behavioral needs and development of species-specific husbandry standards.

What You Can Do

Support aquaculture research that examines catfish behavioral needs and welfare indicators
Choose farmed catfish from certified operations with documented health and water quality management
Advocate for catfish-specific welfare criteria within aquaculture certification schemes
Raise awareness that catfish farming welfare deserves the same attention as higher-profile species
Engage with retailers about the welfare standards of their catfish suppliers
