Channel Catfish Welfare in North American Aquaculture

Welfare science for the United States most widely farmed freshwater fish species.

Key Facts

Channel catfish is the primary farmed fish in the United States — over 200,000 tonnes annually
Farmed in large earthen ponds in the Mississippi Delta region
They are omnivorous and tolerant but suffer welfare compromise in high density
Electrofishing harvest methods raise welfare concerns — electrical stunning effects are poorly characterised

Welfare Considerations

Channel catfish welfare in intensive pond culture is affected by crowding, oxygen depletion in hot summer months, and handling during harvest. Pond aeration management is critical for summer welfare. Harvest welfare is an area of active research — current methods involving crowding and electrofishing cause significant stress. Welfare certification for US catfish is developing but remains limited compared to salmon.
