Farmed Catfish Welfare: US Aquaculture and Welfare Standards

Channel catfish are the most widely farmed fish in the United States, raised in earthen pond systems with welfare challenges around crowding, oxygen management, and slaughter.

Key Facts

US channel catfish aquaculture produces approximately 300,000 metric tons annually
Catfish are raised in large earthen ponds at stocking densities of 3,000-6,000 kg per hectare
Low dissolved oxygen is the primary acute welfare and mortality risk in catfish pond systems
Catfish are slaughtered using a variety of methods including live chilling and CO2, few of which are optimal
Catfish have taste buds distributed across their body surface and barbels for environmental sensing

Welfare Considerations

Catfish welfare in US aquaculture is shaped primarily by the earthen pond production system, which provides more naturalistic conditions than tank or cage systems but still creates welfare risks from crowding and oxygen depletion. Improved aeration management, lower stocking densities, and transitioning to electrical or percussive stunning before slaughter represent achievable welfare improvements. The US catfish industry currently lacks the welfare certification frameworks present in European aquaculture.

What You Can Do

Support development of US aquaculture welfare certification standards that include catfish
Advocate for mandatory stunning before slaughter in US commercial catfish operations
Choose catfish from producers using lower stocking densities and documented welfare protocols
