Farmed Catfish Welfare in US Aquaculture

Welfare considerations for channel catfish, the most farmed finfish in the United States.

Key Facts

Channel catfish is the most farmed finfish in the US, with production centered in the Mississippi Delta
Catfish farming typically occurs in earthen ponds with variable water quality depending on seasonal conditions
Catfish are air-breathing vertebrates that experience hypoxia stress when dissolved oxygen levels drop
Pond oxygen management through mechanical aeration is essential for catfish welfare and survival
Catfish slaughter typically involves electrical stunning followed by mechanical killing in modern facilities
Catfish are benthic species that prefer structured habitats with shelter and varied substrate

Welfare Considerations

Catfish welfare receives relatively little attention compared to salmon despite being the most farmed finfish in the US. Welfare challenges include dissolved oxygen management in pond systems where warm temperatures and algae blooms can cause hypoxia events with mass mortality, crowding stress during harvest, and the welfare of the slaughter process. US catfish production has adopted electrical stunning before slaughter more widely than many global producers, but welfare standards for pond management and handling during harvest continue to need improvement. Species-specific welfare standards for catfish would drive the most meaningful improvements.

What You Can Do

Choose catfish from certified operations with documented water quality management standards
Support regulatory development of catfish-specific welfare standards in US aquaculture
Advocate for oxygen management requirements in pond aquaculture regulations
Support research into catfish behavioral welfare needs and appropriate housing standards
