Farmed Catfish Welfare: High-Volume Production with Minimal Standards

Catfish is among the most widely farmed fish in the world, particularly in the US and Southeast Asia, with almost no species-specific welfare standards despite their clear capacity for stress.

Key Facts

Channel catfish aquaculture in the US produces approximately 300,000 tonnes annually from earthen pond systems
Pangasius (basa) catfish from Vietnam and neighboring countries is one of the most globally traded farmed fish
Catfish are hardy and disease-resistant compared to salmonids, but crowding stress still compromises welfare
Catfish have the ability to breathe air and tolerate low oxygen conditions that would stress most fish
Slaughter methods for catfish including scaling while alive are significant welfare concerns

Welfare Considerations

Catfish welfare occupies a peculiar position in aquaculture ethics: their physiological hardiness has been interpreted as reduced need for welfare consideration, when in reality it simply means they can survive conditions that other fish cannot. Survival under stress is not welfare — fish that are air-breathing and stress-tolerant still experience fear, crowding stress, and pain. Scaling live catfish, common in some markets, causes obvious suffering in fish whose hardiness allows them to survive the process longer. Welfare standards need to address catfish specifically rather than applying only to more commercially prestigious species.

What You Can Do

Choose catfish from producers with documented humane slaughter and welfare management
Advocate for catfish-specific welfare provisions in aquaculture regulation
Support research into catfish sentience and welfare needs
Reduce farmed catfish consumption or choose alternative protein sources
Ask retailers about their catfish sourcing country and welfare standards
