Channel catfish farming in the US southeastern states is a major aquaculture industry. Understanding welfare challenges and ongoing improvements in this sector helps consumers make informed choices.
US catfish farming welfare involves both chronic production stressors and acute harvest challenges. In earthen ponds, water quality management is critical — dissolved oxygen crashes in summer or winter cause mass mortality events where fish experience hypoxia and possible suffocation over extended periods. These events affect hundreds of thousands to millions of fish and represent significant welfare harm despite occurring naturally in some contexts. Catfish behavior in ponds is poorly characterized but includes schooling, territorial behavior, and foraging exploration that high-density monoculture systems may restrict. At harvest, seine netting is stressful but is followed by electrical stunning in most US processing facilities — a relatively positive aspect of the industry compared to many global equivalents. Improvements in water quality monitoring, aeration technology, and harvest handling would advance welfare outcomes in this established US industry.
