Channel catfish aquaculture is the largest US aquaculture sector and operates under relatively weak welfare standards.
Channel catfish aquaculture operates with minimal welfare infrastructure despite its economic scale. The earthen pond system creates inherent challenges for water quality management, and the consequences of failures are borne by fish through mass mortality or chronic hypoxic stress. Harvest welfare is particularly inconsistent — crowding, hauling, and processing without adequate stunning remain common. Consumer awareness of US catfish welfare is low, limiting market-based pressure for improvement. Regulatory development of welfare standards for catfish — including minimum water quality parameters and mandatory stunning at slaughter — would provide welfare benefits at scale.
