Channel catfish farming in the US is one of the largest aquaculture sectors, and recent research is improving welfare through better handling and water quality management.
Catfish welfare in aquaculture has historically received less attention than salmon or trout, but they are intelligent, social fish capable of experiencing pain and stress. Key welfare concerns include hypoxia from overcrowding, rough handling during harvesting, and slaughter methods that may not ensure unconsciousness before death. Progress in aeration, monitoring technology, and stunning methods is improving conditions, though comprehensive welfare standards for catfish aquaculture are still developing.
