The United States is a major producer of channel catfish in the Mississippi Delta region. Intensive pond-based production creates significant welfare challenges including overcrowding, disease outbreaks, and slaughter methods.
Channel catfish are vertebrates with well-demonstrated pain responses including avoidance learning and protective behaviours. Harvest by electric shock followed by crowding and dip netting causes acute stress and physical injury. Processing without pre-stunning causes prolonged suffering. The economic pressure of competition from lower-cost Asian imports creates incentives to reduce welfare-positive infrastructure investment.
