Catfish aquaculture is a major industry in the US, Southeast Asia, and Africa, with welfare considerations centered on pond management, handling, and slaughter practices.
Catfish aquaculture welfare shares many features with other finfish welfare but has species-specific considerations. Channel catfish barbs can inflict wounds on handlers and on each other during crowding, creating both human safety and animal welfare concerns during harvest. Their documented nociceptive responses mean that harvest methods should minimize pain as much as other commercial fish species. Water quality management is particularly critical because catfish in oxygen-depleted or ammonia-elevated conditions show visible distress. The regulatory framework for catfish welfare is developing more slowly than salmon welfare standards, requiring consumer pressure and industry leadership to drive improvement.
