Catfish pond farming welfare depends on water quality, stocking density, and disease management; improvements reduce suffering at scale.
Farmed catfish welfare is determined primarily by water quality management, stocking density, and disease prevention. Overcrowded ponds with poor water quality cause chronic stress, disease susceptibility, and oxygen-deprivation episodes that cause acute suffering. Progressive catfish producers monitor dissolved oxygen continuously and use aeration to prevent welfare-critical hypoxia events.
