Advanced catfish aquaculture using recirculating systems with precise environmental control offers significant welfare improvements over pond-based production through better oxygen management and reduced disease pressure.
Recirculating aquaculture systems represent a genuine welfare advance for catfish by eliminating the unpredictable oxygen crashes and disease pressures of conventional pond production. The controlled environment allows welfare monitoring through water quality parameters that serve as early warning indicators of impending welfare compromise. The higher capital and energy costs create economic barriers to adoption, but where recirculating systems are used, catfish welfare outcomes are measurably better than pond alternatives. Investment in recirculating aquaculture is therefore a high-leverage welfare intervention for the catfish industry.
