Aquaculture

Farmed Catfish Water Quality Welfare

Water quality in catfish aquaculture directly determines welfare outcomes, with poor water causing chronic stress and disease.

Key Facts

Catfish are sensitive to dissolved oxygen levels below 5 mg/L
Ammonia accumulation in high-density systems causes gill damage and distress
Recirculating aquaculture systems enable precise water quality control
High-stocking density catfish farming produces poor water quality conditions

Welfare Considerations

Catfish chronically exposed to poor water quality experience gill irritation, hypoxia, and immune suppression. The inability to escape to better water is a key distinction from wild conditions. Water quality management is the single most impactful welfare intervention in catfish farming.
