Farmed Catfish Welfare: Pond and Intensive Production Systems

Channel catfish and pangasius are among the most farmed fish globally. Their welfare needs relate to water quality, crowding, and humane slaughter practices.

Key Facts

Channel catfish and pangasius (striped catfish) together account for millions of tonnes of annual production
Catfish are social fish that form groups and show stress responses when isolated
Pond-based catfish systems can develop poor water quality especially in hot weather, causing hypoxia
Electrical stunning before slaughter is effective for catfish when applied at appropriate parameters
Catfish have nociceptors and respond to noxious stimuli similarly to other teleost fish

Welfare Considerations

Catfish welfare concerns centre on water quality management, crowding, and slaughter practices. In pond systems, algal blooms and temperature stratification can cause dangerous oxygen depletion, leading to mass mortality events. Intensive recirculating systems maintain better water quality but require careful management. During harvest, crowding and air exposure cause acute stress. Electrical stunning before slaughter is welfare-positive but requires species-specific parameters. The growing catfish industry is beginning to adopt welfare standards as consumer awareness increases.

What You Can Do

Choose catfish from producers with water quality monitoring and welfare standards
Support aquaculture certification programmes that include welfare criteria
Advocate for humane slaughter requirements in catfish processing
Reduce consumption of catfish unless from certified responsible sources
