Aquatic Welfare

Catfish Aquaculture Welfare Standards

Channel catfish and pangasius are among the most farmed fish species globally, yet welfare standards in production remain underdeveloped.

Key Facts

Channel catfish production in the US exceeds 300 million pounds annually
Pangasius (basa) is among the most consumed fish globally
High stocking densities cause increased aggression and injury
Catfish are sensitive to water quality and respond to pain stimuli
Slaughter methods vary widely with minimal welfare oversight

Welfare Considerations

Catfish show clear nociceptive responses and behavioral indicators of distress under poor conditions. Overcrowding leads to fin and barbel damage. Many facilities use CO2 stunning or ice slurry methods that are slow and potentially painful. Improving stocking density limits and adopting electrical or percussive stunning can meaningfully reduce suffering.

What You Can Do

Choose catfish products certified under welfare-conscious aquaculture schemes
Advocate for mandatory stunning before slaughter in aquaculture regulations
Support research into catfish pain and stress physiology
Encourage retailers to require welfare audits from suppliers
