Pangasius Catfish Welfare in Advanced Aquaculture

Pangasius (striped catfish) is one of the most farmed fish species globally, yet welfare standards in its production remain poorly developed.

Key Facts

Vietnam produces over 1 million tonnes of pangasius annually, making it a globally significant aquaculture species
Pangasius can tolerate low oxygen levels but this adaptation is exploited through extreme stocking densities
Crowding stress in pangasius leads to elevated cortisol, fin damage, and increased disease susceptibility
Pangasius have sensitive barbels (whisker-like organs) that can be damaged in high-density culture
Harvest mortality from poor slaughter practices is a major welfare concern in pangasius production
GlobalG.A.P. and ASC certification schemes are beginning to incorporate basic pangasius welfare metrics
Pangasius are social fish that show reduced stress in stable social groups

Welfare Considerations

Pangasius welfare is largely shaped by extreme economic pressure to minimize production costs. High stocking densities create chronic crowding stress that impairs immune function and promotes disease outbreaks, often treated with antibiotics rather than improved husbandry. Slaughter practices vary widely, with many facilities lacking effective stunning equipment. Certification schemes offer a pathway to improvement, but consumer awareness of pangasius welfare remains low. Improving welfare in pangasius production requires both regulatory action in Vietnam and consumer pressure through certification requirements in importing countries.

What You Can Do
