Pangasius Aquaculture and Welfare Standards

Pangasius catfish from Vietnam is among the world's most traded fish, but welfare and environmental standards in production have historically been inconsistent.

Key Facts

Vietnam produces over 1 million tonnes of pangasius annually, primarily for export to Europe and the US
Pangasius can tolerate low dissolved oxygen through air breathing, allowing high stocking densities
Water quality concerns in the Mekong Delta where most production occurs affect both fish welfare and food safety
ASC (Aquaculture Stewardship Council) certified pangasius production has grown but remains a minority share

Welfare Considerations

The ability of pangasius to survive in poor water conditions has been exploited by producers maintaining extreme stocking densities. Even if mortality is low, chronically stressed fish in poor water quality experience ongoing physiological distress. Certified production under ASC standards requires improved water quality, stocking density limits, and responsible antibiotic use. Consumer demand for certified products provides the market signal that incentivizes producers to invest in better welfare and environmental practices.

What You Can Do

Choose ASC-certified pangasius products and check for the certification logo when purchasing
Ask retailers about their pangasius sourcing standards if certification is not displayed
Support organizations advocating for mandatory welfare standards in pangasius exporting countries
Reduce consumption of uncertified pangasius products sourced without welfare documentation
