Pangasius Catfish Welfare: Global Trade and Vietnamese Aquaculture

Pangasius catfish from Vietnamese river ponds is one of the most widely traded fish globally. Its rapid expansion has created welfare concerns about stocking densities and slaughter practices.

Key Facts

Vietnam exports over 1.5 million tonnes of pangasius annually, making it one of the largest fish export industries
Pangasius are highly tolerant of crowding and low oxygen — making intensive production economically attractive
Stocking densities in some pangasius ponds are among the highest of any farmed fish globally
Pangasius are typically processed while alive — slaughter methods are not standardised for humaneness
The Aquaculture Stewardship Council certifies some pangasius producers against welfare and environmental standards

Welfare Considerations

Pangasius welfare in intensive Vietnamese aquaculture involves extremely high stocking densities, high levels of parasite and disease pressure from crowding, and slaughter methods that may not achieve rapid loss of consciousness. Their physiological tolerance of crowding does not mean they are unaffected by it — chronic stress from high density impairs immune function and behaviour. Certification schemes exist but cover a minority of production. Consumer pressure for certified sustainable and welfare-conscious pangasius can drive improvement.

What You Can Do

Look for Aquaculture Stewardship Council certification on pangasius products
Ask supermarkets and fish retailers about welfare standards for pangasius in their supply chain
Support Vietnamese aquaculture reform through FAO and international development partnerships
Reduce overall farmed fish consumption or diversify toward species with lower-intensity production requirements
