Pangasius Aquaculture Welfare: Vietnam's Most Exported Fish

Pangasius catfish from Vietnam is one of the world's most widely exported farmed fish species, with welfare standards lagging behind production scale.

Key Facts

Vietnam exports over 1.5 million tonnes of pangasius annually, primarily to Europe, the US, and Asia
Stocking densities in pangasius ponds can reach 300-500 fish per cubic meter in intensive systems
Water quality including dissolved oxygen and ammonia is the primary welfare determinant in pangasius production
ASC pangasius certification exists but uptake among Vietnamese producers has been slower than in other species
Pangasius are obligate air breathers and require surface access — overcrowding restricts this behavior

Welfare Considerations

Pangasius welfare is challenged by the extreme stocking densities used in intensive Vietnamese pond culture. As obligate air breathers, pangasius must access the water surface regularly — overcrowding interferes with this essential behavior, causing chronic physiological stress. Welfare improvements require density reduction, water quality management including oxygenation, and harvest practices that minimize crowding duration. The scale of global pangasius trade means market-driven welfare improvements through certification uptake or buyer requirements have significant aggregate welfare impact.

What You Can Do

Choose ASC-certified pangasius products where available
Engage retailers about their pangasius supplier welfare requirements
Support development of welfare criteria specifically addressing pangasius density and water quality
Reduce pangasius consumption or choose alternative species with stronger welfare certification systems
Advocate for pangasius-specific welfare provisions in aquaculture import regulations
