Pangasius Catfish Welfare in Aquaculture

Pangasius catfish from Vietnam and Southeast Asia represent one of the largest volume farmed fish species globally. Welfare standards in this high-volume industry require attention.

Key Facts

Vietnam produces over 1.3 million tonnes of pangasius annually, primarily for export
Pangasius (basa or swai) is one of the most traded fish species globally by volume
They are farmed at very high densities in river cages and ponds in the Mekong Delta
Pangasius are resilient, tolerating low oxygen levels that would kill many other fish
Processing involves live transport over long distances and often minimal stunning
Certification schemes exist but welfare provisions vary significantly between farms

Welfare Considerations

Pangasius welfare challenges stem primarily from extreme stocking densities, water quality management, transport stress, and slaughter practices. High production volumes drive cost-cutting that can compromise welfare. Fish transported alive may experience prolonged stress before slaughter. Stunning before killing is not universal. Disease management in high-density systems relies heavily on antibiotics, creating additional welfare and food safety concerns. Improving pangasius welfare requires density limits, water quality monitoring, stunning requirements, and stronger enforcement of certification standards.

What You Can Do

Choose pangasius certified to welfare-conscious standards like ASC when available
Ask retailers about welfare and sustainability standards for pangasius they sell
Support regulations requiring stunning before slaughter for all farmed fish including pangasius
Reduce consumption of high-volume farmed fish species until better welfare is standard
