Pangasius Catfish Welfare in Vietnam's Mekong Delta Aquaculture (2026)

Vietnam produces over 1.5 million tonnes of pangasius catfish annually in Mekong Delta ponds, with welfare concerns around extreme stocking densities, water quality, and slaughter practices.

Key Facts

Vietnam is the world's largest producer of pangasius (Pangasianodon hypophthalmus), exporting to over 140 countries
Stocking densities in pangasius ponds can reach 60-80 kg/m3 — among the highest of any farmed fish
Pangasius are air-breathing catfish tolerant of low oxygen, which facilitates extreme crowding
Most pangasius are killed by live bleeding without prior stunning at processing facilities

Welfare Considerations

Despite pangasius tolerance of hypoxic conditions, extreme stocking densities cause chronic stress, immune suppression, and elevated disease susceptibility. Fin erosion and skin damage from abrasion are common in crowded ponds. Rapid pond draining before harvest concentrates fish in declining water quality, causing panic responses and physical injury. Live bleed slaughter without stunning causes prolonged suffering. Antibiotic use for disease management generates resistance concerns and likely indicates ongoing health failures.

What You Can Do

Choose pangasius certified by ASC (Aquaculture Stewardship Council) which requires welfare assessments
Advocate for mandatory pre-slaughter stunning in Vietnamese aquaculture export standards
Support welfare science development for pangasius and other high-volume farmed species
Raise awareness of welfare conditions in pangasius production through consumer education
