Pangasius Welfare in Aquaculture: Addressing a Global Species

Pangasius (Pangasianodon hypophthalmus) is among the world's most farmed fish, with welfare standards lagging behind production scale.

Key Facts

Pangasius production exceeds 2 million tonnes annually, primarily in Vietnam
High stocking densities in ponds can reach 80-100 kg/m3 in intensive systems
Pangasius tolerate low oxygen levels but suffer reduced welfare at chronic hypoxia
Streptococcal disease and hemorrhagic disease are significant welfare concerns
Processing practices including live transport and crowding before slaughter cause acute stress
ASC certification has been sought by some producers but welfare criteria remain limited
The global price competitiveness of pangasius drives race-to-bottom production conditions

Welfare Considerations

Pangasius aquaculture represents a massive welfare challenge at scale - billions of fish in conditions that prioritize cost efficiency over animal welfare. High densities, water quality challenges, and poor slaughter practices create chronic and acute welfare problems that are rarely addressed by existing certification schemes. Improving welfare in pangasius production requires both consumer pressure for better standards and investment in production practices that are welfare-compatible with the species' biology and behavioral needs.

What You Can Do

Ask retailers about pangasius sourcing and what welfare standards are required of suppliers
Support certification schemes that are strengthening pangasius welfare requirements
Choose alternative white fish species from lower-intensity production systems where available
Reduce consumption of low-welfare certified pangasius while advocating for better standards
Engage with seafood certification bodies to develop meaningful pangasius welfare criteria
