Pangasius, also called basa or tra, is among the world most traded fish, and improving welfare standards in Vietnamese aquaculture is increasingly important for the global seafood market.
Pangasius aquaculture operates at a scale that makes it one of the most welfare-significant fish species in global production. The extremely high stocking densities typical in Vietnamese river cage farming create chronic crowding stress, elevated disease pressure, and poor water quality that compromises welfare throughout the production cycle. Certification schemes have driven improvement in larger, export-oriented operations, but the majority of pangasius farms remain unaudited. The welfare evidence base for pangasius is less developed than for salmon or trout, but their neurological complexity as teleost fish with functional nociceptors supports welfare consideration. Consumer preference for certified products and retailer commitments to responsible sourcing are the most powerful drivers of welfare improvement in this sector.
