Farmed Pangasius Advanced Welfare Standards

Advanced welfare standards for farmed pangasius address the specific needs of this widely-traded catfish species and the particular challenges of its intensive production systems.

Key Facts

Pangasius (Vietnamese catfish) is one of the most globally traded fish species with production exceeding 1.5 million tonnes annually
Pangasius are air-breathing fish tolerant of low oxygen but this tolerance is not infinite
Intensive pangasius farming in the Mekong Delta faces water quality and disease challenges
Certification schemes including ASC have developed standards for pangasius production
Crowding during harvest and transport is a major welfare concern in pangasius production
Pangasius show stress responses including elevated cortisol during handling and crowding

Welfare Considerations

Advanced pangasius welfare standards must address the full production cycle from fingerling rearing through grow-out to slaughter. While pangasius tolerance of variable oxygen conditions reflects their natural ecology, optimal welfare requires water quality management well above survival thresholds. Harvest practices including dewatering ponds and crowding fish before capture create acute stress that welfare-forward operations minimize through optimized protocols. Transport welfare requires attention to density, water quality and handling minimization. Pre-slaughter stunning validation for pangasius species is needed to ensure humane killing methods are effective for this species.
