Advanced welfare science for pangasius aquaculture, covering behavioral welfare indicators, new research on pangasius cognition, and the development of improved welfare standards for this widely traded fish.
Advanced pangasius welfare science is building the evidence base needed to transform certification standards from environmental-only frameworks to genuinely welfare-inclusive systems. The air-breathing capability of pangasius means they tolerate low dissolved oxygen — but tolerance does not indicate absence of welfare harm at suboptimal oxygen levels. Behavioral welfare indicators including fin damage assessment and activity pattern monitoring are being applied to pangasius production to supplement the physiological measures used for salmonids. Slaughter welfare research provides technical foundations for implementing electrical stunning at commercial scale — a welfare improvement that would benefit billions of fish annually if adopted. The trajectory of pangasius welfare science is promising, but translation into industry practice requires market incentives that consumer choices and retailer standards can provide.
