Pangasius (also called basa or swai) is one of the world's most popular farmed fish. Farmed primarily in Vietnam's Mekong Delta, welfare conditions vary widely across the industry.
Pangasius aquaculture, while economically important for Vietnamese farming communities, presents significant fish welfare challenges. High stocking densities, even within certified systems, may exceed fish welfare thresholds. Fish at these densities show increased aggression, stress responses, and fin damage. Harvest methods typically involve crowding, air exposure, and killing without stunning — practices increasingly inconsistent with evolving understanding of fish sentience. Consumer demand for pangasius continues to grow due to its mild flavor and low price, making welfare improvement through supply chain standards and certification increasingly urgent. Traceability and clear labeling would help welfare-conscious consumers make informed choices.
