Barramundi is a premium farmed fish across Asia Pacific with growing welfare research attention. Temperature management, crowding, and slaughter practices are key welfare issues.
Barramundi welfare research is less extensive than for salmonid species but is growing in proportion to the industry expansion. Their territorial and cannibalistic tendencies during juvenile stages require intensive size grading to reduce conspecific aggression — a repeated handling welfare cost. Optimal temperature management is critical for this warm-water species; thermal stress from sub-optimal temperatures causes immune suppression and chronic welfare compromise. Slaughter welfare for barramundi is variable across the industry — CO2 stunning and live chilling remain common despite their poor welfare outcomes, while percussion and electrical stunning represent best practice. The premium market positioning of Australian barramundi creates commercial incentives for welfare certification that are being explored through industry-NGO partnerships.
