Overview: Welfare science for barramundi in intensive tropical aquaculture systems across Australia and Southeast Asia.
Key Welfare Facts
Barramundi is a highly valued species in Australian and Asian aquaculture, grown in ponds, cages, and RAS systems.
Territorial aggression and cannibalism of smaller conspecifics are significant welfare challenges in juvenile production.
Barramundi are euryhaline, tolerating fresh and saltwater, but rapid salinity changes cause osmotic stress.
Optimal temperature range is 26-30°C; temperatures outside this cause immunosuppression and behavioural change.
Disease challenges including vibriosis and viral nervous necrosis cause mass mortality and significant welfare compromise.
Slaughter welfare varies widely; electrical stunning before live-chilling is increasingly adopted in premium production.
Welfare Assessment
Barramundi welfare requires attention to size grading, density management, and water quality throughout the production cycle. Supporting certified production schemes encourages adoption of higher welfare practices throughout the industry.
