Welfare of Farmed Barramundi

Barramundi are a premium Australian and Asian aquaculture species; their welfare in sea cages and recirculating systems requires management of their aggressive, predatory nature.

Key Facts

They are aggressive predators requiring careful density management
Sea cage farming is common in Australia and Southeast Asia
Recirculating systems are used in cold-climate markets like the US
Barramundi show complex behavioral responses to crowding and poor conditions

Welfare Considerations

Barramundi welfare depends on managing their predatory aggression through appropriate stocking density and environmental enrichment. Their size range variation in a cohort means larger individuals bully smaller ones, requiring size grading to prevent injury welfare harms.
