Barramundi is an increasingly popular farmed fish species globally. As production expands, ensuring welfare standards are embedded in farming practices becomes increasingly important.
Barramundi welfare concerns include stocking density, water quality management, handling stress, and slaughter methods. High densities cause competition, aggression, and chronic cortisol elevation. Barramundi are sensitive to poor water quality, and welfare declines rapidly when oxygen levels drop. Slaughter practices vary widely and often do not include prior stunning, causing unnecessary suffering. Recirculating aquaculture systems (RAS) can maintain better water quality but may have other welfare tradeoffs. Welfare-conscious operators monitor behavioral indicators and maintain optimal stocking densities.
