Barramundi (Asian seabass) is farmed widely across Asia, Australia and increasingly the USA, with welfare challenges related to temperature tolerance and aggression.
Barramundi welfare varies significantly by production system. Pond-based systems in tropical Asia often involve high stocking densities with variable water quality. Recirculating systems in temperate countries maintain optimal temperature and water quality but require intensive management. Aggression during feeding causes injuries that compromise welfare and predispose to infection. The development of welfare standards appropriate to the diversity of barramundi production systems globally requires coordinated research and stakeholder engagement.
