Improving feed sustainability for marine aquaculture in Vietnam and Australia

Three previous ACIAR projects have focused on nutrition of important aquaculture species. This new project will profit from the results of the earlier projects and combine research efforts into the main issue in common - the reliance on low-value fish as the main feed source for aquaculture. This new project will study issues related to diet development and low-value fish replacement, and bring together a collective of important aquaculture sectors in Vietnam. The key subjects for study will be finfish (barramundi/Asian seabass, grouper and cobia), mud crabs and spiny lobster. The research team will seek to identify the extent of feed ingredient resource risks and the barriers (perceived and real) to adoption of manufactured feed by marine aquaculture sectors. Understanding the risks (scientific, social, economic and environmental) will give the team a platform for developing strategies to address them - ideally leading to greater adoption of manufactured feed in Vietnam and improved use of alternative raw materials in both Vietnam and Australia. Having one collective project will ensure maximisation of resource-sharing and knowledge transfer among both the Vietnamese and Australian collaborators.
