Aquaculture is the world’s fastest-growing food-producing sector and the fastest-growing primary industry sector in the Indo-Pacific. It is also recognised as part of the solution to regional food security.
USC’s Tropical Aquaculture research team combines science, economics and social science to develop industries and programs that are profitable, sustainable and culturally appropriate.
A key aspect is institutional capacity building in partner agencies, thus supporting long-term development.
Led by Professor of Tropical Aquaculture, Paul Southgate, our team of internationally recognised experts is currently working on a number of major research projects with over $15 million of external funding.
