Research areas

  • Tropical aquaculture
  • Biology and culture of pearl oysters and other marine invertebrates
  • Nutrition of cultured aquatic animals
  • Larval development and energetics (marine invertebrates)
  • Developing aquaculture-based livelihoods
  • Molluscan taxonomy and palaeontology


Professor Southgate’s research focuses on tropical aquaculture with particular emphasis on pearl oysters and other molluscs, marine invertebrates and marine ornamental species. Development of sustainable tropical aquaculture industries and aquaculture-based livelihood opportunities in coastal communities, are among his major research interests. Professor Southgate has active research projects in many Pacific island and south-east Asian countries, and in east Africa and Central America, and many of his research student’s work in partner countries. Professor Southgate co-edited and co-authored the best-selling undergraduate textbook for Aquaculture (Lucas & Southgate, 'Aquaculture: Farming Aquatic Animals and Plants') and the first monograph on the biology and culture of pearl oysters (Southgate & Lucas, 'The Pearl Oyster'). He joined USC in January 2015.
