Professor Paul Southgate

Professor

BSc. Portsmouth, UK., MSc. Heriott-Watt, UK., PhD James Cook University.

Member of the: World Aquaculture Society, ICLARM Network of Tropical Aquaculture Scientists, National Shellfisheries Association (USA), International Development Research Centre Mollusc Culture Network.

Research interests

  • Tropical aquaculture

  • Biology and culture of pearl oysters

  • Nutrition of cultured aquatic animals – particularly larval stages

  • Development of formulated foods for larval stages

  • Hatchery production of fish and shellfish

  • Aquaculture and development of coastal communities

  • Molluscan taxonomy

Recent and Current Projects Include

My primary research focus is the biology and culture of pearl oysters. Much of my research in this field has been conducted collaboratively with Pacific island nations (Kiribati, Fiji, Solomon Islands, and Tonga) as part of a major international project funded by the Australian Centre for International Agricultural Research (www.aciar.gov.au). I have on-going research with pearl oysters in Mexico and China, and in Tanzania where I collaborate with World Wide Fund for Nature (WWF) to determine the potential for pearl production as a means of income generation for communities within marine protected areas. Research with government departments and industry partners within Australia has focused on industry diversification through the use of “non-traditional” pearl producing species. A second major research focus is nutrition of the larval stages of marine organisms used in aquaculture and the development of formulated diets for them.

Recent and Currently Supervised Projects

.

  • Broodstock management and egg quality of pearl oysters.

  • Spatio-temporal factors effecting growth of cultured pearl oysters.

  • Factors influencing pearl quality.

  • Quantitative and qualitative aspects of the protein nutrition of barramundi (Lates calcarifer) larvae fed formulated foods.

  • Development of formulated diet for larvae and juveniles of crabs.

Future PhD Directions

  • Nutritional requirements of the larvae of crabs and other tropical crustaceans.

  • Culture of pearl oysters and factors influencing pearl quality.

  • Developing formulated foods for cultured invertebrate larvae.

  • Income generation from aquaculture for coastal communities in developing countries.

  • Development of marine invertebrate aquaculture in the Pacific islands and east Africa.
