My research over the past 25 years has been focused on different aspects of marine crustacean husbandry and management with an emphasis on crustacean reproduction in relation to seed production and farming systems. My work has focussed on seed production of penaeid shrimps Penaeus monodon, P. indicus and mud crabs Scylla spp., their reproductive physiology and production systems. I have standardised and developed hatchery production of mud crab species and developed a model for land based and open water integrated multi-trophic aquaculture systems. I have been principal and co-investigator for many projects related to these disciplines.
My research interests include nutrition and immunology of freshwater prawns. I have fifteen years’ research experience in aquaculture and feed formation, selection of new feed materials, fishmeal and fish oil replacement and feed management of Penaeus vannamei, crayfish Procambarus clarkii, and the freshwater prawns Macrobrachium rosenbergii and M. nipponensis in China. I am currently exploring use of transcriptomics, metabolomics and proteomics to understand nutrient needs, metabolism, stress and immunity and use of ingredients from diets and regulation of Chinese herbs.
