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.
