My research interests include the captive breeding and larval rearing of brackishwater finfish species. I have ten years’ research experience in brackishwater finfish broodstock management, captive maturation, reproduction and larval rearing. I have been associated with captive seed production and aquaculture projects of our institute relating to economically important brackishwater finfish species such as pearlspot, grey mullet, Asian seabass and milkfish.


  • Evaluation of reproductive biology, breeding, larval biology and seed production of candidate finfish species for brackishwater aquaculture development.
  • Application of improved techniques for captive maturation, assessment of reproductive biology, system development for induced breeding, larval rearing and seed production of brackishwater candidate finfish species (ongoing).
  • Development and refinement of finfish culture technologies for sustainable brackishwater aquaculture development.
  • Development and evaluation of novel culture technologies for candidate brackishwater finfishes for sustainable aquaculture (ongoing).
