Research Interests

  • Aquaculture of local marine fish species: 'opakapaka (pink snapper Pristipomoides filamentosus), kahala (longfin yellowtail Seriola rivoliana), giant grouper (Epinephelus lanceolatus), 'ama'ama (striped mullet Mugil cephalus) and the freshwater tilapia (Oreochromis niloticus)
  • Fish nutritional requirements and feeding protocols
  • Use of Spirulina and other algal meals as ingredients in feeds for carnivorous fish
Feeding trial with mullet juveniles
