Research Activity

There are many aquatic organisms that are difficult to raise under artificial condition. My major interest is to clarify how these organisms live, survive and adapt to aquatic ecosystem, which can be the basis of aquaculture. I use microsopic animals such as rotifers, cladoceran and copepods as model organisms (these are also diet for larval stage of aquatic animals).

By jointing with Prof. Yoshitaka Sakakura and laboratory students, Laboratory Aquaculture Biology, Nagasaki Univ. conducts studies as following.

I. Live food
  - Development of culture library (rotifer, cladoceran, copepod)
  - Genetic analysis and identification
  - Regulation of life cycle
  - Culturing and preservation (health check, stress resistence, biologically active substance, resting egg)

II. Larviculture
  - Larval health diagnosis
  - Optimal feeding regime
  - Rearing tank technology

We express our sincere gratitude to a number of research collaborators, including alumuni of our laboratory; Prof. Koushirou Suga (Lab. Fish Pathology, Nagsaki University), Assoc. Prof. Hee-jin Kim, Prof. Jae-Seong Lee (Sunkyunkwan Univ. Korea), Prof. Tomonari Kotani (Kagoshima Univ.), Assoc. Prof. Wenresti Gallardo (Sultan Qaboos Univ., Oman), Assoc. Prof. Stenly Wullur (Univ. Sam Ratulangi, Indonesia) and Dr. Erick O. Ogello (Kenya Marine Fisheries & Research Inst.). I am indebted to the Late Dr. Helen Marcial for her infinite support to our laboratory.
