Demand for shrimp is growing throughout the world, with Japan and the U.S. being the largest importers. Production has rapidly increased to meet this demand, with cultivation flourishing in Southeast Asia in particular. This has resulted in environmental problems and a shortage of shrimp spawners; thus, new means of stabilizing the industry are needed. I am conducting basic and applied research with this objective in mind. This includes basic physiological research on reproduction, molting. and osmoregulation, and the development of technology to control female maturation in captivity. Another application of my research is the development of land-based recirculating shrimp production systems and their implementation on an industrial basis.
During 1995-2003, I was involved in an international development project on freshwater prawn farming in the Mekong Delta region of Vietnam in cooperation with Vietnam’s Can Tho University. We developed new, cost-effective hatchery technology for the giant freshwater prawn, which is an important commercial species in this region, and assisted rice farmers with culturing prawns in rice paddies, e.g., “rice-prawn farming”, a form of combined farming technology.
I have also been instrumental in developing Japan’s first “Indoor Shrimp Production System (ISPS)” in cooperation with International Mariculture Technology Co. Ltd. The system is currently under commercial operation in Niigata Prefecture.
