TOKYO UNIVERSITY OF MARINE SCIENCE & TECHNOLOGY, DEPT OF MARINE BIOSCIENCES

Research Group: Fish physiology
Research Application: Fertility control, spawning control, broodstock management
Scientific Interest: Gamete physiology, gonad physiology
Description of research: Development of surrogate broodstock technology in fish by germ cell transplantation; one of the final objectives of this study is to make surrogate mackerel recipients produce bluefin tuna gametes. Cryopreservation of fish germ cells; since there is no cryopreservation technique for fish eggs and embryos currently available, this will be a breakthrough for preservation of fish genetic resources. In vitro culture of fish germ cells in order to use them as an alternative to ES cells. Analysis of endocrine control of fish germ cell proliferation and differentiation.
