Research Interests:

Endangered fish conservation

Wild populations of fishes have been dramatically declined worldwide since the industry revolution. Many of fishes, particularly ones with large body and living in freshwater, became endangered species, such as sturgeons and paddlefishes. We focus on (1) in situ conservation by locating and characterizing the key habitats with modern methodology, such as telemetry and hydro-acoustic survey, we propose to protect or recover those areas located, such as spawning, hiding and foraging, which are significant in completion of life cycle; (2) ex situ conservation by exploitation of aquaculture techniques to restock offsprings into their habitats or to develop a captive population in fish farms or aquarium to save the live gene poor in case of wild population expiration; (3) new technique exploitation for saving critical endangered species, of which live specimen are hardly found out. Techniques may include in cryopreservation of sperm, cell culture, gynogenesis or androgenesis, surrogate breeding, as well as techniques for inducing pluripotent stem cells (iPS).

Sustainable aquaculture of sturgeons

Sturgeons have both scientific importance and highly economic values. We use the technologies, which we developed to rear endangered sturgeons, to commercial farming of sturgeons which are relatively of low threatened species among species of Acipenseriformes. We focus on (1) controlled reproduction from full life-cycle culture; (2) rearing mode studies for sustainability of both sturgeon aquaculture industry and environments; (3) technological studies of nutrition and disease prevention.
