Department of Bioresource Sciences

The mission of the Department of Bioresource Sciences is to overcome the food problem which is one of high-priority issues imposed on human in the 21st century. This Department offers education and research academic training covering on the sustained stable supply and innovative production techniques of the food bioresources including agricultural, animal and fishery products, conservation and management of organisms useful to mankind, and maintenance of ecosystems in the production fields. Basic, applied and advanced research at the levels from molecular to population is conducted on microorganisms and higher forms of plants and animals.
The Department consists of two educational courses; Agricultural Bioresource Sciences and Animal & Marine Bioresource Sciences, and subdivided into 19 laboratories. The main objectives of the educational courses are as follows:

Agricultural Bioresource Sciences: Graduate students are educated for plant production and physiology, genomic science of organisms, and pest-management to learn efficient utilization and preservation of agricultural bioresources.

Experimental biology on reproduction and recruitment of small marine pelagic fish

Genetics on mosaicism of the silkworm

Animal & Marine Bioresource Sciences: The aim of the course is to educate graduate students through the studies for the production, efficient utilization and preservation of domestic animals and marine organisms.
