It is an important problem to maintain and increase marine bioresources such as fishes and algae, in addition to the conservation of marine ecosystems. This academic course aims to conduct education and researches in biodiversities, genetics, physiology, ecology, ethology and pathology of marine creatures at the level of gene, cell, individual, population and ecosystem respectively, for the establishment of new techniques in resource management, fisheries techniques and effective sustainable use of marine bioresources. In addition, National Research Institute of Aquaculture (a Cooperative Graduate School of Mie University) also performs education and researches for the elucidation of biofunctions and genome analysis of marine creatures and their effective use in the field of developmental genetics, breeding science, and nutrition and metabolism.
