The Department of Aquatic Bioscience has the following major aims.

First, given the global scale of the havoc wreaked on the environment by mankind, ways must be found to preserve aquatic ecosystems. Second, the development of selfsustaining fisheries must be striven for, and third, using among other things the knowledge from other fields such as biotechnology for varying applications including food production, we must investigate ways to contribute to the welfare of the human race. These are just some of the major research themes we are striving to fulfill.

At our laboratories, which include the Fisheries Laboratory in Hamanako and the Ocean Research Institute, we have been tackling these problems day in and day out and have achieved many encouraging results.

However, the ocean, which has spawned and nursed life as we know it since the Earth’s formation, is vast and as yet only partially understood. There is a real need to once again observe biological phenomena in the oceans from a fresh viewpoint and with open minds.
