Outline of our laboratory: Marine food & energy production and ecosystem preservation


Our laboratory launched in April 2002. We study on marine food & energy production and ecosystem preservation. Based on hydrodynamics, we study with many universities, institutes, and private companies by a combination of numerical simulation, tank model test, and field investigation.

First we have developed a hydrodynamic and ecosystem coupled model. The purposes of the hydrodynamic and ecosystem coupled model is to interpolate the observations in time and space for understanding the mechanism of variations in environment, and to predict the future ecosystem for environmental impact assessment and management. We are improving the numerical model and calibrating the parameters from field observations. Our students also take part in field investigation to understand the accuracy of the observations. We have developed hydrodynamic and ecosystem coupled models for Tokyo Bay, Lake Biwa, Lake Kasumigaura, Lake Ikeda, Caspian Sea, and a pond for shrimp aquaculture. We also study on modeling of an individual marine organism.

We have started the study on a marine food production system or aquacultural engineering since 2007. We took part in the project of offshore submerged aquaculture - development of underwater feeding system - during 2007 and 2009, and developed a feeding barge ship. Then we started the study on a flotation/submersion system of fishing gear. Actually, we are testing a flotation/submersion system of a fish cage to escape from severe wave condition due to typhoon attack and to culture fish in an appropriate water temperature. We are also testing an automated net-hauling system in set net fishery. We aim at improvement and automation of fisheries in harmony with ecosystem and human.

Further, we have started the study on marine renewable energy since 2012. We are developing a motion-controlled ship by wave energy and a innovative wave energy device. Environmental impact assessment of marine renewable energy devices is also a key study issue in our laboratory.
