Background and objectives of activities
South Kyushu waters, including Kagoshima Prefecture, are surrounded by a diverse range of marine areas, from deep to shallow waters, from inner bays and inland seas to the open sea. Fisheries resources obtained from these areas are used in the fisheries and food industries, which are also key industries in the Southern Kyushu region. On the other hand, pollution of the aquatic environment has become a problem in recent years, especially eutrophication and the resulting red tide, which have caused significant damage mainly to the aquaculture industry. In addition, with global warming, there is concern about the transfer of red tide-causing algae from tropical and subtropical waters.
Summary of Activities
The study of the mechanism of red tide occurrence is being conducted through on-site investigation of water quality and red tide-causing algae using the annex training ship NANSEI-MARU and other vessels. In addition, we are working on the development of a method for early detection of red tide and a red tide control agent using biological materials.
Expected Benefits
Based on the results of this research, it is expected to contribute to maintaining the sustainable use and development of fishery resources by applying this research to areas where red tides occur. In particular, it is expected to contribute to maintaining sustainable development of the aquaculture industry and to local communities and government agencies that support the aquaculture industry.
