Hokkaido is located to the north of the region where large number of jellyfish are seen, there were no outstanding problems with jellyfish and we didn't conduct any surveys about countermeasures. However, recently troubles by Nomura's jellyfish (giant jellyfish) has hit the fishery almost every year along the coast of the Japan Sea, including Hokkaido, and it is suggested that the troubles will continue to be seen in the future. In Hokkaido, a troubles by moon jellyfish has recently hit the fishery and similar troubles has been seen along the Pacific coast in the Tohoku region, which has not had huge problems with jellyfish before. Considering these situations, it is expected that jellyfish could greatly damage our coastal power plants in the future. Therefore, our department is conducting surveys on countermeasures against jellyfish at our coastal power plants.
We will propose appropriate countermeasures against jellyfish for our coastal power plants through the study and research on the following points that are needed when we consider the adoption of the method for loses jellyfish on the sea and quick waste treatment systems of inflowing jellyfish.
