及ぼす。2. Description of the Related Art Generally, blue tide may occur in the inner part of the bay in summer. The blue tide is stratified in the summer, and when the bottom water is in an oxygen-deficient state, the bottom water rises to the coastal area due to the action of the shore wind, and the oxide ions contained in the bottom water come into contact with oxygen. As a result, it is a phenomenon in which seawater becomes bluish white due to oxidation. Since bottom water is anoxic, clams and fry that live in shallow water will die, and marine resources will be seriously damaged.
【０００３】このため、青潮防止対策が必要であるが、
現在、直接的な青潮防止対策の技術はなく、間接的な方
法として、養殖場等に瀑気をして酸素を供給する方法が
試みられている程度である。Therefore, it is necessary to take measures to prevent blue tide.
Currently, there is no direct technology to prevent blue tide, and as an indirect method, a method of supplying oxygen by defying water to a farm or the like is being attempted.
