I survey the importance and influence on environment of aquaculture. Although aquaculture is an important fishery enterprise, its influence on environment cannot be disregarded, and must be improved considering maintenance of fishery environment. The closed recirculating aquaculture system is expected to solve this problem. I am evaluating the possibilities of the system to breed the high-class fish and to research for production increase of a fish to control environment, but I am apprehensive about the efficiency to the environmental problem of this system. I make, therefore, a semi-closed recirculating system proposal to flounder aquaculture.When Japanese flounder are bred in a culture tank on the ground, breeding water is usually kept pouring all the time. In my proposing system, only when load from the tank is larger, the breeding water is recirculated and treated. It is thought that introduction of this system is easy compared with the closed recirculating system, and will contribute to the improvement of fishery environment.
