であった。[Problem to be solved by the invention] However, in these artificial ponds, the amount of dissolved oxygen in the water is not properly adjusted, so when the amount of dissolved oxygen in the water decreases, the fish in the water die due to oxygen deficiency. There is a problem that natural purification of organic substances becomes impossible and algal blooms occur, creating an environment that is difficult for fish to live in. Also, when the amount of dissolved oxygen in the water increases, it causes eutrophication of the water, causing water to become eutrophic. There was a problem in which fish died due to an abnormal abundance of plankton. As a result, it has been extremely difficult to manage the aquaculture.
