[0002] Fresh water aquaculture refers to the aquaculture activities of aquatic organisms in fresh water environments. Fresh water aquaculture has the advantages of rich resources, relatively low costs, diverse aquaculture varieties, and large market demands. During the process of fresh water aquaculture, automatic feeding can reduce the labor intensity and time investment of manual feeding. Aquaculturists do not need to perform feeding operations frequently and can devote more energy to other aspects of aquaculture management;
