An indoor automatic aquaculture system has an indoor breeding pond constructed in a stepwise manner for breeding aquatic or marine products in a staged-breeding approach to increase breeding density and reduce required space. Breeding water is processed in advance by a recirculating water treatment system and water quality is constantly monitored by a water quality monitor and control system to maintain the breeding water at the optimum condition. A movable feed dispensing control system is located above the breeding pond for dispensing feeds evenly thereby to increase breeding survival rate, improve breeding yield and better control breeding product quality.
