The aim of the study was to establish a circulatory system for integrated cultivation of fishes, shrimps, shellfishes and algae. There are three ponds with respective organisms in one circulation system: white shrimp, Peneaus vannamei, was the major cultured objective; oyster, Crassostrea gigas, and algae, Gracilaria, were responsible for absorbing the suspended organic matter and nutrients in order from the shrimp’s pond and stabilizing the water quality. Pre-experiment showed that both 4 and 6 serial of oysters significantly reduced content of chlorophyll a in 8-ton ponds. Our study indicated that after being circulated by the system, the water quality could be effectively improved. The chlorophyll a concentration decreased by 20.4% in shrimps’ ponds, and increased by 129% and 58% in the oysters and gracilaria ponds, respectively. Plus, chemical factors such as pH, NH+4-N and NO2-N in the ponds were maintained within standard values.
