One kind of monitoring system with function of tracing was designed to apply in industrialized aquaculture, data communication. It was accomplished via PROFIBUS—DP. Data from field were processed by computer with algorithm of fuzzy control and artificial neural networks, and control signals were produced to ensure the system to run in style of closed loop. The technology of radio frequency identification (RFID) was also applied into the system to realize function of quality tracing. Finally the results including the precision of dissolved oxygen and temperature, the scale of total ammonia and nitrogen and the scale of pH value showed that the system completely met the demand of industrialized aquaculture and the integrity. The validity of information of tracing system also met the demands.
