The continuous application of the Internet of Things (IoT) technology in industrial aquaculture is conducive to the automatic aquaculture information collection, intelligent aquaculture equipment control and scientific aquaculture process management. Combined with the domestic and international relevant literature and field survey data, this paper analyzes the present situation of application of IoT in industrial aquaculture  in view of the communication technology, equipment, intelligent management, summarizes that the current development trend is the NB-IoT wireless communication technology, low cost and maintenance-free sensors, equipment control based on model prediction, low power development mode of whole system architecture and highly integrated aquaculture management system, and puts forwards suggestions for development from the aspects of national policy, equipment localization, demonstration base establishment, application system performance, talent cultivation and enterprise information management, so as to provide reference for the application of IoT technology in industrial aquaculture.
