Abstract:

In response to the decline of offshore fishery resources and the problem of remote management of marine ranching, and promote the construction of intelligent marine ranching, this study reviews the application of Internet of Things (IoT) technology combined with big data, cloud computing, artificial intelligence and other technologies to provide technical support for the management of marine ranching in aspects of water quality ecological environment monitoring, water quality ecological environment prediction and early warning, anti-theft systems, traceability systems, remote sensing, intelligent monitoring, detection and cleaning of net cages, and object recognition. At present, there are still four key bottlenecks in the application of Internet of Things technology in marine ranching. First, the standard of Internet of Things in marine ranching is lagging behind, which leads to difficulties in equipment interconnection and data sharing; second, the sensor has insufficient adaptability, high cost and difficult maintenance; third, the reliability of data transmission is poor and the efficiency of massive data processing is low; fourth, the security mechanism is lagging behind, there are security risks; fifth, the lack of compound talents restricts the landing of technology. Based on the above issues, targeted countermeasures are proposed: strengthening standard construction to gradually achieve interoperability and sharing; enhancing security research to ensure application safety; and establishing multi-party collaboration between government, industry, academia, and research institutes to cultivate and train talents. This study comprehensively summarizes the application progress and core issues of Internet of Things technology in marine ranching, and provides theoretical reference and technical support for the standardized and efficient development of intelligent marine ranching.
