Abstract: The fishing ports have played an important role in the economic and social development of fisheries and the adjustment of the industrial structure, where information technologies have provided new ideas for fishing port supervision, fishing vessel management, marine catches tracing, and environmental governance. In the present study, the research on the status of fishing port informatization included two aspects. One aspect was the current situation of fishing port information systems, which were classified into five areas, namely, video application, fishing vessel monitoring application, information management application, decision support application and government service application. The other aspect was the distribution of data resources and the problem analysis which summarized as insufficient data analysis, difficult in data collection, data inconsistent and uneven data distribution. A framework for fishing port information system, which including the bottom-up structure of information infrastructure, data management, technology stack and fishing port business, and information standard and safety as guaranteed, was established with the overall objective of sustainable development of the fishing port economy. Based on current fishing port information infrastructure, three stages of key technologies of fishing port informatization were proposed. First, as the next research direction of fishing port video monitoring system, the fishing port ultra-large-scale vision system brought challenges in data acquisition, processing, transmission, analysis and hardware stability due to the large number of fishing ports, huge amounts of data, rapid data changes, and the complex ecological environment of fishing ports. Second, the Fishing port cloud-end collaborative integration technology would build the intelligent perception of fishing port terminals and the rich computing resources in fishing port cloud. Third, the Single-multibody-ecological fishing port intelligent networking technology would provide applications such as overall perception of fishing port, interactive intelligence in fishing ports groups, intelligent scenes of fishing ports, collaborative intelligence between fishing ports and fishing vessel and ecological intelligence of fishing port groups. The research in this paper provided a reference basis for the planning and construction and management decision of the fishing port informatization in the next step. The future of fishing ports was not only the investment and construction of information hardware facilities, but also innovations in information applications. By constructing a fishing port cloud-end architecture and using data analysis as the core brain, it would create fishing port production management, fishing port economic zone construction, fishing port global planning, and more applications in multiple fishing port business areas.
