Abstract: Chinese fishery law enforcement command system is a large-scale management information system which provides fishery management operation services. Along with the development of fishery information construction and increasing demand of informatization, more and more fishery management operation services have been brought into the system, which brought new challenges to the operational efficiency and cooperativity. Through analyzing the key technologies, the researchers, based on methods of enterprise architecture (EA) and service oriented architecture (SOA), put forward the system architecture for fisheries management and optimized the overall design scheme of Chinese fishery law enforcement command system. Business architecture, data architecture, application architecture and technology architecture were designed according to the business demands and management strategy. The overall design of Chinese fishery law enforcement command system could effectively ensure the system’s flexibility, scalability and future compatibility to satisfy the increasing requirements and provided a model to realize the sharing and interconnection of fishery management information and collaboration of services.
