The closed aquaculture Vessel is a floating closed aquaculture system at sea with an autonomous navigation function, and also a comprehensive marine fishery production platform. Its production function is mainly based on the closed "aquaculture on board" in the deep sea, and it has both primary processing and storage and transportation functions of aquatic products. The article reviewed the three stages of conceptualisation, the large closed aquaculture vessel the breeding idea of research and development experience, actively explore, and the development of innovation summarizes the research and development taken by industrialization idea in the process of constructing modern aquaculture new mode, pay attention to the depth of the modern equipment technology and aquaculture technology integration, strengthening the practice experience in related research achievements of patent strategy layout. After more than 30 years of exploration and development, China's large closed aquaculture vessel has finally become a reality from a dream. It has closed breeding, a controllable environment, and a high-quality green breeding method. Cruise farming, which can make full use of natural conditions, is an efficient production mode; Large-scale development, give full play to economies of scale, the construction of a comprehensive production platform, and other technical characteristics. In the future, a fishery aircraft carrier fleet will be formed around the closed aquaculture vessel, and a full-process, full-cycle, and full-chain aquaculture system will be built to realize the deep blue trend of mariculture.
