Marine ranching constructions help improve the marine ecological environment and restore fishery resources. Jiangsu province is rich in marine natural resources and human landscape resources, whereas there are still some deficiencies in the construction of modern marine ranching. To accelerate the development of marine ranching, we must adhere to the development concept with ecology, precision, intelligence and integration. Fully exploit the marine natural endowments and cultural landscape resources of coastal cities to reasonable layout the development mode of marine ranching. Promote the formation of a new pattern of marine ranching with rational layout, advanced equipment level, standardized management, diversified industrial integration, high output efficiency, and green ecological development. Realize the precision and intelligence of marine ranching management, and then establish a relatively complete marine ranching construction management system and support system. As a result, form a new development situation of modern marine ranching with resource saving, environment friendly, efficient operation and sustainable output.
