Ocean is a natural extension of land through watersheds. In marine development activities, production links such as marine fishing, marine transportation, marine mineral development and marine aquaculture are jointly completed in the sea and watersheds; while the sea salt industry and seawater utilization are completed on the land. In addition, the development of modern science and technology promotes the progress of marine science and technology and the development of marine industries. At the same time, the development of marine high-tech and the emergence of new products have also promoted the scientific and technological progress of the basin and the development of related industries. Products are interactively developed through this technological extension.
