By means of deploying artificial reefs, constructing algal reef and seaweed beds, stock enhancement, acoustic domestication and ecologic management, construction of marine ranching is able to promote marine productivity, increase resource density, control behavior of fish, produce at scale, realize sustainable exploitation and utilization of fishery resource. It embodies the feature of modern fishery and low-carbon circular economy, which is an important direction of future fishery. Setting up artificial reefs is an important step for the construction of marine ranching. Since “The Tenth Five-year Plan of China”, offshore environment improvement, stock enhancement and mariculture development have been given very high degree of importance along the coast of Shandong province. Studies and tests on artificial reefs and marine ranching, including effect investigation of artificial reefs set up in Jiaonan coastal areas in 1980’s, hydrodynamic characteristics experiment of artificial reef, study on material and configuration of artificial reef models, algae transplantation and seaweed beds construction, stock enhancement and releasing etc., have been carried out in recent years. Furthermore, the Restoration Plan of Fishery Resources of Shandong Province has been implemented since the year of 2005, which greatly boosted the construction of artificial reefs and marine ranching along the coast of Shandong. By June of 2010, the number of artificial reef construction projects which were supported by government financial capital has been up to 21. Total investment is over 77 million USD. 100 artificial reef districts, with total area about 33,350,000 square meters have been set up. The total volume of artificial reefs has been up to 2,266,000 hollow cubic meters, among which, 1,537,900 m3 are stone reefs, 6,469,000 m3 are made of concrete and the rest comes from 334 retired ships. With four large scale artificial reef zones being established, the construction of marine ranching along the coast of Shandong province has been in certain scale and the economic, social and ecological effects are obvious.
