Current Situation, Problems and Countermeasures of Marine Ranching Development in Guangdong Province, China

Combining the literature review and marine field investigation in the sea area, this article summarized the development and current situation of marine ranching at home and abroad. It analyzed the construction process of artificial fish reefs, proliferation and release, and national-level marine ranching demonstration areas, as well as the current development situation and existing problems of marine ranching-related industries in Guangdong Province. Guangdong has built 50 ecological artificial reef areas, 3 large-scale artificial reef demonstration areas, 1 local artificial reef area and 15 national marine ranching areas, with a total sea area of 1 499.68 km2, and 2.004 million m3 of reefs. However, there are some problems in Guangdong marine ranching, including imperfect management mechanism, inconsistence in development concept and understanding, unclear rights and responsibilities in using sea area, lack of construction technology standards and specifications, low scientific and technological level and limited industrial development. In view of these problems, this article came up with countermeasures, including insisting on ecology-prioritized development, and strengthening the coordination of multiple departments; creating a management mode conducive to market-oriented operation; breaking through the issue of sea area ownership; establishing a technical standard system for marine ranch construction in Guangdong; strengthening the research on the basis of high-quality construction and key common technologies of Guangdong marine ranching; establishing industrialization modes of Guangdong marine ranching according to local conditions. Understanding the development status of marine ranching in Guangdong and exploring the development strategies of marine ranching industry by referring to the relevant experience at home and abroad can provide references for the effective management, efficient and sustainable development of marine ranching in Guangdong and the integration of three industries in the development of marine ranching in Guangdong.
