Review of engineering and equipment technologies for deep-sea cage aquaculture in China

Abstract:

Owing to the major issues of pollution, limited resources, and restricted space for mariculture in coastal areas, it will be a significant advantage to develop large-scale cage aquaculture in open sea areas, which have the advantages of the finest water conditions. The vigorous development of scientific and technological innovation in deep-sea aquaculture plays a positive role in upgrading and transforming aquaculture methods and expanding the mariculture space. These lead to a new pattern of development of marine aquaculture facilities. Here, we present a summary of the status of China's cage culture industry, the demand for the development of the deep-sea cage culture industry, and the corresponding scientific and technological requirements of cage culture facilities and equipment. Then, research and applications in China and abroad are introduced in detail regarding two aspects: deep-sea cage culture facilities and related equipment and technology. Subsequently, the main problems faced in the development of deep-sea cage culture engineering and equipment in China are identified. Finally, suggestions are given for scientific planning, technological guidance, standardized construction, and innovative modes, for better development of the deep-sea cage culture industry. This review provides a reference for research and development of the deep-sea cage aquaculture industry in China.
