In order to accelerate the healthy and sustainable development of deep-sea aquaculture in China and promote the spatial expansion of mariculture and the transformation and upgrading of marine fishery industry, the article expounds the current status of deep-sea aquaculture facilities, and equipment as well as technology in China and lists the latest technical progress and typical facilities of the main types of deep-sea aquaculture including gravity cages, truss-type cages and aquaculture vessels etc. Then in response to the technical requirements for the construction of deep-sea aquaculture system, the article clarifies the progress and development trend of science and technology innovation at home and abroad in the areas of breed cultivation, fry production, aquaculture facilities, and production management equipment, etc. The article further dissects the main problems existing at present, such as lack of good breeds, insufficient integration of disciplines, technical immaturity of facilities and equipment, as well as lack of standardization in design and construction based on the analysis on how to realize the sustainable and healthy development of deep-sea aquaculture in China. Last but not least, the key technical breakthroughs in species, facilities and equipment, and industrial chain are proposed to achieve safety, quantity and quality breeding, as well as deeper and farther deep-sea aquaculture in China, with the aim to provide reference for accelerating the sustainable development of deep-sea aquaculture in China.
