Far-reaching Marine aquaculture has great potential

Liu Xinzhong, Director of Fisheries Administration of Ministry of Agriculture and Rural Affairs

Food is the life of the people. Food security is a "national priority". The report of the Party's 20th National Congress pointed out that it is necessary to establish a big food concept, develop facility agriculture, and build a diversified food supply system. Aquatic products are important agricultural products, providing 30% of high-quality animal protein for Chinese residents, and ensuring the stable and safe supply of food and important agricultural products has always been the top priority in building an agricultural power. In 2023, the Central Document No. 1 proposed to develop deep water cages, aquaculture vessels and other far-reaching Marine aquaculture. Therefore, we should adhere to the concept of big food, develop deep sea space suitable for fishing in multiple ways, ask for food from the sea, and continuously improve the level of stable production and supply of aquatic products, so as to make contributions to the fishery industry for comprehensively safeguarding food security.

It is of great significance to develop far-reaching Marine aquaculture. Aquatic products are one of the three major animal foods alongside livestock and poultry meat and eggs, and are an important source of high-quality protein for human beings, which is conducive to improving national dietary structure and improving national physical fitness. Mariculture is an important part of the supply of aquatic products in China, accounting for 1/3 of the total output of aquatic products. In recent years, with the economic and social development, Chinese residents' demand for seawater products has increased rigidly, but the current offshore aquaculture capacity tends to be saturated and the new space is very limited. In the perspective of big food, the vast ocean is the blue granary, and the space potential for ensuring the stable and effective supply of aquatic products lies in the profound sea. With the development of productivity, the level of equipment and technology of mariculture facilities has been further improved, and it is more able to engage in far-reaching mariculture and raise the output of high-quality aquatic products, which can play a ballast role in national food security. The development of far-reaching Marine aquaculture is also an important measure to protect the "blue land" and safeguard the national maritime rights and interests, and actively develop far-reaching Marine aquaculture overseas is an important part of the implementation of the "Belt and Road" initiative and promote the aquaculture industry to go global.

China's far-reaching Marine aquaculture is developing vigorously. In the 1990s, China began to introduce and promote the application of gravity cage, which has become the most important and mature aquaculture model. Since the "13th Five-Year Plan", driven by policy guidance, scientific and technological progress, and market demand, far-reaching aquaculture has accelerated its development, especially the rapid development of large-scale equipment aquaculture such as truss cages and aquaculture workers' boats. Coastal provinces such as Shandong, Guangdong, Fujian and Hainan have set off a boom in the construction of large equipment and entering the far-reaching sea. We have successively built and operated more than 40 landmark truss cages such as "Shenlan 1", "Dehai 1", "Penghu", "Fubao 1" and "Jinghai Series" and a 100,000-ton "Guoxin 1" aquaculture ship. At present, the country's deep-water aquaculture water body 43.98 million cubic meters, the output of 390,000 tons, an increase of 3.3 times and 2.4 times than the early "13th Five-Year Plan". At the same time, with the upgrading of supporting facilities and equipment, the level of mechanization, automation and intelligence of mariculture has also been significantly improved.

Far-reaching Marine aquaculture development focus. Our country has the basis, advantages and huge potential to develop far-reaching sea aquaculture and practice the concept of big food. We should adhere to market-leading, scientific layout, scientific and technological guidance, green ecology and safe development, and build Marine pastures and "blue grain silos" steadily and orderly. First, to ensure security. Safety is the premise of development, the profound sea conditions are complex, the wave flow is urgent, to ensure the safety of breeding personnel, breeding equipment, breeding organisms is crucial. The construction of far-reaching Marine aquaculture equipment shall meet the technical requirements of relevant norms and standards, and carry out inspection registration according to law. Deep sea aquaculture producers and operators need to implement the main responsibility, strengthen production safety measures, and do a good job of risk prevention. Second, improve technology. We will strengthen innovation and research in the aquaculture seed industry, independently select and breed fishery varieties suitable for China's far-reaching Marine aquaculture, develop high-quality and efficient compound feeds, and do a good job in early warning and diagnosis and treatment of diseases. Strengthen the research and development of key facilities and equipment such as wind and wave resistant equipment, high-strength anti-adhesion mesh clothing, and mechanized fish harvesting, and constantly promote the transformation and upgrading of far-reaching Marine aquaculture to information, intelligent and modern. Third, preserve ecology. Adhere to the coordination of production and ecology, the development of far-reaching Marine aquaculture should meet the requirements of territorial spatial planning and the planning of aquaculture waters and beaches, and obtain the Certificate of real estate rights and the Certificate of Aquaculture Waters and beaches in accordance with the law. Carry out environmental assessment according to law, scientifically determine the farming mode, variety and density according to the environmental carrying capacity, standardize the use of legal veterinary drugs, feed and feed additives, equip the farming environmental protection measures and use according to requirements, and protect the Marine ecological environment. Fourth, pay attention to economy. Taking economic applicability as the fundamental starting point, in the future, China's far-reaching Marine aquaculture will still be dominated by gravity cages with mature technology and economic applicability, supplemented by truss cages and supplemented by aquaculture workers' boats. Establish a joint agriculture belt agriculture benefit agriculture mechanism, improve and promote the modern facilities suitable for fishermen small-scale Marine aquaculture, encourage the truss type cage and aquaculture platform, gravity cage "1+N" combined development of integrated farming mode, and promote fishermen to share industrial value-added income. Actively develop far-reaching Marine aquaculture social services to promote the industry to improve quality and efficiency.
