Currently, China’s aquaculture industry is mainly based on aquaculture, supplemented by fishing. In 2022, freshwater aquaculture accounted for 47.91% of aquatic production, marine aquaculture accounted for 33.14%, and fishing accounted for 18.94%. In aquaculture, the yield of fish farming accounted for 52.16%, showing a pivotal position. “Improved seed, healthy aquaculture and high-quality sales” are the three important components of the aquaculture industry. “Improved seed” is the leading part of the aquaculture industry, “healthy aquaculture” is the guarantee of the aquaculture industry, and “high-quality sales” links such as processing and sales are the important driving force for the development of the aquaculture industry. Since the 1950s, China’s aquaculture industry has made great progress, which has provided rich aquatic products for the broad masses of people and solved the problem of “difficulty in eating fish”. However, at present, in China’s aquaculture industry, there are problems such as having varieties but with imperfect market and insufficient industrialization or having an industry but no high-quality varieties, and the problem of “eating good fish” and “eating safe fish” has not been fundamentally solved. In order to accelerate the development of China’s aquaculture industry, the authors believe that it is necessary to establish and implement a system of improved seed, healthy aquaculture and high-quality sales, so as to contribute to the high-quality development of the aquaculture industry in our country.
