Aquatic products are mainly derived from the two major areas of fishing and aquaculture. They can be divided into two categories according to the origin of production: seafood and freshwater products. With the rapid increase of the global population, the rapid growth of demand for aquatic products, the over-fishing of marine resources, and the increasing pollution of marine products, the supply of seafood has been continuously reduced, and the market demand has not been met. The aquaculture industry has been Rapid development.

　　In the global aquaculture market, China's aquaculture production accounts for more than 60% of the global market, and is the dominant force in the global aquatic market. China has a long history of aquaculture, with high farming technology and rich experience. Stimulated by the rapid growth of global aquatic product demand, China's aquaculture industry has developed rapidly and the scale of farming continues to expand.

　　Aquatic products can be divided into fresh products, frozen products, dry fresh products and deep processed products according to the processing methods. China's consumer market is mainly based on fresh products and frozen products, so it has higher requirements in the field of cold chain logistics. In the early stage, due to the imperfect technology of cold chain facilities, China's aquatic product consumption market is mainly concentrated in the production areas and coastal areas. With the gradual improvement of the cold chain logistics industry layout, the storage and transportation capacity of aquatic products has been greatly improved. While ensuring the fresh activity of aquatic products, the sales network of aquatic products has expanded to other regions outside the aquatic product producing areas, and the aquatic product consumer market. And gradually spread from coastal cities to inland cities.

　　According to the "Inner Depth Survey and Investment Prospects Analysis Report of Aquatic Products Industry in 2018-2022" released by the New World Industrial Research Center, the deep processing of aquatic products can improve the utilization rate of aquatic products and increase the added value of aquatic products. Come to more profit margins. China's aquatic product processing industry is still in its infancy. The consumer market has low demand for deep-processed aquatic products. With the acceleration of urbanization, the consumption concept and consumption level of residents have been continuously improved, and refined aquatic products have gradually been welcomed by the market.

　　Japan's aquatic products processing industry is relatively developed, and the aquatic product waste left after processing food is also effectively utilized. The use of aquatic product waste can be made into antihypertensive peptides, fish skin collagen, protamine and other products. Product resource utilization also increases industry profits. In contrast, China's aquatic products processing is relatively low, most of the processing technology is still in its infancy, the waste of aquatic product resources is serious, and the industry's profit level is low. Deep processing is the future development direction of China's aquatic product processing industry.

　　At the same time of supplying domestic market demand, China's aquatic products are also supplied in large quantities. Japan, the United States, South Korea, and the European Union are the major export markets for aquatic products in China. Similar to the domestic market, China's exported aquatic products are mainly fresh products and primary processed products. Although the export momentum is good, the added value of products is low, the profit margin is limited, and the product structure still needs to be adjusted continuously.

　　According to new analysts in the industry, with the economic development, the living standards of Chinese residents are increasing, the demand for aquatic products is growing, and the gradual improvement of cold chain facilities has made the coverage of China's aquatic products market expand rapidly. Under the background of the upgrading of consumption concept, the demand for deep-processed aquatic products in China and international consumers is rising. However, China's aquatic products are mainly fresh and primary processed products, the waste of resources is serious, and the overall profit rate is low, which cannot satisfy the market. Demand, industrial structure needs to be constantly adjusted and upgraded.
