Water cod has high water content and loose meat. From the appearance, the two kinds of fish are slightly different, and there is a big difference in nutritional value. In terms of price, it is also a world of difference. Water cod or another kind of oil cod pretending to be silver cod costs more than ten yuan or even several yuan a catty, while the real deep-sea silver cod costs at least 80 yuan a catty, and the good quality cod costs 120 yuan or even more.

The main types of cod in the market are silver cod, water cod and dragon cod fish. Water cod is a kind of deep-sea fish. In scientific classification, it only includes three species of cod in a narrow sense: Atlantic cod, Pacific cod and Greenland cod, and in a broad sense it can include all the fish in the order Codiformes.

Among the silver cod, dragon cod, water cod, real cod and narrow cod on the market, the silver cod has the highest nutritional value. Silver cod (scientific name: skinfish, Cetactera-Cetaceae-skinfish) is named "Silver Cod" by the Japanese market because it looks like cod, and its price is much more expensive than that of real cod.

Extended data:

Silver cod grows in the cold and pure deep sea, with high oil content, rich in DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid), and also contains iron, zinc, vitamins A, D, E and other vitamins necessary for human body. It is called "nutritionist on the table" and "liquid gold" because of its high protein, low fat and easy absorption. Suitable for five categories of people: pregnant women, infants, teenagers, white-collar workers and middle-aged and elderly people.

DHA, commonly known as "brain gold", can promote the growth and maintenance of nervous system cells, and promote the development of brain and retina. The content of DHA in human cerebral cortex is as high as 20%, accounting for the largest proportion in the retina of eyes, accounting for about 50%. Therefore, it is very important for the intelligence and vision development of fetuses.

EPA, known as "vascular scavenger", can enhance the disease resistance of middle-aged and elderly people, reduce the cholesterol harmful to human body in the blood, and maintain the low-concentration blood lipid level, thus reducing the incidence of diseases such as hypertension, arteriosclerosis, heart disease and cerebral thrombosis, and maintaining good health? .
