Among them, grass carp, which is of high quality, low price and delicious taste, is the first choice of many people. At this time, grass carp has experienced a winter of light and graceful harvest, and both the meat texture and nutritional content can reach the best. , plus it is very cheap, as one of the nutritious meat foods, it is really hard to refuse.

There has been a widespread saying among the people that "crucian carp is eaten in spring and silver carp is eaten in summer". Simply put, crucian carp is eaten in spring and catfish is eaten in summer. There may be some truth to this. Grass carp has the functions of strengthening the spleen, stomach and blood. The effect of dehumidification diet therapy is that people are more likely to feel sleepy especially in spring, so eating crucian carp is just right. Grass carp in spring is tender and not greasy. Whether it is braised or stewed, you can taste the delicious flavor of the fish itself. Therefore, when buying fish, you can also consider grass carp.

However, when you buy grass carp, there is a big difference between "soil crucian carp" and "engineering crucian carp". You need to understand them before buying to avoid being cut off. Many people may ask, what is engineering crucian carp?

There are two known species and one subspecies of grass carp in my country, namely crucian carp, black crucian carp, and silver crucian carp. These three are relatively early species and are known as soil crucian carp, while engineering crucian carp is It is a cultivated species, mainly referring to the Xiangyun crucian carp. This engineering crucian carp is a triploid grass carp successfully cultivated by Professor Liu Jun, a professor at the Chinese Academy of Engineering and the Department of Biology of Hunan Normal University. What is the difference between "earth crucian carp" and "engineering crucian carp"?

1. The engineered crucian carp has a taller body shape and can grow 3 to 5 times faster than ordinary grass carp species for the same feeding time. Now the larger fish species can grow up to 1 catty and 5 taels per person, while ordinary grass carps can grow up to 1 pound and 5 taels. Grass carp is much smaller in comparison, especially crucian carp weighing more than 1 kilogram is rarely seen. If you encounter a relatively large grass carp, you can basically judge it to be engineering crucian carp.

2. There are also differences in appearance design between earth crucian carp and engineering crucian carp. Engineering crucian carp is generally 1.5 times the body length, the body length is 2 times the body strength, the head length is 2.7 times, and the tail peduncle is 4 times the length. The head length is 1.6 times as strong as the head. It also has a pair of tiny barbels on the top of its head, which are not found on native crucian carp.

3. The order of fish scales is also different. The order of the scales from its dorsal fin to the tail end is relatively confusing. The order of the soil crucian carp is also relatively neat. In addition, we can see its small tail. , Engineering crucian carp has a very long tail, but earth crucian carp generally does not have such a thing.

4. You can look at the belly of the fish. The belly of the native crucian carp is very large, and the proportion of internal organs is also very large. The kidney ducts of the engineered crucian carp are small, and the muscle tissue is indeed thicker than that of the native crucian carp. At the same time, the thin spines of engineered crucian carp muscles are non-existent.

Therefore, it is easy to distinguish between "earth crucian carp" and "engineering crucian carp". Engineering crucian carp has a big body and small belly, disorderly arrangement of fish scales, long tail, very small random spines, and the edible part is very high; The body shape of native crucian carp is generally large with a big belly, neatly arranged scales, a short tail, many random spines, and a slower growth rate.

If it is stewed, I recommend the engineering crucian carp. It has more meat texture and fewer thorns. You don’t have to worry about getting stuck when drinking. If you are making soup, I recommend the earth crucian carp. , it grows slower, has richer nutrients, and has more flavor.

How to select grass carp:

1. When choosing grass carp, it should not be too big or too small. It is best to choose a grass carp that is about 70 to 80 taels. This type of grass carp is more suitable. When cooked, it is in the golden period of growth, and the meat texture is round and delicious. If it is too small and has too many thorns, it will not be delicious, and if it is too large, the texture of the meat will not be smooth.

2. Try to eat it before March and April in spring. This is the fish breeding period. The fat and other nutrients in the fish body are more abundant, and the meat tastes more delicious and has the best taste.
