Question 2: The difference between eighteen-scale carp and Songhua fish Mirror carp, also known as eighteen-scale carp, is a variety of carp. Carp originated in China and was introduced to China. This kind of fish has few bones and thick meat.
Songhua fish, introduced from Germany, grows in Yalu River, and comes from snack pine pollen. Its pine pollen contains 268 kinds of active nutrients, hence the name "Songhua fish". The fish body is black and bright, with strong physique, less spiny scales, fresh and fragrant meat, tender and smooth skin, excellent taste and smooth roe. Fish is rich in more than 20 kinds of amino acids necessary for human body. It is the only precious fish with fish oil in cold water fish and a rare healthy food for modern people.
Question 3: What is Songhua fish? Are there many fishbones? Well, it shouldn't be too much!
Question 4: The difference between pure Songhua River fish and farmed fish Some people say that farmed fish and wild fish can be judged by their body color, and there are many such experiences on the Internet. In fact, as far as my personal contact with vendors and actual fish farming experience are concerned, this experience is not reliable for many kinds of fish. The skin color of most fish can often change with the change of environment. In order to save face and pretend to be wild fish, many vendors have ways to change the skin color of farmed fish. The common practice is to put farmed fish in the river and mix them with wild fish for ten and a half months. When the skins of the two are no different, they can be fished up and sold as wild fish, which can fool most consumers. Another trick is the most direct and quickest, which can fool many consumers. That is to dye cultured fish with pigments, which come from a wide range of sources, including yellow mud water, red mud water, kaolin mud water and so on. It can also be used directly with chemical dyes. Many people think that artificial dyeing will discolor and pigment will be found in fish ponds. It's actually wrong. This kind of fish skin is not simply drawn, and it will not discolor and enter the water. To sum up, it is not reliable to distinguish wild fish from farmed fish only by skin color. Many aquatic experts can be caught in the middle of the night by the "technical" means of vendors, and the general public can only be fooled by skin color.
1. Body shape is an important reference for judging wild fish and cultured fish. Cultured fish are generally fat because of adequate feed and rich nutrition, while wild fish are often thin because of full competition in the natural environment.
Of course, it depends. During the spawning period, some wild female fish appear to have bigger stomachs because their eggs are full, and consumers who don't know them will mistakenly think that they are fat and strong. In fact, the belly of this wild fish due to the offspring can be seen by careful look. The belly only reflects the abdominal cavity, while the fat body of cultured fish is even and obese.
2. The fat content of farmed fish and wild fish is an important basis to distinguish them. Nowadays, fish feed is composed of high fat and high protein, and it is fed adequately. Therefore, the fat content of artificially raised fish is very high. Not only the abdominal cavity and fish intestines are full of fat, but even the skin of the fish may have a thick layer of fat, and even the belly of the fish is mainly fat. However, due to the lack of food, wild fish often have low body fat content, less intestinal and abdominal fat, and less fat on fish.
In addition, because of the high fat content in the feed of cultured fish, it will lead to high cholesterol, large gallbladder, more bile and strong color. Wild fish have smaller gallbladder, less bile and lighter color.
Because farmed fish eat artificially mixed high-fat and high-protein feed, and eat a lot, feed regularly and have low digestion and absorption rate, the excrement is often black and has a strong fishy smell. However, because wild fish eat pure natural food, and eat less, digest more fully, defecate color is lighter, and the fishy smell is much lighter. If you carefully observe the water quality of the fish pond, you can notice it.
For cultured fish, if the stall owner starves the fish to death, that is, if it is put in clear water for several days without feeding, then this trick will basically fail. Some impatient vendors immediately buy and sell. Such farmed fish pass off as wild fish. As long as it is slaughtered, careful consumers can see the doorway, pierce the fish intestines to observe undigested food and digestive residues, and find traces of fish feed.
Peritoneum is also the basis for distinguishing wild fish from cultured fish. Because of the feed and living environment, the belly of farmed fish often has a dark black film, while the wild fish has no black film or the black film is very shallow.
The number of wild fish is limited, while the number of cultured fish is huge. If a fishmonger sells a lot of wild fish all day long, he may cheat emotionally and intellectually. In order to deceive consumers, some fishmongers often hide a large number of farmed fish and put only a small amount of fish on the stalls, claiming that wild fish deceive consumers and take out some when they are sold out.
4. Wild fish often have strong viability. As long as the density is not very high, there is often no need for artificial oxygen supply, and the survival ability of cultured fish is poor. Once they leave the fish pond, they must be artificially supplied with oxygen. Therefore, in those stalls pretending to be wild fish, we often see oxygen pumps supplying oxygen.
In order to prove that the fish they catch is fresh river fish, fishermen in many places often sell them on river banks or docks after fishing, and many citizens will also buy them. However, some unscrupulous traders take a fancy to the business opportunities, and often go to the river to pretend to be wild fish or gang up to commit crimes. Everyone takes a small amount of fish to sell in riverside docks and streets, and then goes to the warehouse to get the goods after they are sold out. Therefore, they have been selling "wild fish" all day, but they have not seen their fishermen.
