Wen/Farmer is also crazy
In recent years, the standard of living has improved, and there has been a higher pursuit of diet. In the past, seafood was generally only affordable to the rich, after all, in the past, the transportation and preservation costs of seafood were too high, so the price in the market was relatively high, unless it was some coastal cities. Now it's different, even in some farmers' markets in the countryside, you can buy seafood. When it comes to seafood, it is estimated that many people will see the living fish, so are knife fish and belt fish the same thing? Is there any difference? Why can't live fish be seen in rural markets?
(1) What is the difference between knife fish and striped fish?
In many coastal areas, knifefish is a striped fish, and striped fish is also called a knifefish, so there is no difference between the two. However, in some places, knifefish is different from striped fish, because in these places, knifefish refers specifically to a freshwater fish, such as the most famous is the Yangtze River knifefish. If this is the case, then there is a difference between knifefish and striped fish, and the first point is that the growth environment is different, knifefish can live in the sea, can also survive in freshwater areas, but the striped fish can only live in the sea, they will die when they leave the sea.
The second is that there is a difference in appearance. The fish, as the name suggests, looks like a long silver band. The body of the fish is very long, basically the same width from the head, but it suddenly becomes thinner at the tail, and the fish is a fierce fish. Not only is its body silvery-white, but its eyes are larger, protruding, and it looks fierce. In addition, the teeth of the fish are very sharp, which gives people a very fierce feeling.
Compared with the fish, the knife fish looks much quieter. It resembles a small sharp knife, and is generally not very large, and it is also silvery-white. Together with puffer fish and anchovies, it is known as one of the "Three Fresh Foods of the Yangtze River".
The third difference is the texture and texture of the meat. Knifefish have no fishy taste, the meat is very tender, fat and not greasy, but there are many fine hairy bone spurs. The meat is delicious, fat but not greasy, and slightly fragrant. The fishy smell of the fish is relatively heavy, its fish bones are also less, the nutritional value is very high, mainly has the effect of liver nourishment, wind removal, hemostasis, etc. In ancient times, fish can be used in medicine. However, the taste of the fish is worse, and it is often fried or braised in life. In addition, there are many types of knifefish, especially the Yangtze River knifefish, which is very rare and the price is quite expensive.
(2) Why are all the fish sold in rural markets?
The reason is actually very simple, that is, the striped fish is a deep-sea fish, and once it leaves the deep sea area, it will die. This is because the pressure of the deep sea is relatively large, and the striped fish have formed a physique to overcome the pressure of the deep sea, so it is very suitable for growing in the deep sea environment. And once the environment suitable for their survival is severe, it will die. This is the same as us humans, in the high oxygen-free environment, if you want to continue to survive, you must wear oxygen, otherwise you can not adapt to such an environment, and life will be threatened. The same is true for the fish, once they leave the deep sea area, the pressure on the ground is very small, and it is no longer suitable for the fish to survive, so the fish will die soon after they are caught. And if you want it to survive, you need to keep it in a high-pressure environment, and it is clear that such transportation costs are very high. Therefore, after the fish are caught, they will be frozen when they leave.
