as Duochun fish? Smelt and Duochun fish belong to fish species living in our country, but many people have not heard of them, because they are not particularly famous. This is because the number of this kind of fish is relatively small, so it is not very common. Specifically, the smelt refers to the fish of the genus Smelt of the family Smelt of the order Salmoniformes of the class Osteichthyes. They also have some nicknames, such as "spring fish". That is to say, the smelt and the spring fish refer to the same kind of fish, and the category referred to is exactly the same, but the name is different.
This kind of fish is quite famous in Japan, and its origin is in Japan. Their bodies are long and flat, their mouths and eyes are large, their dorsal fins are high, and their tails are thin. It is very small, and its body length is generally not more than 10 centimeters. Their main distribution area is the northern Pacific Ocean. In terms of feeding habits, they are omnivorous, but they mainly eat plankton, such as rotifers, copepods and so on. This kind of fish usually appears in the form of groups, and when it appears, it is more spectacular.
between smelt and spring fish? As mentioned above, smelt and spring fish are different names for the same kind of fish. Therefore, if we only look at the scope of the two, they are exactly the same, and there is no difference. Smelt fish and spring fish refer to the fish belonging to the genus Smelt of the family Smeltidae, order Salmoniformes, class Osteichthyes, which contain exactly the same species, and the appearance characteristics, distribution, habits and other characteristics of the fish species are exactly the same.
The only difference is that the names of the two are different, the angle of naming is different, and the application is different. The name smelt is based on the category, because this fish belongs to the smelt family smelt, the name also belongs to the scientific name, the application is more common, relatively more popular. The name Duochun fish is based on the reproductive characteristics of the fish, because the female fish has a lot of eggs in its stomach, so it is named. The name is an alias and is therefore less commonly used than a scientific name.
