Salmon is a fish of the genus Salmonidae of the order Salmoniformes. Salmon is a marine fish, living in the ocean, mainly distributed in high latitude waters. After developing in seawater for 3-5 years, they will breed and lay eggs in fresh water. Their dorsal fins are short, and they have scales on their bodies, but the scales are smaller. Their teeth are very developed, with teeth above the tongue and near the palatine bone. First, what kind of fish is salmon? Salmon, also known as "northern trout", is a famous fish living in China. According to the category, salmon belongs to the genus Salmonidae of Salmoniformes. This kind of fish has prominent appearance characteristics and short dorsal fin. There are scales, but the scales are relatively small, and there are many lateral line scales in the scales. They have teeth, and they are very developed, such as teeth above the tongue and near the palatal bone, which can play an important role when they eat. The color characteristics of salmon are also prominent, because their color is red.

Salmon belongs to marine fish, which can adapt to life in seawater and stay in seawater for a long time. Specifically, salmon has requirements for water temperature. They are cold-water fish, so they are mainly distributed in higher latitudes. Especially in some countries around the northern Pacific, the number of salmon living is relatively large. After 3-5 years of development in seawater, they are basically sexually mature, and then they will breed in fresh water. Salmon is also an edible fish species, which is rich in protein, minerals and trace elements.

Second, where does salmon grow? As mentioned above, salmon itself is a kind of marine fish, but they don't stay in seawater all the time. In different stages of their growth and development, the water environment in which they grow is also different. In the first 3-5 years of salmon's growth, they usually grow in seawater, and it is in relatively high latitude seawater. In addition, salmon is a deep-sea fish, which grows in deep seawater. However, when they are sexually mature and about to reproduce, they will go to fresh water. For example, there may be more salmon growing in Heilongjiang in China.
