Sturgeon is an ancient fish with many species. Some sturgeons live in seawater, while others live in fresh water. There are also some sturgeons with migratory habits. When they grow up, they will breed in fresh water. When the bred small fish grow up, the parent fish will lead the small fish into the ocean to live.

When sturgeon reaches adulthood and reaches the breeding age, they will return to fresh water again, so there is no accurate answer as to whether sturgeon is freshwater fish. But relatively speaking, there are more sturgeon species in freshwater, such as Acipenser sinensis, Acipenser schrenckii and Sakhalin Island sturgeon. Chinese sturgeon lives at the mouth of the Yangtze River. It will enter the Yangtze River to lay eggs during the breeding period, and then enter the seawater after laying eggs.

Sturgeon is not just Chinese sturgeon, there are many varieties of sturgeon, and Chinese sturgeon is only one of them. It can also be said that Chinese sturgeon is a kind of sturgeon, but not all sturgeons are Chinese sturgeon. Therefore, it cannot be said that they are completely different, they are closely related. Chinese sturgeon is a scarce species of sturgeon, which is mainly distributed in the Yangtze River basin of China and also distributed in other countries, but the number is small.
