sturgeon? Chinese sturgeon is a very precious fish living in China. It belongs to the Chinese sturgeon species of the family Acipenser, order Acipenseriformes, class Osteichthyes. The reason why Chinese sturgeons are named Chinese sturgeons is closely related to their living areas and habits.
From the point of view of living area, Chinese sturgeon mainly lives in our country, which can almost be said to be a unique species in our country, so the name of "China" is closely related to the characteristics of Chinese sturgeon. Chinese sturgeons not only live mostly in China, but also in the Yangtze River Basin. Although there are Qiantang River, Pearl River and other river basins, the number is relatively small, only occasionally. From the point of view of habit characteristics, Chinese sturgeon has the attribute of migration. Chinese sturgeons sometimes live in coastal areas, but when they breed, they return to the Yangtze River. That is to say, Chinese sturgeons will return to their homeland when they reproduce, and people have fully considered this habit when naming them.
? As mentioned above, Chinese sturgeon is a precious fish because its number is very small. There are many reasons for their decline and extinction, although there are also changes in natural environmental factors, but the main reason is human factors. Among the human factors, environmental pollution is a very important aspect, and the water quality has deteriorated to the point that many Chinese sturgeons have died. In addition, human overhunting is also one of the important factors leading to the sharp decline in the number of Chinese sturgeons, which directly leads to the death of a large number of Chinese sturgeons. The construction of water conservancy projects also has a great impact on the reproduction of Chinese sturgeon, resulting in the reduction of their reproductive efficiency.
