Today is July 23, according to the latest news, China's Yangtze River white sturgeon officially declared extinct, this news can be said to be very painful. The Yangtze River white sturgeon is known as the Yangtze River inside the giant panda, can be said to have a very high research value, and the Yangtze River white sturgeon body snow white, very beautiful. In fact, the Yangtze River white sturgeon was last discovered in 2003, when scientists put a trap on its body, and then the signal of this trap disappeared. I did not expect to hear the news of the Yangtze River white sturgeon again, but it has become a goodbye, so why the Chinese sturgeon reasonable breeding has been released after 7 million, but the Yangtze River white sturgeon can not?

First, the Yangtze River white sturgeon character and the Chinese sturgeon is not the same, the Yangtze River white sturgeon like to go against the current in the upper reaches of the spawning, and Gezhouba Dam blocked the Yangtze River white sturgeon spawning place, so the Yangtze River white sturgeon has been functionally extinct According to the report shows that the Yangtze River white sturgeon every year, the Yangtze River white sturgeon will come to the lower reaches of the Yangtze River to foraging as well as the activities of the Yangtze River white sturgeon and the Yangtze River white sturgeon's food is mainly other fish. But the Yangtze River white sturgeon after maturity, spawning place is in the upper reaches, so that the Yangtze River white sturgeon will choose to go upstream to spawn, and Gezhouba Dam just blocked the Yangtze River white sturgeon to go, the Yangtze River white sturgeon has no place to spawn, basically declared functional death, so that the Yangtze River white sturgeon natural and Chinese sturgeon is different, can only silently extinct.

Secondly, the number of Yangtze River white sturgeon found is too rare, and our technology matured too late, so that the Chinese sturgeon can be cultivated, white sturgeon can't Our technology is in the 21st century, but that time the Yangtze River white sturgeon is only found one, Not enough individuals, there is no way to artificially cultivate, and the previous Although the Yangtze sturgeon was found in abundance, we actually did not have enough technology to cultivate the Yangtze sturgeon in time. Chinese sturgeon, on the other hand, when our technology is mature there are still catching the number can support, so the Chinese sturgeon to survive.

Hopefully, the Yangtze White Sturgeon can still survive in some undiscovered corner!
