The Yangtze River spans the third-class China landform with a drainage area of 6,543,800 square kilometers, which is connected with the largest wetland ecosystem in China.

"Since the 1980s, many rare animals in the Yangtze River, such as white dolphins and paddlefish, have quickly disappeared." At present, the white dolphin has been declared functionally extinct, and the Yangtze sturgeon was officially declared extinct by the World Conservation Union on July 2, 2022, but in fact, these two species have never appeared since 2003.

I've seen the rich Yangtze River before, and I've shocked the giant fish before. It's strange that I can't see their Yangtze River. In fact, in 2003, the fishery department stipulated that the middle and lower reaches of the Yangtze River would be closed to fishing for three months from April to June every year.

Fishermen change careers, get proper placement, and completely ban fishing has played a very good role, but it is far from enough. At the age of 88, he still knows the living conditions of fish in the Yangtze River like the back of his hand. "The list of key protected wild animals updated in 20021added dozens of fish as protected animals, indicating that their living environment has deteriorated and needs further protection."

After the initial achievements in the protection of the main stream and big fish, he will focus on the protection of tributaries, Tongjiang lakes, water level fluctuation areas and small fish at this stage and the next stage.
