1, the Yangtze River shad is not extinct. In order to protect the resources of the Yangtze River anchovy, China has carried out research on artificial insemination of anchovies, egg incubation and fecundity cultivation, and also put forward a short-term fishing ban on the Yangtze River anchovy since March 1987. 1988, the Yangtze River anchovy was listed in the Red Book of China's endangered animals.

2. The Yangtze shad had a high yield of 1.575 million kilograms in 1974, after which there was a serious decline in resources to only 30,000 kilograms in 1985

grams. The reason for the sharp decline in the natural resources of the Yangtze River shad is that water conservancy construction cut off the spawning and bait migration channels of the shad, overfishing and environmental pollution of the waters.

3. It is due to overfishing that the Yangtze shad population is out of balance and is functionally disappearing, so only if the Yangtze shad is allowed to get proper recuperation will the number rise and the population recover.

4, the Yangtze River anchovy was once a delicacy on the table of the Chinese people, with the swordfish, blowfish and known as the "Yangtze River three fresh". Since the Six Dynasties, due to the scholarly class and the literati, writing a lot of poetry and articles about the lower reaches of the Yangtze River, the formation of a long history of the city to taste the river's fresh fanatical hobbies, such as Su Dongpo ate dolphins to the death. As a result of heavy fishing, anchovies in the Yangtze River have basically become extinct, while the production of swordfish has also declined sharply, and the price is quite expensive. Puffer fish, which is naturally highly toxic, has been labeled as the most dangerous delicacy.
