At the beginning of the new year of 2019, experts are busy on the banks of the river. They studied intently on a paddlefish, wrapped tightly around a fishing net. The strength of this fishing net is so strong that the skin and flesh of the white sturgeon are broken, and blood gushes out. Experts carefully cut the fishing nets and carefully treated the white sturgeon's wounds before releasing it back into the waters of the Yangtze River. Rescuing paddlefish is a good thing, but the look on the experts' faces is not optimistic. They bluntly said that the white sturgeon's injuries are too serious and huge, which will affect its recovery. Weighing 130 kilograms and measuring 3.3 meters, this paddlefish is the largest paddlefish found in the lower reaches of the Yangtze River in decades. However, when people found it, it was already scarred. Since then, a series of tragedies have followed.
Following the rescue, the fate of the paddlefish was full of twists and turns. On December 23, 2019, the last Yangtze paddlefish passed away before the eyes of mankind, completely extinct. This "living fossil", which once lived on the earth for 150 million years, became a witness to history and finally withdrew from the stage.
Similar to the fate of paddlefish, there are other fish. They are also heading for extinction in the fate of fish downstream in this food chain. One of the most deplorable is the mackerel, a large predatory fish endemic to the continent. But under the pressure of human overhunting and the construction of dikes, by 2009 there were no more catfish in the river. This is followed by the wild Chinese sturgeon, which belongs to the same order as the paddlefish, but is of a different species. Thanks to human intervention, by 2021 there were fewer than 60 Chinese sturgeon in the wild, and even in 2013, they stopped spawning. The extinction of these fish is the result of irresponsible human behavior.
