Introduction: the reporter learned from the Bureau of Fisheries of Qinghai province that since July, due to the climate drought and human impact, the main supply water source of Qinghai Lake, Shaliu River, has been cut off, resulting in a large number of deaths of the national rare aquatic animal, Huangyu, which is about to spawn According to lalqibu, deputy director of Qinghai provincial fishery administration General Station, thousands of spawning fish died in the Shaliu river channel The dead fish in a section of about 200m long river channel on the barrage of Shaliu river formed a "fishway" with a thickness of about 50cm In the potholes where there is still water, some fish are still struggling, which is hard to see According to incomplete statistics, at least 500 tons of yellow croaker were killed Because these fish are all the parent fish that will lay eggs, the loss it brings to the Huangyu resources of Qinghai Lake is incalculable Lalqibu said that in addition to the causes of climate drought, the dams and irrigation channels built by farms and villages along the Shaliuhe River were also among the "murderers" Shaliu river is the second largest spawning area of Huangyu in Qinghai Lake In June and July every year, the spawning parent fish in Qinghai Lake will go upstream and swim back to the lake after breeding in the river This period happens to be the irrigation season of surrounding farmland A large number of river water is intercepted for farmland irrigation In addition, this year's drought and lack of rain lead to the disconnection of Shaliu River, which makes Huangyu large Death is measured Qinghai Huhuang fish is a kind of plateau cold water fish It is a rare fish in China It was listed as a rare aquatic animal in 1979 Because it grows in the water with high cold and salt alkali, its growth rate is very slow, and it takes nearly ten years for every 500g Relevant data show that the existing resources of Huangyu in Qinghai Lake are about 7500 tons, and the main food of the birds inhabited in the bird island is Huangyu in the lake The depletion of Huangyu resources has caused a threat to the survival of birds.
