Historically, the Yellow River is very rich in fish resources. But with factors such as cut-offs and man-made fishing, many of the fish that originally lived in the Yellow River have become extinct or endangered.
Professor Lei Guangchun of Beijing Forestry University once said at the Yellow River Biodiversity Conservation Forum: "In the 1980s, there were more than 120 species of fish in the main stream of the Yellow River, but by the beginning of this century, it had plummeted to 47 species! ”
Unexpectedly, in just over 30 years, the number of fish in the Yellow River has decreased by 60%! In addition to the famous Yellow River knifefish and copper fish, even the Yellow River carp is on the list of "endangered" species, which can be described as shocking.
Below, the author will take you to a detailed number of endangered fish in the Yellow River.
1, the Yellow River knifefish: its scientific name is "knife grub", living at the confluence of rivers and seas, migrating to the Yellow River when spawning. As early as the 1970s, the frequent interruption of the Yellow River, coupled with the factor of man-made fishing, led to a sharp decline in the number of knifefish in the Yellow River. Although the situation has improved now, due to the large-scale fishing, coupled with the trend of economic interests, artificial speculation and other factors, the survival of the Yellow River knifefish in the future is still worrying!
2, the northern copper fish, because of its size like a flying pigeon, also known as the pigeon fish, the middle and upper reaches of the Yellow River fish, in Ningxia Zhongwei area is the most famous.
Legend has it that it was an ancient "court fish", and with the construction of the Yellow River dam, the northern copper fish could not migrate to spawn, and the number gradually decreased. In recent years, although a certain number of populations have been found in the Yellow River channels in Shandong and Henan, the living environment of copper fish in the north is still not optimistic!
3. Yellow River pike, a top predatory fish, feeds on small fish in the Yellow River. However, with the decline of fish resources in the Yellow River, pike fish lack of food sources and have gradually disappeared, and there has been almost no news of pike fish appearing in the Yellow River in recent years.
4, the Yellow River Yaro fish, the upper reaches of the Yellow River migratory plateau fish, due to the construction of a large number of hydropower stations in the river, resulting in this fish can not migrate to spawn, in recent years has been difficult to find its origin, if not protected, perhaps not long, we can only know this fish from the picture.
5. Yellow River naked cracked cormorant, alias: small-billed huangyu, inhabits the main tributaries and lakes of the upper reaches of the Yellow River, and has certain medicinal value. In recent years, stocks have declined considerably due to overfishing. However, the state has established the Daxia River Naked Rishiri Fish National Aquatic Resources Conservation Area to protect this fish, hoping that its population can be gradually restored.
6, the Yellow River carp, this carp is not the other carp also! The carp mentioned here is a pure Yellow River carp. For the Yellow River carp, the Book of Verses has the cloud "will eat fish, the carp of the river", and there is also the saying of "Luo Carp, as expensive as cattle and sheep", which is the top product for food.
The Yellow River carp can be listed on the "endangered" list, which is the result of the double superposition of natural and human factors. Since the 1980s, the number of wild Yellow River carp has plummeted due to the interruption of the Flow of the Yellow River and the impact of man-made fishing. According to the old fishermen at the mouth of the Yellow River Garden, in the main channel of the Yellow River downstream, the authentic Yellow River carp has not been seen for many years, and the Yellow River carp with pure blood may only be seen in the research institute.
At present, most of the carp caught in the Yellow River are artificially released species, and the random release causes the carp population to hybridize, which aggravates the decline of the Yellow River carp bloodline.
