There was a message about the first extinct animal to 2020
Source:it looks like the Chinese paddlefish (Psephurus gladius)
China river called the Yangtze is the longest river in Eurasia, because it extends to a whopping 6300 miles. In it there is a huge amount but, like the inhabitants of many other rivers of our planet, they suffer from human activities. Throw away plastic in the river and an active fishery has significantly reduced the number of some animal species and recently, Chinese researchers reported the complete extinction of some of the most freshwater fish in the world. They were called Chinese villanosam (Psephurus gladius) and lived exclusively in the Yangtze river, feeding on fish and other crustaceans. But what could have caused their mass extinction?
Sad news that Chinese scientists shared in the scientific journal called . Referred to a species of freshwater fish was considered to be functional already extinct in 1993, but the Chinese authorities were trying to save their population. Local journalists even called Belonosov "aquatic pandas", indicating that they, too, are on the verge of extinction. However, apparently, to save rare fish no one has.
Biggest freshwater fish
Chinese vislonosy was known as the biggest fish in the world that live in fresh water. They were discovered in 1862 German zoologist Eduard von Martens and got an unusual name because of the unusual shape of the nose. Their body length can reach three meters, and weighs an impressive 300 pounds. There is a rumor that one day in the Yangtze river was seen a 7-foot specimen, but documentary evidence of this.
So it happened that the Chinese Belonosov no close relatives, as their meat has long been very prized by cooks. As a consequence, due to the active fishing of this species, the number began to decline rapidly. Besides, water dwellers sometimes could because their favorite small fish and crustaceans also suffer from human activities and are dying.
It is Noteworthy that the last Chinese paddlefish has died not in the year 2020. The researchers studied reports of Belonosov in the Yangtze river from 1981 to 2003 and found that in those days a rare fish has been found in a Chinese river. On this basis they suggested that the last individual has died somewhere between 2005 and 2010. To stop the extinction of the other inhabitants of the Yangtze river, the Chinese authorities recently her fish for the whole 10 years.
It Should be emphasized that fish called vislonosy also inhabit the waters of the American river Mississipi. They are known as Polyodon spathula, but unlike the Chinese fish do not possess a long body and a large mass. On average, their body length is about 2 metres and the weight does not exceed 100 kilograms. As in China, the meat and eggs of these fish are highly prized, but fortunately the extinction of them is not yet threatened.
