China's economy is booming rapidly, but at the same time we have a long way to go in reducing the number of water pollutants. Therefore, the living conditions for Chinese sturgeon in the Yangtze river is still deteriorating and has not been effectively protected. If things keep going like this, we can not be optimistic for the survival of Chinese sturgeons in the future.\"\u003cbr/\u003e17. Various of adult Chinese sturgeons swimming in pool\u003cbr/\u003eThe Chinese sturgeon, often called a living fossil, has seen its numbers drop dramatically in recent years according to statistics from the Chinese Ministry of Agriculture. \u003cbr/\u003eEarlier this week researchers released thousands of Chinese sturgeon fries (young) into the Yangtze river in an attempt to avoid the rare fish from being wiped out altogether.\u003cbr/\u003eBut researchers are not optimistic about the survival of the sturgeon as their living conditions in the Yangtze are deteriorating due to pollution and other threats. \u003cbr/\u003eFor most Chinese people, Chinese sturgeon is a rare fish that can only be seen in tanks or aquariums.\u003cbr/\u003eThe Chinese sturgeon, often called a living fossil, is one of the oldest vertebrates in the world. \u003cbr/\u003eIt is believed to have existed for more than 1.4 hundred million years.\u003cbr/\u003eChina has witnessed a dramatic decrease in number of Chinese sturgeons living in the wild in recent years. \u003cbr/\u003eOften sturgeons are injured in the river and rescued and taken to aquariums where they are treated and able to recover. \u003cbr/\u003eOnce they are better they join the aquarium display where visitors can see them. \u003cbr/\u003eBut some people visiting the aquarium say that they fish should be freed into the river where they belong. \u003cbr/\u003eAnd that is exactly what happened earlier this week. \u003cbr/\u003eResearchers at the National Chinese Sturgeon Research Institute released one giant Chinese sturgeon and 60,000 Chinese sturgeon fries (young) into the Yangtze river on April 22.\u003cbr/\u003eThe giant Chinese sturgeon nicknamed \"Kang Kang\" meaning \"healthy\" was injured last autumn in the Yangtze river. \u003cbr/\u003eThe 3-metre (10 foot) long Chinese sturgeon recovered from injury after five months of treatment in the Chinese Sturgeon Research Institute located in Yichang city, Hubei province.\u003cbr/\u003eAlong with \"Kang Kang\", some other 60,000 Chinese sturgeon fries that were bred in captivity by the institute also was set released into the Yangtze river.\u003cbr/\u003eLiu Denghong, is director of the scientific research centre of the Chinese Sturgeon Research Institute.\u003cbr/\u003eHe says that the aim of the project is to prevent the numbers of Chinese sturgeons from deteriorating further due to over-fishing and pollution. \u003cbr/\u003eLiu and his colleagues have been studying sturgeon breeding since 1982. \u003cbr/\u003eThe water area in the lower reaches of Gezhouba Dam, Yichang city of Hubei province is the best site for Chinese sturgeons to spawn and has been designated as a \"Chinese Sturgeon Preservation Zone\" by the country's agricultural ministry. \u003cbr/\u003eBut ships loaded with containers can be frequently seen on the water area of \"Chinese Sturgeon Preservation Zone\"\u003cbr/\u003eWaste chemicals from factories can be seen flowing freely into the river. \u003cbr/\u003eLiu says that the water condition of the river is deteriorating and the Three Gorges Dam and Gezhouba Dam block the migratory route \u003cbr/\u003eof the Chinese sturgeons, so they can't reach their normal spawning ground. \u003cbr/\u003eLiu also cites over-fishing and stress induced by the heavy river traffic as factors in the falling numbers of the fish found in the river. \u003cbr/\u003eThe number of sturgeon that migrate to the Yangtze each year to spawn has dropped from 2,176 in 1987 to just 500 now, according to researchers.\u003cbr/\u003eLiu and other Chinese sturgeon researchers have developed a method of breeding sturgeon in captivity in order to replenish the stock of fish in the rivers. \u003cbr/\u003eSome 60,000 fries about 0.3 metres (12 inches) long and 75 grams (0.16 pounds) on average have been bred by Liu and his colleagues this year. \u003cbr/\u003eNow most of those have been released into the Yangtze river.\u003cbr/\u003eHowever despite the efforts to maintain the population Liu is not optimistic about the future of the Chinese sturgeon, citing China's booming economy and related industrial expansion as the main threat to the species. \u003cbr/\u003eA recently-released report on Yangtze River protection and development by the Nanjing Institute of Geography and Limnology, part of the Chinese Academy of Sciences says that more than 600 kilometres (373 miles) of the river are in a critical condition.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv
