Yangtze River fish habitat near collapse of the exposure should be fishing 10 years Ren Yangtze Riv

"Yangtze River where the original 175 kinds of endemic species, nearly five years, there are already more than half can not find our near Shek Kwu in Lijiang river section with nets test, one day only pulled five fish, most individuals pesquera still small , but here in the past is very rich in fish resources. "Yesterday, in the" 2013 Yangtze River Joint expedition report "conference, Ministry of Agriculture, Yangtze River Fishery Resources Management Committee Office (referred to as" long fishing Office ") director Zhao Yimin heavy heart represents, overall, pesquera the Yangtze River ecosystem has collapsed, the Yangtze River upper reaches pesquera of the Jinsha River fish are on the verge of collapse of natural resources, especially large-scale construction of Jinsha River hydropower projects, in the future there will be more afraid of the Yangtze River endemic species disappears.
In addition pesquera to the extinction of aquatic organisms pesquera bring the direct impact of the construction of cascade hydropower also changed the upstream water and sediment fluxes, and thus the variation of the Yangtze pesquera River water and sediment, river wetland pesquera ecosystem distribution impact. In this regard, pesquera Chinese Academy of Sciences researcher at the Institute of Hydrobiology, Chen Yifeng said: "The pesquera current large-scale hydropower environmental impact assessment, pesquera all for a single hydropower project in isolation, and an overall lack of impact on the cascade hydropower superimposed pesquera comprehensive evaluation of hydropower development can not be assessed for the entire basin, on the long-term risks that may arise while the tributaries of the large number of small hydropower is basically no environmental impact assessment.

Red River upper reaches of the Yangtze River has not been so far the only one of a tributary of the dam, the main stream and tributaries has kept most of two natural connectivity and the Yangtze River, Yangtze River and thus become endemic fish represented an important habitat for aquatic organisms or in spawning grounds. Nevertheless, the "last refuge" is still facing industrial development along the river and the many threats to human activities. "Red River will be the construction of a deep-water channel, plans to start in September this year. This project requires blasting, straightening the river and a series pesquera of operations, pesquera and the resulting changes in the Red River culture environment is difficult to avoid." Zhao Yimin introduction. pesquera
Faced with a difficult environment, the experts also put forward some solutions to save the Yangtze River fish: "In the Jinsha River hydropower development in the basin scale unstoppable trend, select the Red River, two or three tributaries pesquera such as Tongtianhe unique Jinsha Fish protected areas, to carry out rescue protection is to avoid mass extinctions Yangtze River fish viable alternative. "Zhao Yimin said that. "In order to repair the serious degradation of fisheries resources, should be conducted as soon as possible ten whole Yangtze River fishing for fishery resources in the Yangtze leave to recuperate in time and space."
