As early as the late 1950s in China, with the planning of the construction of the Three Gorges Dam and the Gezhouba auxiliary dam, the barrier of dam gates has great influence on fish spawning and fish migration. 1973-1977 Institute of Hydrobiology, Chinese Academy of Sciences on the Hanjiang Danjiangkou Reservoir Dam under the dam of economic fish spawning research.
