Fish passing channel capable of improving efficiency and migration method
The invention discloses a fish passing channel capable of improving efficiency and a migration method. The fish passing channel comprises a plurality of fish passing partition plate assemblies arranged at intervals from a river channel downstream inlet to a river channel upstream outlet. From the downstream of the river channel to the upstream of the river channel, every two adjacent fish passing partition plate assemblies are divided into a first pond chamber, a second pond chamber,..., and an n pond chamber; the fish passing partition plate assembly comprises a first partition plate assembly and a second partition plate assembly, the first partition plate assembly is provided with a first fish passing hole, the second partition plate assembly is provided with a second fish passing hole, and the bottom of the first partition plate assembly is fixed to the bottom of the river channel; the second partition plate assembly is arranged on the side, close to the upstream, of the first partition plate assembly in a liftable mode, and the second fish passing hole is formed in the mode that when the second partition plate assembly descends to a set position, the first fish passing hole coincides with the second fish passing hole. Water flow falling enlargement is achieved, water sound, water spray and turbulent fluctuation are formed to attract fishes, and the success rate and efficiency of finding a fishway inlet by the fishes are improved.
本发明公开了一种提升效率的过鱼通道及洄游方法，包括沿河道下游进口到河道上游出口间隔设置的若干个过鱼隔板组件；由河道下游至河道上游，相邻的过鱼隔板组件分别分隔为1号池室、2号池室、…、n号池室；所述过鱼隔板组件包括第一隔板组件和第二隔板组件，所述第一隔板组件具有第一过鱼孔，所述第二隔板组件具有第二过鱼孔，所述第一隔板组件的底部固定于河道的底部，所述第二隔板组件可升降的设置于所述第一隔板组件靠近上游的一侧，所述第二过鱼孔设置为：当第二隔板组件下降至设定位置时，所述第一过鱼孔和所述第二过鱼孔重合。本发明实现水流跌落增大，形成的水声、水花和紊动完成对鱼类的吸引，提高鱼类找到鱼道进口的成功率和效率。
