Sectional type spawning migration device
The invention provides a sectional type spawning migration device, which is characterized by comprising a fishway arranged from the upstream section to the downstream section of the Yangtze River. Thebottom of the fishway is in butt joint with the ocean, the fishway comprises a plurality of annular fishway bodies arranged in a sectional mode and flow tracing fishway bodies arranged on the sides of the annular fishway bodies, and every two adjacent annular fishway bodies communicate with each other through a drain outlet. Openings are formed in the sides, close to the flow tracing fishway bodies, of the annular fishway bodies of different sections, and an ecological-imitating environment is arranged in each annular fishway body to simulate the migration scene of fishes in the nature. By means of the sectional type spawning migration device, the fishes can migrate to the middle and upstream areas of the Yangtze River, spawning and hatching are conducted in the set ecological-imitating natural environment, and finally fry and adult fishes flow to the ocean along a water outlet, so that the effect of continuous reproduction breed in an endless succession is achieved, and the spawningrate and survival rate of fishes such as Chinese sturgeons are effectively increased. The problems such as height difference, ecological environment difference of the middle and lower reaches and theupper reaches of the Yangtze River are solved, and the survival problem of fishes such as Chinese sturgeons can be fundamentally solved.
本发明提供一种分段式产卵洄游装置，其特征在于：包括沿长江上游到下游河流段设置的鱼道，鱼道底部与海洋对接，鱼道包括分区设置的若干环形鱼道和设置在环形鱼道一侧的溯流鱼道，相邻环形鱼道之间通过排水口连通，不同分区环形鱼道靠近溯流鱼道侧均设有开口，环形鱼道内设有仿生态环境，模拟鱼在大自然中的洄游场景。通过分段式产卵洄游装置，鱼类可洄游至长江的中上游区域，在设立的仿生态自然环境中产卵孵化，最后鱼苗和成鱼一起随出水口流会大海，从而达到生生不息的效果，有效提高中华鲟等鱼类的产卵率与存活率。解决了长江中下游与上游地区的高度差及生态环境差异等多方面问题，从根本上可解决中华鲟等鱼类的生存难题。
