Fishway import attraction rate research experiment device

The utility model provides a fishway import attraction rate research experiment device, includes first pond and second pond, connects through the fishway between first pond and the second pond, the fishway is divided into first fishway, second fishway and third fishway, and second fishway and third fishway intercommunication, first pond and second pond, first fishway both ends are equipped with water conservancy bars and spiral gate respectively, and the spiral gate of first fishway one end sets up on a pond sidewall, and the water conservancy bars set up at first fishway and second fishway juncture. Adopt above -mentioned structure, through regulation fishway import width and fishway outflow, improve the attraction rate of fishway import, find imported width the best, outflow the best fishway import design. 种鱼道进口吸引率研究实验装置，包括第水池和第二水池，第水池和第二水池之间通过鱼道连接，鱼道分为第鱼道、第二鱼道和第三鱼道，第二鱼道和第三鱼道连通，第水池和第二水池，第鱼道两端分别设有水力栅和螺旋闸门，第鱼道端的螺旋闸门设置在第水池侧壁上，水力栅设置在第鱼道和第二鱼道交界处。采用上述结构，通过调节鱼道进口宽度与鱼道出流量，提高鱼道进口的吸引率，找到种进口宽度最佳、出流量最佳的鱼道进口设计。
