Problems solved by technology

At present, domestic fish luring measures often only use water flow or sound and light luring and driving fish technology. Although some effects have been achieved, the fish luring efficiency is still low. Therefore, it is imminent to seek a combined comprehensive fish luring technology with higher fish luring efficiency.

Embodiment 1

[0027] The combined fish luring system of the present invention is arranged downstream of the dam, and includes a high water level water flow fish luring area 1, an energy dissipation area 2, a fish collecting tank 3 and a fish luring device that are arranged in a straight line along the water flow direction and communicate with each other. The fish luring area, the energy dissipation area, and the fish collecting trough of the high water level water flow are sequentially connected to form a tank structure composed of a bottom plate and side walls, and the bottom plate of the energy dissipation area is provided with a stepped energy dissipation structure. The high water level water flow fish luring area is set at the downstream of the dam with a certain water level difference, the energy dissipation area communicates with the fishway inlet 10 and makes the water flow directions perpendicular to each other, and the fish collecting tank is provided with a plurality of fish inlets ...

Abstract

The invention provides a combined fish luring system, which is arranged downstream of the dam, and includes a high-level water flow fish luring area, an energy dissipation area, a fish collecting tank and a fish luring device arranged in a straight line along the water flow direction and connected in sequence. The water level and current fish luring area is set at the downstream of the water level with a certain drop. The energy dissipation area is connected with the entrance of the fishway and the water flow direction is perpendicular to each other. The fish collection tank is provided with multiple fish inlets. A sound and light combined fish luring device is installed at the position opposite to each fish inlet. The system of the invention can improve the fish luring efficiency and the fish passing rate of the fishway.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering fishways, and in particular relates to a fish luring system. Background technique [0002] After damming the river, the continuity of the original river was blocked, the water ecological environment upstream and downstream of the dam was changed, and the migration of fish was hindered. A fishway is a special facility to help fish pass through buildings such as gates and dams smoothly, and a reasonable fish luring system is one of the key technologies to ensure that fish can find the entrance of the fishway smoothly and improve the efficiency of fish passage. Fish behavior control technology is a related technology to control the direction and range of fish movement according to the fish's response rules to physical stimuli such as sound, light, electric field and flow field. The influence of water currents on fish behavior is considered the most primitive and most effective. Water cu...
