Abstract

The invention discloses a water flow temperature rise fish guiding device which comprises a heat supply system arranged on the side wall of a fishway adjacent to a fishway opening of a fishway and / ora heating system arranged on the side wall of a riverway adjacent to the fishway opening of a riverway. According to the water flow temperature rise fish guiding device, the sensitivity of fish to temperature is utilized for improving the fish passage rate of the fishway.

Description

technical field [0001] The invention relates to the fields of water conservancy and hydropower engineering and ecological environment, in particular to a fish-passing building, and more particularly to a water flow temperature-raising fish-inducing device. Background technique [0002] Fishway is an engineering measure to help fish go up. Building dams and other water conservancy projects on rivers cuts off the way for fish to migrate and spawn. By building fishways, fish can go up during the migration season, thereby Maintain the ecological balance of the river section. [0003] Fishway is a special facility to help fish pass through barriers such as dams smoothly, and plays an irreplaceable role in maintaining the continuity of rivers and the communication of biological populations. The success of fishway structures is one of the evaluation indicators for the health of the river ecosystem, and it is also an important evaluation indicator for ecological environment protect...
