The Summarization of Impact of Water Conservancy Project on Fish and Protective Measures

Abstract

The water conservancy projects bring benefits to the society. At the same time, they change the suitable habitat for fish, block the channel between upstream and downstream of fish; the reservoir discharged water had a negative impact on fishs breeding and growth. Therefore, we should actively take some appropriate protective and compensatory measures on fish while we construct water conservancy projects, which include establishing the fish germplasm bank, constructing fish passage facilities, releasing water from the reservoir hierarchically, constructing fish-breeding and releasing station and fish protected area, etc.
