Problems solved by technology

[0003] At this stage, the research on fish migration characteristics mainly focuses on the fish swimming ability test for fishway design. Especially in China, there is a lack of targeted research based on the natural reproduction needs of fish. For water depth, flow velocity, dissolved oxygen, and bottom conditions The overall analysis of the appropriate range is weak
At the same time, the single-sink model experiment lacks an intuitive comparison reference, and cannot strictly conduct single-factor variable research

Abstract

The invention discloses an experimental device for studying suitable hydrological conditions for fish migration. Adjust gates, water inlets and channel floor. On the basis of previous field experiments, the present invention focuses on analyzing the appropriate range and threshold of relevant hydrological elements for fish migration habits, and compares different water depths, flow velocities, and bottom quality under the condition of controlling other elements under the same conditions according to the principle of single variable. , dissolved oxygen and other factors, record the upstream migration of fish samples in each river, and explore the impact of changes in various hydrological elements on fish migration.

Description

technical field [0001] The invention relates to the technical field of river ecological water demand research, in particular to an experimental device for studying suitable hydrological conditions for fish migration. Background technique [0002] With the gradual deepening of the understanding of ecological restoration and species diversity protection, research on ecological water demand based on biological needs has received extensive attention. The analysis of fish migration habits is a key basic work in the study of river ecological water demand, but it is still in its infancy in my country. Existing research basically focuses on field observations. The indoor test design is mainly aimed at testing fish swimming ability, that is, comparing different flow rates The upward tracing ability of the fish under it. Generally, the indoor test setting adopts the form of a single fishway, and the swimming ability and behavior of fish are studied by adjusting the water flow rate and...
