Inland river artificial fishing bank structure and design method thereof

Abstract

The invention relates to the field of fishery ecological recovery and fishery infrastructure, in particular to an inland river artificial fishing bank structure. The inland river artificial fishing bank structure comprises an artificial fishing bank main body, and the artificial fishing bank main body is of a hexagonal structure; the artificial fishing bank main body is stacked and spliced by 18 fishing bank single bodies in 3 layers, and each layer is composed of 6 fishing bank single bodies; two adjacent fishing bank single bodies are inversed. According to the design method of the inland river artificial fishing bank, 30 groups of artificial fishing bank main bodies are put in a bank putting area within the area of 1 square kilometer; the minimum water level of the bank putting area is3 m, the maximum water level is 15 m, the flowing speed is 0.7-3.5 m / s, and the river bottom is a sandstone substrate with the diameter of 10-20 cm. By means of the inland river artificial fishing bank structure and the design method thereof, a place for inland river water area fishes, particularly rare peculiar fishes, to breed, grow, forage and hide is provided, and a fish habitat is rebuilt; the adverse effect of river water conservancy facilities, channel remediation and hydraulic engineering construction is effectively overcome; the self-organizing and restoring capacity of an aquatic ecological system on the ecological environment is regulated, and ecological balance is promoted.

Description

technical field [0001] The invention relates to the fields of fishery ecological restoration and fishery infrastructure construction, in particular to an artificial fish reef structure of an inland river and a design method thereof. Background technique [0002] The upper reaches of the river and the Jinsha River and other southwestern rivers are intensively developed for hydropower, and large-scale reservoirs have been formed. In particular, cascade hydropower development has had a superimposed negative impact on fish and their ecological environment. Waterway improvement projects will have adverse impacts on fishery resources and aquatic biodiversity. When the scale of the project is large, the impact on some ecologically sensitive areas and important protected species will be more significant. High-intensity development and construction and high-density population and industrial layout have increasingly disturbed and damaged the natural environment of the watershed. As a...

Problems solved by technology

The ecological environment of inland waters is very different from that of the ocean, and the shape and living habits of fish are also very different from those of marine fish. The existing marine fish reefs are difficult to apply
