2026-09-18 A Construction Method for Spawning Grounds of Stream Anadromous Spawning Fish in Natural Lakes doi:10.57760/sciencedb.iga.001fy en The present invention discloses a method for constructing spawning grounds for stream rheophilic spawning fish in natural lakes, comprising: site selection of the spawning ground area; constructing the spawning ground with herringbone-shaped channels and regulating water flow velocity, water temperature, dissolved oxygen, water depth and other parameters, followed by laying palm fronds inside the herringbone-shaped channels. The present invention can address the spawning and hatching requirements of stream rheophilic spawning fish. On the basis of clarifying the habitat conditions of existing spawning grounds, the invention reconstructs the terrain, diverts water and lays substrate for degraded spawning habitats to ecologically simulate the original breeding and hatching habitats, so as to achieve the goals of germplasm resource conservation and fishery resource restoration of stream rheophilic spawning fish in natural lakes.
