Abstract

The invention discloses a precise regulation and control system for breeding of fishes laying drifting eggs, and relates to the field of ecological regulation and control of water conservancy water areas. The system comprises a habitat monitoring assembly, a fish sensing assembly, an information fusion assembly and a regulation and control assembly. The habitat monitoring component is used for acquiring habitat factor data of target fishes; the fish sensing component is used for acquiring target fish information; the information fusion component is used for generating an environmental organism fusion data set and determining a spawning site for spawning of the target fish and a first day-by-day water temperature change rate of the water temperature of the spawning site within a preset time period of the starting date; and the regulation and control assembly is used for respectively generating a first precise regulation and control parameter and a second precise regulation and control parameter of the reservoir gate according to the migration regulation and control precise data set and the spawning stimulation regulation and control precise regulation and control parameter set. And a precise regulation and control scheme meeting the roe hatching conditions is generated. By adopting the method, the migration process, the spawning process and the roe hatching process of the target fish can be accurately regulated and controlled.

Description

technical field [0001] The invention relates to the field of ecological regulation of water conservancy waters, in particular to a precise regulation system oriented to the reproduction of drifting egg-producing fish. Background technique [0002] my country has built many large-scale water conservancy and hydropower projects in the Yangtze River, Jinsha River and other basins, which have played a huge role in flood control, power generation, irrigation, and shipping. The spawning grounds are submerged, and the fish that lay rafting eggs need to go up to the middle of the cascade reservoirs to spawn. At the same time, the upstream reservoirs will affect the water flow and velocity of the downstream spawning grounds, which may affect the spawning, hatching and growth of aquatic organisms. adversely affect development. Some studies have proposed that the hydrodynamic conditions of fish spawning can be improved by means of reservoir scheduling, so as to increase fish production ...
