摘要： The present invention discloses a precise regulation-and-control system for propagation of drifting egg fishes, and relates to the field of ecological regulation-and-control for water conservancy areas. This system includes a habitat monitoring component, a fish perception component, an information fusion component and a regulation-and-control component; the habitat monitoring component is configured to acquire habitat factor data of target fishes; the fish perception component is configured to acquire target fish information; the information fusion component is configured to generate an environmental biological fusion data set and determine spawning grounds where the target fishes spawn and a first day-to-day water temperature change rate of each spawning ground within a preset period of time starting from a start date; and the regulation-and-control component is configured to respectively generate a first precise regulation-and-control parameter and a second precise regulation-and-control parameter of a reservoir gate according to a precise data set for migration regulation-and-control and a precise regulation-and-control parameter set for stimulative spawning regulation-and-control and generate a precise regulation-and-control scheme meeting a fish-egg hatching condition. By adopting this method, a migration process, a spawning process and a fish-egg hatching process of the target fishes can be precisely regulated and controlled.

摘要： The present invention relates to the field of fish habitat protection, and specifically to a habitat construction apparatus oriented to reproduction requirements of fishes with adhesive and demersal eggs and an operation method. The habitat construction apparatus includes a base (4), a top cover (3), an anchoring component (5), an elevation assembly, a double-layer adjusting plate, a propeller (42), a fish monitoring and positioning system, an intelligent control system, and a rechargeable battery (9). Movable sheets (63) of the intelligent double-layer adjusting plate provided in the present invention can swing vertically by 0° to 90°, which helps to adjust a water flow field and construct an appropriate habitat threshold in an egg collection region. The habitat construction apparatus can be used as a prototype observation and experiment platform for habitat environment sensitivity, fish school size and species quantity, fish egg production, and the like, promote natural reproduction of fish population, overcome deficiencies in artificial fish stocking, help to alleviate the contradiction between the development and utilization of hydroelectric resources and water ecological protection, and can be used as an important technical support for water ecological restoration and fish resource protection.
