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.
