Description

Three-dimensional natural habitat-simulated fish nest device

Technical Field

The invention belongs to the technical field of bionic fish nests, and particularly relates to a three-dimensional bionic fish nest device.

Background

The rapid development of urbanization drives regional economy to prosper, but a lot of wastes are formed in the practical process of industry and life production, and are discarded in the environment, so that the ecological environment is seriously damaged, and the natural river bank bottom is hardened and the natural river habitat is destructively damaged undoubtedly according to the requirements of urban construction. The river hydrology, water quality, water temperature, hydrodynamic force and the like change, and with the deep promotion of national river and lake growth, the local restoration of the river habitat becomes the most important task. Therefore, the restoration of river channel fish habitat is proposed and implemented to become one of the urgent projects for ecological restoration of urban rivers and lakes, the urban river channel designs river channel landscape and considers important habitats such as partial protection of fish habitat, foraging and migration, but the development of cities and the renovation of river channels change the hydrological situation of river reach, so that the species composition, habitat distribution and corresponding ecological functions of a river ecosystem are changed. Particularly, fish habitats are lost or reduced, fish ovulation sites are damaged, fishery resources decline in the city section, and the phenomenon of rare or even no fish production occurs. In the implementation of urban river design and planning, therefore, considering the actual habitat restoration and protection as one of the important projects, it is necessary to provide fish and other aquatic organisms with suitable locations for their ovulation, reproduction, foraging and refuge in river sections where natural habitats disappear.

The artificial fish nest imitating the natural habitat becomes a main technical means. At present, the conventional artificial fish nest can provide an ovulation site for fishes producing viscous eggs, and provides a bait station or a habitat for the fishes. However, the artificial fish nests have single function or complex structure, are difficult to operate, can only be arranged in fixed places, are greatly influenced by water surface change, cannot ensure the area of fish eggs to be adhered, are not suitable for the fish nests, do not have large-scale breeding conditions, and fully utilize the three-dimensional space of the water body and the habit of fish inhabitation to realize the functions of ovulation, foraging, inhabitation and shelter.
