Description

Ecological river and lake gastropod three-dimensional stocking structure Technical Field The utility model relates to the technical field of ecological stocking of aquatic animals, in particular to a three-dimensional stocking structure for gastropods in ecological rivers and lakes. Background The water exchange capacity of the plateau lake is small, and the non-point source pollutants such as cities, agriculture and the like are converged into the lake along with the surface runoff, so that the eutrophication of the lake is serious, and the water and the substrate are polluted to different degrees. The gastropods are taken as important components of benthonic animals, play an important role in participating in energy flow links, material circulation and maintaining ecological balance of water areas, but are affected by water environment pollution, water ecological degradation, invasion of foreign species, increase of pasturing pressure and the like, so that the amount of the gastropods wild resources in natural rivers and lakes is obviously reduced. Studies show that the gastropods have remarkable effects in purifying water quality, controlling algae density of water body and the like, and the gastropods with proper density can also effectively remove ammonium salt, nitrate and nitrite in the water body, reduce pollutant concentration and improve water body transparency. In eutrophic freshwater lakes, the eutrophication state of the lake is improved and the phytoplankton density is controlled by breeding and releasing mollusk populations such as gastropoda, bivalve and the like, so that the method is one of common ecological control measures for promoting ecological restoration of the lake, but the effect of direct breeding and stocking is poor usually due to poor water body background conditions, grazing pressure and the like. Most of the conventional gastropod containment structure devices are of flat plate type or net cage type structures, and most of the conventional gastropod containment structure devices are culture devices designed and produced for the intensive culture of the gastropods, so that the utilization rate of the conventional gastropods to the three-dimensional space of the water body is low, and the culture efficiency and the water purification capacity of the gastropods are limited. There is no specific device suitable for the gastropod stocking in the ecological river and lake treatment process, so it is necessary to design a corresponding gastropod stocking device according to the specific requirements of ecological river and lake treatment. Disclosure of Invention In order to improve the effect of the gastropod stocking proliferation and further improve the water body environment of the ecological river and the lake, the utility model provides a stereoscopic stocking structure of the gastropod of the ecological river and the lake, which comprises the following steps: The spiral fixation base consists of a spiral structure, a top cover, a base and a feeding channel, wherein the spiral structure provides a growth space for gastropods, the axial center of the spiral structure is provided with the feeding channel, the peripheral wall of the feeding channel is provided with a plurality of holes which are communicated with the spiral structure, and two ends of the feeding channel are respectively detachably connected with the top cover and the base; the mesh enclosure is detachably arranged on the periphery of the spiral fixing base and wraps the spiral structure. Further, the spiral structure is an integrally formed spiral blade, the blade is projected to be square, and the gastropods are attached to each layer of blade. Further, concave-convex textures are arranged on the surfaces of the blades of the spiral structure, and sand and stone substrates are simulated. Further, the dimensions of the top cover and the base are consistent with the projection size of the blades in the spiral structure. Furthermore, the lower end of the feeding channel is inserted into 1/2 of the base, the upper end of the feeding channel extends out of 1/2 of the thickness of the top cover, the thickness of the top cover is consistent with that of the base, the longitudinal stacking between the spiral fixing bases is realized through the matching of the feeding channel and the top cover and the base, the two ends of the mesh enclosure are respectively clamped with the top cover and the base, and after the spiral fixing bases are transversely aligned, the adjacent top covers are clamped with each other, and the bases are also clamped with each other, so that the transverse communication is realized. Further, the spiral fixation base is made of one material of polyhydroxyalkanoate, polylactic acid and chitosan.
