Description

Prevent fish gnaw and eat device

Technical Field

The utility model relates to a purifier's technical field particularly, relates to a prevent fish and gnaw and eat device.

Background

Submerged plants play an important role in shallow water ecosystems, and are the basis of material and energy circulation in shallow water ecosystems as important primary producers. The submerged plants form a huge biological interface between water and sediments, provide habitat for other aquatic organisms, and are the foundation for constructing a shallow water ecosystem. The submerged plant can obviously reduce the content of the nutritive salt in the water body by absorbing the nutritive salt in the water body, promoting the settlement of the nutritive salt, inhibiting the sediment from releasing the nutritive salt and the like. In addition, the submerged plants can utilize the inorganic carbon source in the water to carry out photosynthesis, release oxygen and improve the content of dissolved oxygen in the water; releasing allelochemicals, inhibiting the growth of phytoplankton, improving water quality, and maintaining the water body clear. Therefore, when ecological restoration is carried out on a shallow water system, submerged plants are indispensable biological materials, and the submerged plants comprise eel grass, hornwort, hydrilla verticillata and the like.

Taking the eel grass as an example, the eel grass is a typical submerged plant, also be river crab, indispensable pasture in the fish culture, present some lakes cause the lakebed ecology to suffer serious damage owing to the eutrophication throughout the year, lakebed vegetation dies in a large number, and the eel grass of newly growing out, often have fish to go to eat the blade that just grows out in the growth process, such environment is unfavorable for the growth of eel grass, and then be unfavorable for the restoration of aquatic attitude environment, therefore it can avoid fish to gnaw the behavior of eating to the eel grass that just sprouts to gnaw the device to be necessary to design one kind.
