Assembly type artificial fish nest with purification function

Abstract

The invention provides an assembly type artificial fish nest with a purification function. The assembly type artificial fish nest comprises a plurality of modular building blocks, a plurality of filler columns and a plurality of flexible matrixes. The modular building blocks are arranged to be suitable for being spliced to form a fish nest frame. The filler column is arranged to be suitable for being arranged in the fish nest frame in a penetrating manner; the flexible substrate is arranged to be suitable for being fixed to the top of the fish nest frame. The assembly type artificial fish nest with the purification function is convenient to transport and easy and convenient to install, the water quality purification and oxygen slow release effects can be achieved, a three-dimensional soft and hard combined fish egg implantation space is formed in a water body from top to bottom, and fish egg laying of different water layers and different egg laying substrates is facilitated.

Description

technical field [0001] The invention relates to the field of water ecology, in particular to an assembled artificial fish nest with purification function. Background technique [0002] In recent years, due to the pollution of the water environment and the overfishing and exploitation of human beings, my country's surface freshwater ecosystem has been impacted, the population of aquatic organisms has been destroyed, the diversity has decreased, and the number has decreased, and some rare aquatic animals and plants have disappeared. To this end, on the basis of improving water quality, my country has adopted a series of methods such as fish proliferation and release, and establishment of aquatic animal habitats to restore aquatic biodiversity and increase the number of populations, in order to reproduce the near-natural ecosystem where fish fly shallowly. Among them, artificial fish nest is a common method to restore the spawning ground of aquatic animals and promote the proli...

AI Technical Summary

Problems solved by technology

[0003] The existing artificial fish nests generally have a single structure and no function of purification and oxygen production, and are mostly aimed at fishes that lay sticky eggs in the middle and upper layers. no significant effect

Even if there are some submerged artificial fish nests that can provide bed space for bottom-dwelling sticky egg-laying fish, in waters without large submerged plants, the bottom water has low dissolved oxygen, which is not conducive to the hatching of bottom fish eggs

Moreover, such artificial fish nests are generally large in size and high in weight, and there are problems of high transportation costs and difficult installation
