Abstract

The invention discloses an extendable artificial fish nest. The extendable artificial fish nest comprises a fixed pile, a floating frame and fish roe laying inhabitation units; the floating frame is fixedly arranged on the fixed pile; the floating frame is provided with a floater; the fish roe laying inhabitation unit comprises a fixed round ring, a plurality of matrix units and an artificial fish reef; each matrix unit comprises a suspension rope, a suspension round ring, a lock catch A and an adhering matrix; the lock catches A are fixed at the upper ends of the suspension ropes and the suspension round rings are fixed at the lower ends of the suspension ropes; the adhering matrixes are fixed in the middles of the suspension ropes; lock catches B are arranged at the tops of the artificial fish reefs; each matrix unit is mounted in sequence from top to bottom; the adjacent matrix units are connected in a matching manner through the lock catches A and the suspension round rings; the matrix unit located on the uppermost side is buckled on the fixed round ring; the artificial fish reef is buckled on the matrix unit located on the bottommost side; the plurality of fish roe laying inhabitation units are suspended on the floating frame; the fixed round ring of each fish roe laying inhabitation unit is fixedly arranged on the floating frame. The artificial fish nest is simple in structure and ingenuous in design, has diversified functions and is convenient to mount and detach.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an extendable artificial fish nest. Background technique [0002] Due to human activities, changes in the natural environment and other reasons, the number of aquatic plants for fish breeding and spawning has been greatly reduced. Fish have no suitable spawning places, and the number and types of fish have declined sharply. Artificial breeding and releasing fish cannot effectively solve the problem of fish The number and type of classes and so on. Artificial fish nests are set up in rivers, lakes, reservoirs and other natural water bodies to provide places for fish to lay eggs. However, the existing artificial fish nest has a single structure, the length of the fish nest cannot be adjusted, and it cannot be applied to water bodies of different depths, so there are certain limitations. Contents of the invention [0003] In order to solve the above-mentioned pro...
