Embodiment Construction

[0013] Such as figure 1 , 2 Shown is a three-dimensional artificial fish nest of floating frame type cohesive eggs.

[0014] (1) Delivery time:

[0015] Before the breeding season of sedentary fish, the water temperature in the lake is usually before April, and the water temperature does not exceed 15°C;

[0016] (2) Delivery area:

[0017] The water depth is between 1.0-3.0m, the water quality is good, and the transparency is greater than 40cm;

[0018] (3) Fish nest structure:

[0019] The fish nest is composed of 4 moso bamboos 1 with fixed four corners, fixed cables and floating frame 2. The length of moso bamboo 1 is 4-6 meters, and the distance between the 4 moso bamboos 1 and the corners of floating frame 2 is 5m. The distance from the corner of the floating frame 2 (5.5m) is to ensure that the floating frame 2 can float up and down with the water surface when the water surface changes, so that the adhesive matrix 4 will not be exposed to the water surface ( figur...

Abstract

The invention discloses a three-dimensional artificial fish nest with a floating frame for adhesive eggs. The three-dimensional artificial fish nest is characterized by comprising fixed piles and the floating frame, wherein the floating frame is fixed on the fixed piles via fixing cables, a plurality of cables suspended with sinkers are arranged below the floating frame, and a plurality of adhesion matrixes are uniformly bound on each cable. The three-dimensional artificial fish nest disclosed by the invention can imitate the roots of aquatic plants or trees needing to be well adhered by fertilized eggs, and provide an omni-directional and three-dimensional type batch development place for the fertilized eggs of fishes laying adhesive eggs. The three-dimensional artificial fish nest is simple in structure, as well as convenient to throw and detach; a floating-type structure is not easy to be influenced by the change of a water surface; the adhesion area of the fish eggs is larger, and the three-dimensional space of a water body is adequately utilized; and large-scale propagation conditions can be provided for artificial breeding for fishes laying adhesive eggs living in different water layers and resource enhancement for natural populations. The three-dimensional artificial fish nest is especially suitable for artificial breeding for fishes living in the middle layer and the low layer of the water body.

Description

technical field [0001] The invention relates to a floating frame type sticky egg three-dimensional artificial fish nest. Background technique [0002] In the rivers, lakes and reservoirs of inland waters in my country, sedentary fish usually have an advantage in the community structure, and this dominance is more significant in lakes, and fishes that lay sticky eggs account for the majority of sedentary fish, among which Representative species include carp, crucian carp, and squid. This type of fish usually inhabits different water layers of the water body. During reproduction, the fertilized eggs need to adhere to the roots of aquatic plants or trees to complete the embryonic development process. With the rapid development of my country's social economy, the injection of a large number of exogenous pollutants has caused varying degrees of eutrophication in most inland lakes. The amount of aquatic plants on which humans depend has declined sharply, and the reproduction of re...
