Problems solved by technology

In the past, carp nests made of brown chips, tree roots, aquatic plants, etc., often scattered on the bottom of the pond, which was troublesome and time-consuming to remove, and easily damaged the fry
In addition, the material of these fish nests affects the attachment rate of fertilized eggs. The hatching rate of fertilized eggs that sink to the bottom of the pond is very low, which reduces the overall hatching rate. Dead eggs are prone to mold and corruption, and are not easy to remove. Survival rate and growth of fry

Embodiment Construction

[0011] Such as figure 1 The embodiment of a kind of carp nest shown:

[0012] 1. Fish nest frame. Fish nest frame is rectangular parallelepiped, is spliced ​​by PVC pipe 1, and PVC pipe is filled with sand, and frame length, width, height are respectively 50cm, 40cm, 40cm.

[0013] Two, the double-layer mesh sheet 2 is installed on the surface of 0.5m * 0.4m in fish nest frame specification.

[0014] 3. On the three surfaces of the double-layer mesh sheet 2 of the device, use nylon ropes to bind the mesh cloth 1 with a specification of 25 meshes at a distance of 5 cm. The size of the mesh cloth is 20 cm × 10 cm.

[0015] 4. Before breeding, the fish nest is disinfected; when breeding, place the side that is not equipped with mesh facing up, and a pair of broodstock is placed in a fish nest; after breeding, the fish nest is cleaned and stored.

Abstract

The invention discloses a carp nest, which is characterized by comprising a peripheral frame and a net arranged on the frame surface, wherein the frame is a cuboid, and is formed by splicing hollow tubes; a cavity of the frame is filled with sand soil; two opposite surfaces of the frame in the height direction are hollow, the other surfaces of the frame are provided with two-layer nets; except the top two-layer net, other two-layer nets are externally bound with net cloth; and when the net cloth is bound, the net cloth is folded in half, and is bound onto the net along the folding line. The carp nest is firm in structure, can keep water in a hatching pond clean, is high in production inducing capacity, adhesion, air permeability and light transmission, can improve fertilization and hatching rates, is time-saving and labor-saving in recovery, can reduce the loss of fries, is durable, and convenient to clean, disinfect and store, can be repeatedly used, saves financial resources and human resources, can eliminate adverse effects of a material of the traditional carp nest on germ cell hatching and fry survival and growth of carp, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of fish breeding, in particular to a novel carp nest for carp breeding. Background technique [0002] Carp is a traditional cultured fish in my country, and it is also one of the most important freshwater cultured species in China. It is distributed all over the country. When carp breeds, it is necessary to place fish nests and collect fertilized eggs to increase the hatching rate. In the past, carp nests made of brown chips, tree roots, aquatic plants, etc. often left residues scattered on the bottom of the pond, which was troublesome and time-consuming to remove, and easily damaged the fry. In addition, the material of these fish nests affects the attachment rate of fertilized eggs. The hatching rate of fertilized eggs that sink to the bottom of the pond is very low, which reduces the overall hatching rate. Dead eggs are prone to mold and corruption, and are not easy to remove. Survival rate and growth of fry. C...
