Abstract

The utility model relates to a special fish net for viscous fish eggs, which comprises a bamboo pole (1) and connecting ropes (2), and is characterized in that the bamboo pole is provided with a group of connecting ropes, and the lower end of each connecting rope is respectively and fixedly connected with willow root (3). The utility model has the beneficial effects that the special fish net for viscous fish eggs is applicable to mass large-scale centralized production, has simple structure, convenient use, low manufacturing cost and high incubation survival rate.

Description

The special-purpose fish nest of viscosity fish-egg

Technical field

The utility model relates to the fish culture apparatus, especially a kind of special-purpose fish nest of fish production hatching viscosity fish-egg that is used for.

Background technology

At present, traditional hatching pattern, the general employing is that parent population is carried out induced spawning, natural spawning is on pasture and water, these pasture and water are as the hatching nest of fish-egg, this fish nest is the part of natural plants, the one, be not easy to the large-scale industrialization pooled applications, and bigger shortcoming is that these pasture and water only are suitable for the fish natural spawning, natural spawning is low in the fish-egg density of pasture and water, fry output is little, directly influences the planned commercialization operation of growing seedlings of carrying out, and has become the key technology that the restriction fry produces.

The utility model content

The purpose of this utility model is exactly to have the defective that the inapplicable extensive fry of nature fish nest produces now in order to overcome, and provides a kind of viscosity fish-egg special-purpose fish nest.

The technical scheme that its technical problem that solves the utility model adopts is:

The special-purpose fish nest of viscosity fish-egg comprises bamboo pole and connection cord, and it is characterized in that: bamboo pole is provided with one group of connection cord, and each connection cord lower end difference fixedly connected is the willow fibrous root.

The bamboo pole diameter is generally 1～2cm, length is 3～6m, and the willow fibrous root that will be bundled into wisp with connection cord fixedly is suspended on the bamboo pole then.

On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme: the spacing of adjacent two willow fibrous roots is 5～7cm.

A willow fibrous root is twined mutually by two above willow fibrous roots and constitutes, and two above willow fibrous roots twine and constitute ellipticity fish nest.

The beneficial effects of the utility model are to be fit to extensive centralized production in enormous quantities; Simple in structure, easy to use; Low cost of manufacture, hatching survival rate height.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is an A-A cutaway view of the present utility model.

1. bamboo poles among the figure, 2. connection cord, 3. willow fibrous root.

Embodiment

As shown in Figure 1, the special-purpose fish nest of the utility model viscosity fish-egg, comprise bamboo pole, the bamboo pole diameter is generally 1～2cm, length is 3～6m, and bamboo pole is provided with one group of connection cord, and each connection cord lower end difference fixedly connected is the willow fibrous root, the spacing of adjacent two willow fibrous roots is 5cm, as shown in Figure 2, one twines the willow fibrous root mutually by 15 willow fibrous roots and to constitute, and 15 willow fibrous roots twine and constitute ellipticity fish nests.

Same as above, one twines the willow fibrous root mutually by 20 willow fibrous roots and to constitute, and the spacing of adjacent two willow fibrous roots is 7cm.

In the morning of putting into the previous day in the pond of carp, water in the pond is discharged 80%, allow the carp back accept sunlight and be exposed to the sun 3-4 hour, the new water of annotating at dusk is consistent with the former water level in pond, put into the special-purpose fish nest of viscosity fish-egg at about 9 at night, then the bamboo bar is put in the water in pond, 5cm gets final product apart from the water surface, and at this moment carp obtains beginning to lay eggs on a large scale behind the special-purpose fish nest of viscosity fish-egg, can take out the special-purpose fish nest of viscosity fish-egg early morning, put into special-purpose hatching pond and hatch.

Claims

1. the special-purpose fish nest of viscosity fish-egg comprises bamboo pole (1) and connection cord (2), and it is characterized in that: bamboo pole is provided with one group of connection cord, and each connection cord lower end difference fixedly connected is willow fibrous root (3).

2. the special-purpose fish nest of viscosity fish-egg according to claim 1, it is characterized in that: the spacing of adjacent two willow fibrous roots (3) is 5～7cm.

3. the special-purpose fish nest of viscosity fish-egg according to claim 1 and 2 is characterized in that: one twines willow fibrous root (3) mutually by two above willow fibrous roots and to constitute.
