Abstract
The invention relates to a special fish nest for viscous roes, which comprises a bamboo pole (1) and connecting ropes (2). The fish nest is characterized in that: a group of connecting ropes are arranged on the bamboo pole; and a bundle of willow tassels (3) is fixedly connected to the lower end of each connecting rope. The special fish nest has the advantages of suitability for large-batch and large-scale centralized production, simple structure, convenience for use, low manufacturing cost and high hatching survival rate.
Description
Technical field
The present invention 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.
Summary of the invention
Purpose of the present invention 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 solution adopted for the present invention to solve the technical problems 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 palpus.
The bamboo pole diameter is generally 1～2cm, length is 3～6m, and will be bundled into the willow of wisp with connection cord then must fixedly be suspended on the bamboo pole.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
The spacing of adjacent two willows palpus is 5～7cm.
A willow must must be twined mutually by two above willows and be constituted, and two above willows must be twined and be constituted ellipticity fish nest.
The invention has the beneficial effects as follows and be fit to extensive centralized production in enormous quantities; Simple in structure, easy to use; Low cost of manufacture, hatching survival rate height.
The present invention is further described below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is a front view of the present invention;
Fig. 2 is an A-A cutaway view of the present invention.
1. bamboo poles among the figure, 2. connection cord, 3. willow palpus.
Embodiment
As shown in Figure 1, the special-purpose fish nest of viscosity fish-egg of the present invention, 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 must willow, the spacing of adjacent two willows palpus is 5cm, as shown in Figure 2, one must must be twined willow mutually by 15 willows and to constitute, and 15 willows must be twined and be constituted ellipticity fish nests.
Same as above, one must must be twined willow mutually by 20 willows and to constitute, adjacent two willows must spacing be 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 (3)
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 palpus (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 willows palpuses (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 willow must (3) by two above willows mutually winding constitute.
