Abstract
The utility model discloses double-layer artificial fish nest, it includes left frame and correct frame, it is connected with each other by the more bottom being equidistantly arranged in parallel connecting ropes and careless bar between the left frame and the bottom side of correct frame, is connected with each other between the left frame and the top side of correct frame by the more top being equidistantly arranged in parallel connecting ropes and careless bar.The fish nest can not only improve the affinity to fish, expand spawning space and area, can also prevent most of ovum from falling into the water, improve the survival rate and incubation rate of ovum.
Description
Technical field
A kind of artificial fish nest for being used to produce viscid egg fish natural propagation is the utility model is related to, suitable for various slow stationary streams
The natural propagation of viscid egg fish is produced in water body.
Background technology
Expanding economy exerts a certain influence to the living environment and stock number of fish, therefore, to take some
Such as artificial fish nest help of work technological means produces viscid egg fish natural propagation and recovers its resource.In practice, existing Artificial Fish
Nest is inadequate to the affinity of fish, and the ovum that fish lays eggs or produced not above only has small part ovum to be adhered on fish nest, largely falls into
It is unfavorable for the survival and hatching of ovum in water, the utilization rate of artificial fish nest is not high.
Utility model content
In view of the above-mentioned problems, technical problem to be solved in the utility model is exactly to provide one kind for production viscid egg fish
The double-deck obstetric table artificial fish nest of natural material, the fish nest can not only improve the affinity to fish, expand spawning space and face
Product, can also prevent most of ovum from falling into the water, improve the survival rate and incubation rate of ovum.
In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：Double-layer artificial fish nest, it is wrapped
Left frame 1 and correct frame 4 are included, is equidistantly arranged in parallel by more between the left frame 1 and the bottom side of correct frame 4
Bottom connecting rope 8 and careless bar 2 are connected with each other, equidistantly flat by more between the left frame 1 and the top side of correct frame 4
The top connecting rope 3 and careless bar 2 of row arrangement are connected with each other.
Careless bar 2 is all in series with equal intervals in every the top connecting rope 3 and bottom connecting rope 8.
The base two corners of the correct frame 4 are all connected with sinker 7 and anchor 5 by anchoring rope 6.
The left frame 1 and correct frame 4 are all assembled using natural bamboo material.
The every careless bar 2 all by a section bamboo bar it is vertical be cut into two middles and reclamp to close up after natural waterweeds form.
The utility model has the advantages that：
1st, fish nest is fixed in water by sinker and anchor, anchoring rope lengthening can make artificial fish nest with fluctuation in stage and upper and lower
Float.
2nd, this fish nest main material uses natural bamboo bar and has the pasture and water of affinity to fish, and the attraction of fish is added
By force.
3rd, on the one hand the double-deck obstetric table structure that this fish nest uses can expand fish spawning space and area, on the other hand may be used
The most of ovum for making fish be fallen when upper strata obstetric table is laid eggs falls into lower floor's obstetric table, improves the survival rate and incubation rate and fish nest of ovum
Utilization rate.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model overall structure diagram.
In figure：Left frame 1, careless bar 2, top connecting rope 3, correct frame 4, anchor 5, anchoring rope 6, sinker 7, bottom connecting rope 8.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
In Fig. 1, double-layer artificial fish nest, it includes the bottom of left frame 1 and correct frame 4, the left frame 1 and correct frame 4
It is connected with each other between portion side by the more bottom being equidistantly arranged in parallel connecting ropes 8 and careless bar 2, the left frame 1 and the right side
It is connected with each other between the top side of framework 4 by the more top being equidistantly arranged in parallel connecting ropes 3 and careless bar 2.
Further, careless bar 2 is all in series with equal intervals in every the top connecting rope 3 and bottom connecting rope 8.Pass through
Being in series with careless bar 2 attracts fish to be laid eggs above, ensure that fish-egg can smoothly fall on careless bar 2, and then facilitate fish-egg
Hatching.
Further, the base two corners of the correct frame 4 are all connected with sinker 7 and anchor 5 by anchoring rope 6.Pass through sinker 7
The fixation of whole fish nest is facilitated, the fixation of whole fish nest is also ensure that by anchor 5, prevents it from occurring excessive under water slug
Scope moves.
Further, the left frame 1 and correct frame 4 are all assembled using natural bamboo material.Using natural bamboo material
Material ensure that the affinity to fish, and material is easier to obtain, and reduces cost.
Further, the every careless bar 2 is all closed up by vertical be cut into after natural waterweeds are reclamped in two middles of section bamboo bar
Form.Affinity to fish can be improved using natural bamboo and pasture and water material, attract fish to be laid eggs on fish nest, and then ensured
Fish-egg can smoothly be hatched on its surface, improve the incubation rate of fish-egg.
The course of work and operation principle of the present utility model are：
In the bottom of correct frame 4 the connection sinker 7 of anchoring rope 6 and anchor 5, fish nest is fixed in water by sinker 7 and anchor 5,
Anchoring rope 6 lengthens and artificial fish nest can be made to be fluctuated with fluctuation in stage.This fish nest main material is using natural bamboo bar and to fish
Class has the pasture and water of affinity, and the attraction of fish is strengthened；On the one hand the double-deck obstetric table structure that this fish nest uses can expand fish
Class spawning space and area, on the other hand can make most of ovum that fish fall when upper strata obstetric table is laid eggs fall into lower floor's obstetric table,
Improve the survival rate and the utilization rate of incubation rate and fish nest of ovum.
Above-described embodiment is used for illustrating the utility model, rather than the utility model is limited, in this practicality
New spirit and any modifications and changes in scope of the claims, made to the utility model, both fall within this reality
With new protection domain.
