Description
Technical field
The utility model belongs to technical field of aquaculture equipment, particularly fish-egg satellite collection device in a kind of water body.
Background technology
Fish-egg collection is the important step in artificial propagation of fish.The fish of most artificial breedings after artificial induced spawning i.e.
Generation ovulation reaction, has and voluntarily ovulates, also there is artificial collection.For example most of selachians of fish of also a small number of battalion's ovoviviparity reproductions
The fish etc. of class, four sections of Medaka shape purpose of bony fish, the Embiotocidae of Perciformes and some cotton Blenniidae, hard cheek class, its embryo hair
Educate the phase to complete in vivo, be larval stages when excreting.For this kind of voluntarily ovulation or ovoviviparity fish in production
Fish-egg（Prelarva）Collect and laid eggs more using former pond, the method for removing parent population or net cage collection, but former pond oviposition can cause
Offspring's obscures, for needing offspring individually to isolate（Such as establish family）Demand can not then meet；And net cage isolation is collected
It is cumbersome outer except taking equipment and process, the often scope of activities of the limitation parent population onset of ovulation, for it is some have particular/special requirement in
Fixed location or the fish of environment oviposition, also bring along puzzlement.Through retrieving fish-egg satellite collection device side related without discovery
The report and patent document in face.
The content of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, and to propose in a kind of water body fish-egg satellite and collect dress
Put.
The utility model solves its technical problem and takes following technical scheme to realize：
Fish-egg satellite collection device in a kind of water body, including latticed impaling portion and net bag-shaped made of nylon elastic fiber
Fish-egg collection portion, front opening of the impaling portion including left side, the afterbody opening on right side, the fin on top with fish body form fit
Opening and the ovulation mouth of lower part, the elasticity of tightening opening is sewed with the edge of front opening, afterbody opening and fin opening
Beam mouth band, has a circle forward direction thread gluing, corresponding with positive thread gluing is the reverse thread gluing of a circle, reversely viscous in the edge sewing of ovulation mouth
Button sewing is sewed with the loudspeaker for stopping fish-egg reflux below fish-egg collection portion upper shed edge, the upper shed in fish-egg collection portion
Shape shelves ring, is provided with the interior closing in for bending downward extension in the middle part of horn-like shelves ring.
Moreover, the diameter of the interior closing in is set as 1/3rd of fish-egg collection portion diameter to a quarter.
Moreover, the bottom surrounding in the fish-egg collection portion is further sewed with a circle zipper.
Moreover, the aperture of the front opening is between 2.0-1.5 times of afterbody hatch bore diameter.
Moreover, the fish-egg collection portion is the fine and close sagging type string bag, mesh specification is 80-100 mesh.
The advantages of the utility model and good effect are：
1st, for parent population, independently ovulation and the satellite farrowed and designed collect fish-egg to the utility model and prelarva device ensures
Filial generation is relatively isolated and parent population autonomic activities；
2nd, while sets of holes opening ensures that fish body is freely movable at the utility model three, the fixed effect of suspension is played；
3rd, the selection of the utility model elastic material makes device more be bonded fish body, reduces resistance movable in water, and make
Collection portion is bonded with fish body ensures collection efficiency, prevents from overflowing.It is less big to be suitable for specification gap within the specific limits at the same time
Various fish bodies.
4th, the anti-overflow valve of the utility model limits and ensures that prelarva does not escape into outside in the collection string bag.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
Present invention implementation is further described below in conjunction with attached drawing, following embodiments are descriptive, are not to limit
Property, it is impossible to protection scope of the present invention is limited with this.In following technical solutions, fish-egg collection portion not only includes fish-egg and receives
Collection, while collected including prelarva, it is intended merely to the convenience referred to as fish-egg collection portion of narration.
Fish-egg satellite collection device in a kind of water body, as shown in Figure 1, including latticed impaling made of nylon elastic fiber
Portion 2 and net bag-shaped fish-egg collection portion 9, include the front opening 1 in left side, the afterbody on right side is opened with the impaling portion of fish body form fit
Mouth 5, the fin opening 4 on top and the ovulation mouth 6 of lower part, sew at the edge of front opening, afterbody opening and fin opening
There is the elastic banding edge band 3 of tightening impaling portion opening, have a circle forward direction thread gluing 7 in the edge sewing of ovulation mouth, with positive thread gluing pair
Answer for a reverse thread gluing 8 of circle, reverse thread gluing sewing is at net bag-shaped fish-egg collection portion upper shed edge, in fish-egg collection portion
The horn-like shelves ring 10 for stopping fish-egg reflux is sewed with below upper shed, is provided with the middle part of horn-like shelves ring and bends downward extension
Interior closing in 11.
In the specific implementation of the utility model, the diameter of the interior closing in is set as net bag-shaped fish-egg collection portion diameter
1/3rd to a quarter, and for fish body when travelling, it is horn-like that the current that are formed in fish-egg collection portion drive fish-egg to pass through
The interior closing in of shelves ring slides into fish-egg collection portion bottom, and interior close up stops that fish-egg spills into cultivating pool after being back to fish body direction
In.
In the specific implementation of the utility model, further it is sewed with a circle in the bottom surrounding of the fish-egg collection portion and draws
Lock 12, pulls open the bottom that zipper opens fish-egg collection portion, the fish-egg for discharging fish-egg collection portion and being collected into being more prone to.
In the specific implementation of the utility model, the aperture of the front opening is 2.0-1.5 times of afterbody hatch bore diameter
Between, when putting on impaling portion for fish body, fish body is sent into by front opening, and fish head is maintained on the outside of front opening, and this structure is set
Count and install mode and easily facilitate operation, reduce damage of the operating process to fish body.
In the specific implementation of the utility model, the grid in the impaling portion is uniform but not fine and close, and elastic network(s) ruling is close to
Fish body, reduces fish body swimming resistance, the fish-egg collection portion is the fine and close sagging type string bag, and mesh specification is 80-100 mesh.
In the specific implementation of the utility model, it is poor that elastic material can make the device be suitable for specification within the specific limits
Away from less big various fish bodies, and front opening, the afterbody opening on right side, the fin opening on top and the ovulation of lower part mouth it is big
Small and position is adjusted all in accordance with the needs of actual fish body species.
