Description
Technical Field
The invention belongs to the technical field of aquaculture equipment, and particularly relates to a device for collecting fish eggs in a water body along with the water body.
Background
Roe collection is an important link in fish artificial propagation. Most of the artificially bred fishes undergo ovulation reaction after artificial spawning, and are automatically ovulated and also manually collected. There are also a small number of oogonial reproduction fishes such as most cartilaginous fishes, four families of medaka class of teleostomid class, a crucian family of perciformed class, and several eel, hard cheek class fishes, etc., whose embryonic development stage is completed in vivo and is already at the fry stage when discharged outside the body. In production, the method of spawning in an original pond, moving out parent fishes or collecting fish fries in a net cage is mostly adopted for collecting the fish spawns (fish fries) of the self-ovulating or oviparous fishes, but the spawning in the original pond can cause the confusion of offspring, and the requirement for independent isolation of the offspring (such as establishment of families and the like) can not be met; besides occupying complicated equipment and process, the isolated collection of the net cages often limits the range of motion of the ovulation period of parent fishes, and brings troubles to certain fishes which have special requirements for spawning in fixed places or environments. The search shows no report and patent literature about the fish egg satellite collecting device.
Disclosure of Invention
The invention aims to provide a device for collecting roes in a water body along with the body, aiming at the defects of the prior art.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
roe satellite collecting device in water, including the latticed portion of wearing to hang and pocket form roe collection portion that nylon elastic fiber made, wear the portion of hanging including left front opening with fish body shape fit, the afterbody opening on right side, fin opening and the ovulation mouth of lower part on upper portion, front opening, the elastic tying of tightening up the open-ended area is all made up at the edge of afterbody opening and fin opening, make up a round forward thread gluing at the edge of ovulation mouth, it is the reverse thread gluing of round that corresponds with forward thread gluing, reverse thread gluing is made up at roe collection portion upper shed edge, make up the loudspeaker form shelves ring that blocks the roe backward flow below the upper shed in roe collection portion, open at the middle part of loudspeaker form shelves ring and have the interior binding off of buckling extension downwards.
Further, the diameter of the inner shell is set to be one third to one fourth of the diameter of the roe collecting portion.
And a circle of zipper is further sewn around the bottom end of the fish egg collecting part.
Moreover, the aperture of the front opening is between 2.0 and 1.5 times the aperture of the rear opening.
And the roe collecting part is a compact drooping type net bag with the mesh specification of 80-100 meshes.
The invention has the advantages and positive effects that:
1. the on-body fish egg collecting and fish fry device designed aiming at the autonomous ovulation and the fish spawning of the parent fish ensures the relative isolation of offspring and the autonomous activity of the parent fish;
2. the three trepanning openings of the invention ensure that the fish body can freely move and play a role in hanging and fixing;
3. the device is more attached to the fish body due to the selection of the elastic material, so that the resistance to movement in water is reduced, the collection efficiency is ensured by attaching the collection part to the fish body, and the overflow is prevented. Meanwhile, the method is suitable for various fish bodies with small specification difference in a certain range.
4. The anti-overflow valve limits and ensures that the larval fish does not escape to the outside in the collecting net bag.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The present invention will be further described with reference to the following drawings, which are illustrative, not restrictive, and the scope of the invention is not limited thereto. In the following technical solutions, the roe collecting unit includes not only roe collection but also fry collection, but also roe collection for convenience of description.
A fish egg satellite collecting device in a water body comprises a grid-shaped hanging part 2 and a net-bag-shaped fish egg collecting part 9 which are made of nylon elastic fibers, wherein the hanging part matched with the shape of a fish body comprises a front opening 1 on the left side, a tail opening 5 on the right side, a fin opening 4 on the upper part and an ovulation opening 6 on the lower part, elastic tying belts 3 for tightening the opening of the hanging part are sewn at the edges of the front opening, the tail opening and the fin opening, a circle of forward sticky buckles 7 are sewn at the edge of the ovulation opening, a circle of reverse sticky buckles 8 correspond to the forward sticky buckles, the reverse sticky buckles are sewn at the edge of the upper opening of the net-bag-shaped fish egg collecting part, a horn-shaped blocking ring 10 for blocking backflow of fish eggs is sewn below the upper opening in the fish egg collecting part, and an inward closing opening 11 which is bent and extended downwards is formed in the middle of the horn-shaped blocking ring.
In the specific implementation of the invention, the diameter of the inner closing-in is set to be one third to one fourth of the diameter of the net-bag-shaped roe collecting part, when a fish body moves, water flow formed in the roe collecting part drives the roes to smoothly slide to the bottom of the roe collecting part through the inner closing-in opening of the horn-shaped retaining ring, and the inner closing-in opening prevents the roes from flowing back to the direction of the fish body and then being scattered into the culture pond.
In the specific implementation of the invention, a circle of zipper 12 is further sewn around the bottom end of the roe collecting part, and the bottom end of the roe collecting part is opened by pulling the zipper, so that the roe collected by the roe collecting part is released more easily.
In the specific implementation of the invention, the aperture of the front opening is 2.0-1.5 times of the aperture of the tail opening, when the fish body is put on the hanging part, the fish body is fed from the front opening, and the fish head is kept outside the front opening.
In the specific implementation of the invention, the grids of the wearing part are uniform but not compact, the elastic grid lines are tightly attached to the fish body, the swimming resistance of the fish body is reduced, the fish egg collecting part is a compact drooping type net bag, and the specification of the mesh is 80-100 meshes.
In the specific implementation of the invention, the elastic material can ensure that the device is suitable for various fish bodies with small specification difference in a certain range, and the sizes and the positions of the front opening, the right tail opening, the upper fin opening and the lower ovulation opening are adjusted according to the requirements of actual fish body types.
