Description

Fry catching device

Technical Field

The utility model relates to a catch device, concretely relates to in-process that effectively filters, reduces tradition to fry is caught injury, improvement fry survival rate's fry catch device to fry.

Background

The fry is also called 'fish blossom', young fish which is hatched shortly are generally 6-9 mm in length, the fry is weak in fingerling, and the individual size of the fry is small, so that the fry is poor in swimming activity, and the fry is mainly eaten by eating rotifers, nauplii and small cladocera; the fry generally swim dispersedly at the sides and on the surface of the pond, a few of clusters swim gradually, and after the fry are cultured for a period of time, the larger fry need to be caught for stocking, so that a catching device is needed.

Traditional fry fishing device, complex operation, also catch unqualified less fry together easily, can not effectively filter the fry, not only cause mechanical injury to the fry in the operation process easily, moreover fish fry is fished out and can make the fry appear short-lived lack of water after breeding the fish pond, the fry can be ceaselessly struggled this moment, a small amount of fry is pressed dead phenomenon can appear, the fry can damage the fish scale when struggling simultaneously, the survival rate after stocking is lower, therefore, we propose a fry fishing device to solving above-mentioned problem.

Disclosure of Invention

The utility model aims at providing a fry fishing device which effectively screens the fry, reduces the injury to the fry and improves the survival rate of the fry in the traditional fishing process.

In order to solve the above problem, the utility model provides a following technical scheme: the utility model provides a fry fishing device, includes first box with a net, second box with a net and the intercommunication net of first box with a net of intercommunication and second box with a net, first box with a net and second box with a net include netting and frame, the top of first box with a net is provided with first bait entry, and the top of second box with a net is equipped with second bait entry, the bottom opening and the fixedly connected with stainless steel bucket of first box with a net, first box with a net and stainless steel bucket are linked together, are provided with into fish mouth on the side of one side of first box with a net, be equipped with out the fish mouth on the lateral wall of stainless steel bucket, it is provided with outer spiral line to go out the outside protrusion of fish mouth and bulge, go out the threaded connection on the fish mouth and have supporting spiral cover, the lateral wall of first box with a net and the lateral wall of second box with a net are equipped with the connector respectively, and first box with a net is connected with the intercommunication net through the connector.

Furthermore, the mesh density of the communicating net is the same as that of the first net box and the second net box, and the netting of the first net box and the second net box can be detached from the frame.

Furthermore, four pull rods are arranged above the first net cage and the second net cage respectively, and the pull rods of the first net cage are connected with plastic floating balls through net wires.

Compared with the prior art, the beneficial effects of the utility model are as follows: this fry fishing device simple structure, convenient operation can not only reduce the mechanical injury that causes the fry in the operation process, can carry out effectual screening to the fry moreover, improves the survival rate of fry.

The notation in fig. 1 illustrates: 1. a first net cage; 2. a second net cage; 3. a communicating net; 4. a first bait inlet; 5. a second bait inlet; 6. a frame; 7. a fish inlet; 8. a stainless steel barrel; 9. a connecting port; 10. a fish outlet; 11. a pull rod; 12. a network cable; 13. plastic floating ball.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to fig. 1, a fry catching device comprises a first net cage 1, a second net cage 2 and a communicating net 3, wherein the first net cage 1 and the second net cage 2 are of a cuboid structure and comprise a netting and a frame 6, a first bait inlet 4 and a second bait inlet 5 are respectively arranged above the first net cage 1 and the second net cage 2 and used for placing bait, a stainless steel barrel 8 is fixedly connected to the bottom opening of the first net cage 1, the first net cage 1 is communicated with the stainless steel barrel 8 to prevent a fry from short-term water shortage after the fry is fished out from a fishpond and a small amount of the fry is crushed, a fish outlet 10 is arranged on the side wall of the stainless steel barrel 8, the fish outlet 10 protrudes outwards, a protruding part of the fish outlet 10 is provided with a spiral line, a spiral cover matched with the protruding spiral line of the fish outlet 10 is further arranged on the left side wall of the right side wall of the first net cage 1 and the left side wall of the second net cage 2 are respectively provided with a connecting port 9, first box with a net 1 and second box with a net 2 pass through connector 9 and connect with intercommunication net 3, the mesh density of intercommunication net 3 is the same with the mesh density of first box with a net 1, second box with a net 2 and the etting of first box with a net 1 and second box with a net 2 can be dismantled with frame 6, and the etting of the different meshes of size installation that the fry was caught as required to the convenience, respectively there are four pull rods 11 above first box with a net 1 and second box with a net 2, is convenient for mention the box with a net after catching, be connected with plastics floater 13 through net twine 12 on the pull rod of first box with a net 1, the concrete position of device in the pond is caught in the monitoring.

The utility model discloses a theory of operation: during the specific use, place the suitable position in the pond with first box with a net 1 and second box with a net 2 that the spiral cover was screwed up earlier, first bait entry through first box with a net 1 drops into the bait package, attract the fry to get into in first box with a net 1, a period of time later, take out the bait package of first box with a net 1, and drop into a small amount of bait package at second bait entry, attract unqualified little fry to enter into second box with a net 2 along intercommunication net 3, big fry then because mesh internal diameter undersize and stay in first box with a net 1, after a period, salvage the box with a net, because first box with a net 1 part is stainless steel bucket 8 down, make qualified fry salvaged can not lead to the survival rate reduction of fry because of the lack of water, unscrew the spiral cover, pour out the fry.

The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto, and any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
