Abstract
A PVC (polyvinyl chloride) tube hatchery for odontobutis obscurus is characterized by comprising a PVC tube (1) and an elastic hook (2), two ends of the PVC tube are through, two inserting holes (4) for hanging the elastic hooks (2) are symmetrically arranged at one end of the PVC tube, and at least two groups of 'splayed' supporting legs (3) are mounted on the tube wall. The PVC tube hatchery for odontobutis obscurus has the advantages of simple structure, low cost, good settleability and convenience in cleaning, and is higher in spawning rate than an existing tile hatchery.
Description
Technical field
The utility model relates to a kind of fishery cultural technique, especially a kind of fish breeding incubation equipment, specifically a kind of Odontobutis obscura pvc pipe oopod.
Background technology
Odontobutis obscura is a kind of delicious meat, nutritious aquatic products, and extensive growth is the higher aquatic products of a kind of economic worth in the basin, rivers and lakes of China.
Because the breeding of Odontobutis obscura is had relatively high expectations to water body, reproduction rate under its wild state is not high, add the in recent years decline of China's Water quality, cause the Odontobutis obscura quantity of producing under the wild condition sharply to descend, cause its market price high, institute's quantity of selling is very limited on the market at present, therefore, carry out artificial propagation and have very important economic worth with cultivation, and carry out the hatching that the key of propagating artificially is fry, the key of fry hatching is the collection of fish-egg.Because the Odontobutis obscura under the wild state mostly hobby is laid eggs under stone or tile, therefore the domestic and international artificial spawning that carries out is the tile of placing some in water body mostly, again tile being put into the hatchery after fish lays eggs hatches, although this tile type oopod can be realized the collection of fish-egg, because its structure is comparatively simple, otherness is larger, had a strong impact on the raising of Odontobutis obscura spawning rate, to follow-up hatching also quite inconvenience, for this reason, the applicant designs a kind of simple in structure simultaneously, make, easy to clean, the pvc pipe oopod of high conformity is to adopt the mode of rope hanging to be positioned over the bottom but the applicant finds this oopod, and the workload of aspect suspention is very not large, on the other hand, during suspention, the distance at the horizontally-arranged dried up end of pvc pipe is difficult to grasp, if the dried up end is too near, be unfavorable for the words that Odontobutis obscura is swum across, then Odontobutis obscura probably produces ovum outside the pvc pipe wall, and therefore, this pvc pipe oopod must be improved.
Summary of the invention
The purpose of this utility model is the problem that is unfavorable for improving spawning rate for the oopod that uses in the existing Odontobutis obscura artificial propagation, designs a kind of simple in structurely, meets the lay eggs Odontobutis obscura pvc pipe oopod of characteristic of Odontobutis obscura.
The technical solution of the utility model is:
A kind of Odontobutis obscura pvc pipe oopod, it is characterized in that it is comprised of pvc pipe 1 and elastic hook 2, the two ends of this pvc pipe connect, and are arranged with for two jacks 4 that hang elastic hook 2 at an end of described pvc pipe, at tube wall the feet 3 that at least two groups are " eight " shape structure are installed.
The diameter of described pvc pipe 1 is 15-25 centimetre, and optimum diameter is 16 centimetres, and it highly is 30-50 centimetre.
Described feet 3 is comprised of stay bolt 5 and nut 6, and an end of stay bolt passes and is fixed on the pvc pipe wall with nut from the inwall of pvc pipe 1.
The lower end of described feet 3 is the 30-50 millimeter from the height of the minimum point of pvc pipe 1, optimum height be 40 millimeters so that Odontobutis obscura swim across from the bottom of pvc pipe.
The beneficial effects of the utility model:
The utility model is simple in structure, advantage with low cost.Can directly the PVC downpipe of extensively selling on the market be blocked and be processed into required length, it is good that it has settleability, and the advantage of easy to clean, spawning rate are better than existing tile oopod.
The utility model adopts the height at the dried up end of feet positioning control oopod, and it is convenient to place, and can directly sink under water, and automatically controls the height at the dried up end of tube wall, lays eggs to hang up elastic hook after finishing and can be suspended in the hatchery and hatch.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model hatching view.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of Odontobutis obscura pvc pipe oopod, it is comprised of pvc pipe 1 and elastic hook 2, elastic hook 2 preferably adopts corrosion resistant stainless steel material to bend, and the two ends of this pvc pipe connect, the symmetrical jack 4 that is used for plug-in mounting elastic hook 2 two ends on an end of described pvc pipe.The diameter of described pvc pipe 1 can be 15-25 centimetre, optimum diameter is 16 centimetres, it highly is to select between 30-50 centimetre, for the ease of oopod of the present utility model is positioned in the water body of laying eggs fast, the utility model has been installed two groups of splayed feets 3 at the pipe outer wall, as shown in Figure 1, splayed feet 3 can adopt stainless steel bolt 5 and stainless steel nut 5 to make, one end of stainless steel bolt 5 passes outside the pipe in managing, rely on the bolt head location in the pipe, prevent that it from skidding off outside the pipe, outside the pipe, screw by nut 5, thereby make Bolt to position form feet at tube wall, the height of feet 3 (minimum point is from the distance between the minimum point of pvc pipe) is generally 30-50 millimeter, preferably 40 millimeter.Can directly purchase from the market the PVC water pipe that meets the diameter requirement during concrete the manufacturing and cut off and process bolt hole, elastic hook jack 4 with electric drill, the stainless steel bolt nut is fixed in the bolt hole gets final product.
Can directly pvc pipe of the present utility model be horizontally-arranged in the water body of laying eggs in the time of need to laying eggs, after Odontobutis obscura is laid eggs end, again the two ends of elastic hook 2 are inserted in the corresponding jack, again product there is the pvc pipe of ovum to be suspended in the hatchery, make the upper end of pvc pipe place 10 centimetres of underwaters, in water body, lead to oxygen, control corresponding water temperature and illuminance and noise and can finish hatching.Oopod of the present utility model can improve spawning rate more than 30%, and spawning rate is stabilized in more than 95%.After hatching finishes pvc pipe being lifted from the water surface carries out can supplying reuse the coming year behind the cleaning and sterilizing.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
