Abstract
The utility model relates to an odontobutis-obscura wooden ovipositor, which is characterized by mainly comprising a barrel body (1) and net cloth (2), wherein the barrel body (1) comprises an upper edge plate (3) and a lower edge plate (4) which are mutually parallel as well as two inclined edge plates (5) which are used for connecting the upper edge plate (3) and the lower edge plate (4), the cross section of the barrel body (1) is in a trapezoidal structure, both ends of the barrel body (1) are communicated, and the net cloth (2) is positioned on the inner lateral surface of each inclined edge plate (5). The odontobutis-obscura wooden ovipositor has a simple structure, and the designed ovipositor has a proper size and a reasonable shape, is quite suitable for the ovipositing habit of an odontobutis obscura, has a high ovipositing rate, is convenient to collect and transfer and convenient to clean and is suitable for being repeatedly used.
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 wooden Odontobutis obscura 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 decline of China's water body quality in recent years, 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 breed and have crucial economic worth, and carry out the hatching that the key of propagating artificially is a fry, the key of fry hatching is the collection of fish-egg.Because the Odontobutis obscura under wild state hobby is mostly 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, treat that again tile being put into the hatchery after fish lays eggs hatches, though this tile type oopod can be realized the collection of fish-egg, because its structure is comparatively simple, otherness is bigger, has had a strong impact on the raising of Odontobutis obscura spawning rate, simultaneously to follow-up hatching also quite inconvenience.
Summary of the invention
The purpose of this utility model is the problem that is unfavorable for improving spawning rate at the oopod that uses in the existing Odontobutis obscura artificial propagation, designs a kind of simple in structurely, meets the lay eggs wooden oopod of Odontobutis obscura of characteristic of Odontobutis obscura.
The technical solution of the utility model is:
The wooden oopod of a kind of Odontobutis obscura, it is characterized in that it mainly is made up of cylindrical shell 1 and screen cloth 2, two hypotenuse plates 5 by the last side plate 3 that is parallel to each other, time side plate 4 and last side plate 3 of connection and following side plate 4 of described cylindrical shell 1 are formed, its cross section is trapezium structure and two ends connect, and described screen cloth 2 is positioned on the medial surface of described hypotenuse plate 5.
All be positioned with screen cloth 2. on described two hypotenuse plates 5
The inboard, two ends of described hypotenuse plate 5 or the outside respectively are fixed with a nylon pin thread or box 6, and the two ends of described screen cloth 2 respectively are provided with the nylon box or the pin thread 7 that match with described nylon pin thread or box 6.
The beneficial effects of the utility model:
The utility model is simple in structure, and designed oopod size is suitable, and shape is reasonable, is suitable for very much the spawning habit of Odontobutis obscura, has the spawning rate height, collects convenient transfer, and cleans conveniently, is suitable for using repeatedly.
The utility model both can rely on the characteristic of drowning oneself after the timber suction to make it the heavy bottom that places, also can make it to fall to reliably the bottom at the upper bottom surface pressurization stone or the iron block of trapezoidal cylindrical shell, the structure that two ends connect helps flowing of current, increases the water body oxygen content in the ovum device.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of cylindrical shell of the present utility model.
Fig. 3 is the structural representation of screen cloth of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Figure 1-3.
The wooden oopod of a kind of Odontobutis obscura, it mainly is made up of cylindrical shell 1 and screen cloth 2, as shown in Figure 1, the two ends of described cylindrical shell 1 connect, its cross section is trapezium structure, trapezoidal upper bottom surface can be used for placing stone or iron block so that it can fall to the bottom reliably, as shown in Figure 2, cylindrical shell 1 of the present utility model is by the last side plate 3 that is parallel to each other, following side plate 4 and connection are gone up two hypotenuse plates 5 of side plate 3 and following side plate 4 and are formed, its cross section is trapezium structure and two ends connect, all can be positioned with screen cloth 2 on the medial surface of one or two hypotenuse plate 5, screen cloth 2 can be by the flexible connection of velcro realization with hypotenuse plate 5, can respectively be fixed with a nylon pin thread or box 6 in the inboard, two ends or the outside of hypotenuse plate 5, respectively be provided with a nylon box or a pin thread 7 that matches with described nylon pin thread or box 6 simultaneously at the two ends of screen cloth 2.
Can be in the time of need laying eggs with on the velcro that earlier velcro at net sheet 2 two ends is overlapped on the hypotenuse plate of 1 of cylindrical shell, be placed in the water body then, light and noise control environment, keep water body to flow, wait to lay eggs and finish and oopod can be taken out the water surface, the net sheet is taken off placing the hatchery to hatch from oopod.The utility model not only can improve spawning rate, and helps improving incubation rate.Cylindrical shell and net sheet can be cleaned up after hatching finishes and use again the coming year.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (3)
