The utility model discloses a set up the drainage board in the cell body, two -layer about dividing into aquaculture water body, female chinese king crab is stayed in in upper water, lay eggs in the sand bed, and the air supply pipe has both increased the dissolved oxygen through the continuous air feed of the sleeve pipe that runs through the drainage board, makes the grains of sand of sand bed obtain rinsing in the circulation flow of upper and lower two -layer water again, reaches the sand bed and from uncontaminated effect, has improved the embryonated egg survival rate of chinese king crab.
Description
Technical field
The utility model relates to a kind of spawning pond, is specifically related to a kind of spawning pond improving Tachypleus tridentatus fertilized egg survival rate.
Background technology
Tachypleus tridentatus is a kind of living fossil animal, within 2004, is just defined as animals on the brink of extinction by China.Carrying out artificial breeding, by enhancement releasing, supplement wild resource, is the important measures recovering Tachypleus tridentatus resource.In conventional art, by gaza in large water body pond, promoting that Tachypleus tridentatus is laid eggs, is that the most frequently used Tachypleus tridentatus is laid eggs method.
But this method Problems existing of laying eggs is that sand bed is too thin, Tachypleus tridentatus is laid eggs few, and sand bed is too thick, easily pollutes again at the bottom of pond, causes Tachypleus tridentatus fertilized egg survival rate low.
Therefore, need to design a kind of novel spawning pond, the adverse effect of prior art to Tachypleus tridentatus fertilized egg can be overcome, improve the fertilized egg survival rate of Tachypleus tridentatus.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of spawning pond improving Tachypleus tridentatus fertilized egg survival rate, can improve husky environment, increase dissolved oxygen simultaneously, improves the fertilized egg survival rate of Tachypleus tridentatus.
For achieving the above object, the utility model provides following technical scheme:
A kind of spawning pond improving Tachypleus tridentatus fertilized egg survival rate, comprise pond body, water filter plate, for supporting the supporting brick of water filter plate, feed pipe, drainpipe and air supply pipe, described supporting brick is spaced on body bottom surface, pond, described water filter plate level is laid on supporting brick, described water filter plate is equipped with bolting silk cloth, sand bed laid by described bolting silk cloth, described water filter plate is provided with leaking hole and the sleeve pipe passing vertically through water filter plate, insert in sleeve pipe after the gas outlet socket gas stone of described air supply pipe, described feed pipe to be laid on bottom the body of pond below water filter plate, the discharge outlet of described drainpipe is arranged on above sand bed.
Further, described feed pipe tube wall evenly offers delivery port.
Further, described burial depth is 15 ~ 30cm, and in sand bed, grains of sand diameter is 0.2 ~ 0.5mm.
Further, described bolting silk cloth is 80 mesh sieve silks.
Further, described water filter plate is concrete water filter plate, every 0.25 ㎡ water filter plate is evenly arranged the leaking hole of 50 ~ 100 diameter 1 ~ 2cm, every 2 ㎡ water filter plates is arranged the sleeve pipe of a length 20 ~ 35cm.
Further, the distance bottom described water filter plate and pond body is 10 ~ 30cm, and the distance of the discharge outlet of described water filter plate and drainpipe is 50 ~ 80cm.
The beneficial effects of the utility model are:
Breeding water body, by setting up water filter plate at Chi Tizhong, is divided into two-layer up and down by the utility model; Water filter plate arranges sand bed, and female, male Tachypleus tridentatus is stayed in the water body of upper strata, lays eggs in sand bed; And the grains of sand in sand bed are cleaned in the flowing of upper and lower two-layer water body, reach the effect of sand bed self-cleaning; Meanwhile, air supply pipe, by running through the sleeve pipe air feed of water filter plate, because bubble is light, constantly moves up, and drives water upwards to be flowed by sleeve pipe, then from the downward seepage flow of sand bed, completes circulation, thus reach the object of cleaning sand bed, and increase dissolved oxygen.In a word, the utility model, by the husky environment that improved to spawning pond structure, adds dissolved oxygen simultaneously, improves the fertilized egg survival rate of Tachypleus tridentatus.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the structural representation of the spawning pond of raising Tachypleus tridentatus fertilized egg survival rate of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of the spawning pond of raising Tachypleus tridentatus fertilized egg survival rate of the present utility model, as shown in the figure, the spawning pond of raising Tachypleus tridentatus fertilized egg survival rate of the present utility model, comprise pond body 1, water filter plate 2, for supporting the supporting brick 3 of water filter plate 2, feed pipe 4, drainpipe 5 and air supply pipe 6, described supporting brick 3 is spaced on pond body 1 bottom surface, described water filter plate 2 level is laid on supporting brick 3, described water filter plate 2 is equipped with bolting silk cloth 7, sand bed 8 laid by described bolting silk cloth 7, described water filter plate 2 is provided with leaking hole (not shown in FIG.) and passes vertically through the sleeve pipe 9 of water filter plate 2, insert in sleeve pipe 9 after the gas outlet socket gas stone 10 of described air supply pipe 6, described feed pipe 4 to be laid on bottom pond body 1 below water filter plate 2, the discharge outlet of described drainpipe 5 is arranged on above sand bed 8.
