Abstract

The utility model relates to the field of rana spinosa cultivation, in particular to a pan-bottom type culture pond for rana spinosa tadpole metamorphosis. The pan-bottom type culture pond comprises apond body, a water inlet and a water outlet. The pond body comprises an opening, a side wall and a pond bottom which is conical; the water outlet is arranged at the center of the conical pond bottom;and the water inlet is arranged above the side wall. Preferably, the opening is square with round corners. The pan-bottom type culture pond has the beneficial effects that: (1) the sewage discharge performance is good, the water takes away the remnant baits and dirt through the pan-bottom type water flow rotation after flowing into the pond, and the water is always kept clean to be beneficial forthe tadpole metamorphosis; (2) the tadpoles go ashore at multiple directions and are not easily dead owing to inhaled water in metamorphosis, the tadpoles are difficult to get sick, the metamorphosissuccess ratio is improved, and the metamorphosis ratio is over 90%; (3) through the pan-bottom type water discharge, the sewage sinks at the bottom, the sewage is discharged at the bottom and the upper part is always kept clean; (4) the water flows flexibly after flowing into the pond, the dead angle does not exist, and ammonia nitrogen and bacteria are not easily generated; and (5) the labor intensity is reduced, and a single worker can manage the metamorphosis of 50, 000 tadpoles.

Description

The abnormal pond of culturing of a kind of pot bottom type stone frog tadpole

Technical field

The utility model relates to the stone frog cultures, the abnormal pond of culturing of especially a kind of pot bottom type stone frog tadpole.

Background technology

The metamorphosis of stone frog tadpole is one of key technology of stone frog breed, and what adopt at present is the abnormal pond of square stone frog tadpole, and as depicted in figs. 1 and 2, opening is a rectangle, is the slope at the bottom of the pond, and water inlet is located at the shallow water upper lateral part, and delivery port is located at the deep water side bottom.Since the blowdown poor performance, easy anoxic, water body does not circulate, and the water of square pool Chi Jiao forms the dead angle, and tadpole is built collection, causes bottom froglet death by suffocation; Breed bacteria and residual dirty the accumulation produce ammonia nitrogen easily, reduce tadpole immunity and attacked by pathogene; Abnormal inconvenient, the water of choking easily causes froglet deformity even dead after the pathology.In a word, the abnormal success rate of tadpole is low, has only 30-40%.In addition, this square pond labour intensity is big, and single labour only can manage the metamorphosis of 1.5 ten thousand tadpoles.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of blowdown performance good, and the abnormal success rate height of tadpole is saved labour's the abnormal pond of culturing of pot bottom type stone frog tadpole.

The utility model solves the technical scheme that its technical problem adopts: the abnormal pond of culturing of this pot bottom type stone frog tadpole, form by pond body, water inlet, delivery port, the pond body comprises opening, sidewall, at the bottom of the pond, be conical at the bottom of the described pond, the center is provided with delivery port at the bottom of the conical pond, and the sidewall top is provided with water inlet.

As preferably, described opening is have fillet square.

The effect that the utility model is useful is: one, blowdown performance is good, and water passes through the rotation that pot bottom type water flows after entering the pond, takes away residual bait dirt, makes water remain cleaning, helps tadpole metamorphosis; Multi-faceted disembarkation was difficult for choking water and death is difficult for falling ill when two, tadpole was abnormal, improved abnormal success rate, and distortion ratio is more than 90%; Three, by the pot bottom type draining, make sewage be sunken to the bottom, keep bottom blow-down and top is cleaned all the time; Four, water flows flexibly after entering the pond, does not deposit the dead angle, is difficult for producing ammonia nitrogen and bacterium; Five, labour intensity alleviates, and single workman can manage the metamorphosis of 50,000 tadpoles.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Embodiment: the abnormal pond of culturing of this pot bottom type stone frog tadpole, as Fig. 3,4, the opening 1-1 of pond body 1 is the square of four fillets, for fillet is to flow flexibly, does not have the dead angle all around after making water enter the pond, 1-3 is conical at the bottom of the pond, shallow just, middle dark shape, conical center just bosom is provided with delivery port 3, the top of sidewall 1-2 is provided with water inlet 2, carries out the edge and drips.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
