Abstract
A giant spiny frog spawn hatching device comprises ponds and a pipeline with draining holes, wherein the pipeline is arranged above the ponds. Draining pores are evenly formed on the periphery of the upper portion of each pond. A hatching frame floats on the water surface of each pond. By the draining holes formed in the upper portion of each pond, the water on the water surface keeps flow to provide sufficient oxygen, and frog spawn hatching and hatched tadpoles are benefitted. The giant spiny frog spawn hatching device is simple in structure, high in hatching rate and convenient in manual management.
Description
Technical field
The utility model relates to technical field of aquaculture, is specifically related to a kind of hatching apparatus of Ranaspinosa David ovum.
Background technology
Ranaspinosa David is the up-and-coming youngster of China's frog culture industry, is the new focus of increasing peasant income, and development is very fast, promise well.Greatly develop and propagate artificially, Reasonable Protection exploitation, could meet the growing demand of people.In propagating artificially, spawn incubation effect is most important.Chinese patent (application number: 201220267615.7) disclose a kind of Ranaspinosa David frog's egg Artificial Control hatching apparatus, comprised hatching house, be provided with air-conditioner and incubation tank in hatching house, be provided with water inlet and delivery port on described incubation tank; On described water inlet, be provided with temperature sensor, and temperature sensor is connected with air-conditioner.The beneficial effect of this utility model: the utility model is indoor by incubation tank is arranged on, well regulates water temperature by the height of room conditioning actuator temperature, improves the survival rate of the frog.
Spawn incubation rate is only not relevant with the quality of frog's egg itself, the more important thing is that management has close ties with spawn incubation.It is generally acknowledged in spawn incubation process, should reduce hatchery water as far as possible and change speed, allow water store the long period in pond, water temperature is raise, promote the hatching process of the frog.On the other hand, in hatching process, for guaranteeing that spawn incubation has sufficient oxygen.At present, in situation with good conditionsi, can, at pond face device Shower tap, can supply needing of hatching by many direct oxygen injections like this, water spray can not be too urgent, in addition, in the weather rainless in arid, temperature is high, air is dry, and the ovum of the floating water surface is rolled into a ball surperficial glued membrane moisture evaporation, glued membrane hardening becomes fragile, and embryo can be because of dry dead.For avoiding embryo dry dead, the instruments such as available plank, dredger are pressed into floating ovum group in water gently, make ovum group Face Immersion moistening.For addressing the above problem, current spawn incubation device is relatively loaded down with trivial details, and poor effect.
Utility model content
The purpose of this utility model is, solves the problem of the loaded down with trivial details and poor effect of current Ranaspinosa David ovum hatching apparatus.Provide a kind of simple in structure, incubation rate height facilitates again the hatching apparatus of labor management.
The utility model is as follows for solving the problems of the technologies described above adopted technical scheme:
A hatching apparatus for Ranaspinosa David ovum, comprises pond body, and the top of described pond body evenly arranges around pond body one week the aperture leaking, and also floating on the water surface of Chi Tizhong have a hatching frame; Also be included in the pipeline with leaking hole that body top, pond arranges, leak and enter pond body.
For convenience of manual operation, hatching frame is the profile that can bubble through the water column, and framework fixed network bore dia is less than frog's egg gauze.Pond body is that plastic basin just can shift easily and other assemble other annexes on the other hand.Described plastic basin size is 0.3～3m
2.Excessive Chi Tizhong hatching frog's egg, floating the walking about of hatching frame is awkward.
In order better to control current, make flow, further, on the top of pond body, around pond body, the aperture leaking is evenly set for one week.Better mode is to be the pipeline with leaking hole arranging above the body of pond at described water feed apparatus, leaks and enters pond body.Described leaking hole is one group that in water (flow) direction, evenly arranges.The hatching apparatus of one group or more Ranaspinosa David ovum can also be more conveniently set like this,
Because the just tadpole of hatching, physique a little less than, unstable, for the tadpole in hatching ten days, should in described device, continue to cultivate, effect is better also beneficial to management.
The beneficial effects of the utility model are that, by the aperture that evenly setting is leaked on body top, pond, the small tadpole flowing to provide sufficient oxygen to be conducive to spawn incubation and just to have hatched is provided the current of the water surface.The utility model is simple in structure, and incubation rate height facilitates again labor management.
Below in conjunction with embodiment, the utility model is further explained and explanation.
Accompanying drawing explanation
The structural representation of the hatching apparatus of a kind of Ranaspinosa David ovum of Fig. 1
Embodiment
A hatching apparatus for Ranaspinosa David ovum, comprises pond body 1, and the top of described pond body 1 evenly arranges around pond body one week leak little by 2, and also floating on the water surface in pond body 1 have a frame 3 of hatching; Also be included in the pipeline 4 with leaking hole 5 that body 1 top in pond arranges, leak and enter pond body 1.Described pond body 1 is plastic basin, and plastic basin size is 0.3～3m
2.Described leaking hole 5 is one group that in water (flow) direction, evenly arranges.
When incubating tadpole, ovum is put into hatching frame, keep current to provide sufficient oxygen to be conducive to hatching.After hatching, tadpole is Fen Li with unhatched frog's egg.Tadpole after hatching is placed in this device of not hatching frame and continues to raise ten days.
Claims (3)
1. a hatching apparatus for Ranaspinosa David ovum, is characterized in that: comprise pond body (1), the top of described pond body (1) is evenly provided with the aperture (2) leaking for one week around pond body, and also floating on the water surface in pond body (1) have a hatching frame (3); Also be included in the pipeline with leaking hole (5) (4) that pond body (1) top arranges.
2. the hatching apparatus of Ranaspinosa David ovum as claimed in claim 1, is characterized in that: described pond body (1) is plastic basin, and plastic basin size is 0.3～3m
