Description
Technical field
The utility model relates to the animal-breeding device, particularly at the cultivator of shrimps, fish or crab class.
Background technology
At present, the cultured area of shrimps, fish or crab class enlarges rapidly, and particularly Environment of Litopenaeus vannamei Low is not only cultured in the coastal area, through progressively desalination, can also arrive the inland and propagate artificially with pure fresh water.Propagating artificially with incubation equipment of prior art mainly contains three parts composition, that is: water inlet system, hatching pail and filtration drainage system.In the hatching process,, fertilized egg is constantly moved up and down under the effect of current in bucket by the water inlet of water inlet and the water outlet of delivery port, neither can be deposited to the bottom and death by suffocation can obtain the hatching.Yet existing scheme can not effectively be screened unfertilized or developmental deformity ovum.
In fact, if unfertilized and ovum developmental deformity can not effectively screen, tend to enter the shrimp seed rearing link, this not only has influence on technical staff's judgement, also directly cause the water quality deterioration consequence, and then have influence on the growth rate and the emergence rate of shrimp seedling, influenced greatly and cultured the productivity effect of growing seedlings.Thereby find the way that can effectively remove unfertilized and lopsided dead ovum, be to improve one of key factor of cultivating shrimp seedling quality at present.Same, to other shrimps kind, or the larya culturing of fish or crab class also faces identical problem.
The utility model content
The purpose of this utility model provides a kind of can effectively the screening unfertilized or developmental deformity ovum, and is simple, practical, efficiently at the hatching apparatus of shrimps, fish or the crab class young.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of hatching apparatus at shrimps, fish or the crab class young comprises first incubation vessel, second incubation vessel; Described first incubation vessel bottom is provided with water feed apparatus, is provided with first screen pack of filtered water inlet in first incubation vessel, is connected the mozzle that can guide water to flow to second incubation vessel from first incubation vessel between the first incubation vessel top and second incubation vessel; Be provided with in described second incubation vessel and filter second screen pack that imports water, second incubation vessel bottom is provided with drainage arrangement.
Further, two parts ratio was 3: 1～4: 1 position about described first screen pack was located in first incubation vessel; Two parts ratio was 5: 1～6: 1 position about described second screen pack was located in second incubation vessel.
Further, the order scope of counting of described first screen pack and second screen pack is 250～300 orders.
Further, first incubation vessel and second incubation vessel are provided with gas tube.
Further, described water feed apparatus is the water inlet of the bottom sides setting of first incubation vessel; The described first incubation vessel top-side is provided with delivery port, and outlet pipe one end connects delivery port, and the outlet pipe other end is located in second incubation vessel and is positioned at the second screen pack top, and the top of first incubation vessel is than the high 20～30cm in the top of second incubation vessel.
Further, described drainage arrangement is the second incubation vessel bottom notch, and described second incubation vessel is located in the drain vessel, and the top of second incubation vessel is higher than the top of described drain vessel.
Further, the top of second incubation vessel (2) is than the high 5～10cm in top of drain vessel (8).
The utility model compared with prior art has following distinguishing feature: at first, flow into the thermostatted water of preheating from the water inlet of first incubation vessel bottom, the first incubation vessel first half activity that the fertilized egg of cultivated animals separates at first screen pack earlier, when the water spill-over, energetic, the normotrophic young just flows to second incubation vessel by the delivery port of the first incubation vessel upper side through mozzle along with current, and those are unfertilized, developmental deformity, all will being left on first incubation vessel of vigor difference and being eliminated.Energetic, the normotrophic young then continues to grow at second incubation vessel.Secondly, second incubation vessel bottom is a breach, and unnecessary water flows into drain vessel by breach, and the discarded object of discharging in the paedomorphosis process is taken away, and keeps water quality pure and fresh, makes at one's best all the time to the extraneous physical and chemical factor of paedomorphosis.At last, realize that technology of the present utility model is simple, available bucket and rubber catheter are realized, and be simple and low-cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Fig. 1 is a structural representation of the present utility model.A kind of hatching apparatus at shrimps, fish or the crab class young comprises first incubation vessel, 1, the second incubation vessel 2; The bottom sides of described first incubation vessel 1 is provided with water feed apparatus 3, and water feed apparatus 3 is a water inlet, and water inlet is two in the specific embodiment.In first incubation vessel 1 up and down two parts ratio be that the order scope of counting that 3: 1～4: 1 position is provided with first screen pack, 4, the first screen packs 4 is 250～300 orders.
In the breeding process, the thermostatted water of preheating enters from water feed apparatus 3, and the fertilized egg of cultivated animals is placed on the first half of first incubation vessel 1 that first screen pack 4 separates.
Be connected mozzle 5 between first incubation vessel, 1 top and second incubation vessel 2; When the thermostatted water of preheating arrives first incubation vessel, 1 top, will flow into second incubation vessel 2 by mozzle 5.In the specific embodiment, first incubation vessel, 1 top-side is provided with delivery port, outlet pipe 5 one ends connect delivery port, outlet pipe 5 other ends are located in second incubation vessel 2 and are positioned at second screen pack, 6 tops, the top of first incubation vessel 1 is than the high 20～30cm in the top of second incubation vessel 2, and current flow into second incubation vessel 2 by this height fall.
