Description
Technical field
A kind of blue crab cultivation device is the utility model is related to, is specifically related to a kind of mud crab spawning sand table.
Background technology
With the progress of aquaculture technology and the continuous development of cultivation scale, blue crab cultivation amount increases year by year, but at present
The seed of most of cultivation mud crabs derives from natural waterses, wild natural seed is caught on a large scale, to the natural money of mud crab
Source causes great destruction, the sustainable development of serious threat mud crab wild resource.
Research process are bred in mud crab seedlings over the past thirty years, researcher has used kinds of experiments method to improve
The egg laying amount and egg load of mud crab, such as excision optic stalk, dry dew stimulation, fortification etc., the egg laying amount and egg load of mud crab are
Produce the prerequisite of seed quantity.It is always to promote the effective measures of mud crab spawning to cut off optic stalk and dry dew stimulation, can
So that the time needed for spawning is greatly shortened, aquaculture cost is reduced.But past mud crab is bred typically in large-scale cement pond, soil
Pond is carried out, egg laying amount and egg load number had a strong impact on by breeding environment and substrate, cause relatively low egg laying rate of red swamp and
Higher abortion ratio, and ovigerous crab is not easy to realize and remove hatched in time.With the progress of room heat source technology, with
And the foundation of visual cultivating system, the research that mud crab breeds enter again flouring period.Indoors in artificial breeding,
Visualization and highly controllable breeding environment greatly reduce the limitation to mud crab spawning, and then improve egg laying amount and oogenesis
Amount, this is the maximum difference of traditional outdoor nursery and indoor raising of seedling.It is used for mud crab spawning in indoor circulating water cultivation system
Substrate is more difficult to be laid and easily goes bad, and causes mud crab abortion ratio higher in breeding.Indoor circulation cultivating system seedling-raising technique
Can be excellent, but be but unable to extensive development, reason is the complicated of circulating water culture system, the foundation of cultivating system and
Maintenance cost remains high.
Therefore, a kind of efficient and easy mud crab spawning sand table is urgently studied.
Utility model content
The utility model devises a kind of mud crab spawning sand table in view of the shortcomings of the prior art.
The utility model is realizes object above, using following scheme：A kind of mud crab spawning sand table, including upper opening
Box body, the box body middle part are provided with horizontal stand, the box body are divided into two parts up and down, the horizontal stand lower section is solid
Surely gas stone is connected with, is equipped with plastic wire panel on the horizontal stand successively from the bottom to top, the plastic wire panel upper berth is set
There is husky net, the sand is online to be equipped with sand bed, and the horizontal stand is hollow-core construction and is connected with an escape pipe, the escape pipe
An air inlet pipe is inside provided with, one end of the air inlet pipe passes from the horizontal stand and is connected in the gas stone, and its is another
End is stretched out the escape pipe and is connected with an oxygen pump, and the horizontal stand bottom is provided with some through holes.
Further, nylon syringe filter and air valve, nylon syringe filter are additionally provided between the air inlet pipe and oxygen pump
For impurity screening, air valve is used to adjust air inlet size.
Further, the horizontal stand is made up of pvc pipe, stabilization firm in structure and low manufacture cost.
Further, the escape pipe includes vertical section and bending section, and the vertical section is perpendicular to the horizontal stand, institute
State bending section to stretch out to the box portion outside, be easy to the water of box body bottom discharging box portion outside.
Further, the escape pipe is made up of pvc pipe.
Compared to the prior art the utility model, has the following advantages that and beneficial effect：Oxygen is passed through by air inlet pipe, and
Water from escape pipe discharge box body bottom, the water above box body enter box body bottom by Action of Gravity Field through sand bed, can be effective
The sand bed bottom that makes be in higher dissolved oxygen state, ensure the clean of sand bed sand, there is provided clean suitable mud crab spawning place
And habitat, reach the purpose for effectively improving mud crab egg laying rate of red swamp, it is further provided mud crab seedling yield.

Embodiment
With reference to Fig. 1 to Fig. 5, a kind of mud crab lays eggs sand table, includes the box body 1 of upper opening, it is characterised in that：The box body
1 middle part is provided with horizontal stand 2, the box body 1 is divided into two parts up and down, the lower section of horizontal stand 2 is fixedly connected with
Gas stone 3, plastic wire panel 4 is equipped with successively from the bottom to top on the horizontal stand 2, sand is equipped with the plastic wire panel 4
Net 5, sand bed 6 is equipped with the husky net 5, and the horizontal stand 2 is hollow-core construction and is connected with an escape pipe 7, the outlet
An air inlet pipe 8 is provided with pipe 7, one end of the air inlet pipe 8 passes from the horizontal stand 2 and is connected in the gas stone 3,
Its other end stretches out the escape pipe 7 and is connected with an oxygen pump, and the bottom of horizontal stand 2 is provided with some through holes 21, through hole 21
Aperture be preferably 5mm.
As shown in figure 1, being additionally provided with nylon syringe filter 81 and air valve 82 between the air inlet pipe 8 and oxygen pump, air inlet pipe 8 can
To use common flexible pipe, its diameter is less than escape pipe 7.The horizontal stand 2 is made up of pvc pipe.As shown in Figure 1 and Figure 4, institute
Stating escape pipe 7 includes vertical section and bending section, and the vertical section is perpendicular to the horizontal stand 2, and the bending section is to the box
The outside of body 1 is stretched out.The escape pipe 7 is made up of pvc pipe.Whole support can be made up of PVC, including pvc pipe, elbow,
