Abstract
Eyebrow foot crab incubating oosperm device is liberated, belongs to technical field of aquaculture, more particularly to a kind of hatching apparatus for being suitable for liberation eyebrow foot crab embryonated egg.It is characterized in that, the frame formed with cross bar, vertical pole and montant（1）, frame is cuboid, the upper end opening of frame, base of frame and has crowded around bolting silk from 5 10 ㎝ frame parts of bottom（2）, etting that the upper end of bolting silk is made into by PVC wire rods（3）Frame surrounding is fixed on, etting is fixed on frame, lower end and bolting silk joint close.The utility model can be lifted directly in another culture pond from a culture pond, conveniently moving, greatly improve efficiency, and parent is not easy to be injured hatchability of fertile eggs height, larger to large-scale liberation eyebrow foot juvenile crab kind production function.
Description
Technical field
The utility model belongs to technical field of aquaculture, more particularly to a kind of to be suitable for incubating for liberation eyebrow foot crab embryonated egg
Makeup is put.
Background technology
It is not real crab class to liberate eyebrow foot crab, and it is different on Marine shoal that it is that a kind of between shrimp crab lives in
Tail class biology, is distributed in Shandong sea area, wild resource amount is extremely limited.For the life of beginning of this century liberation eyebrow foot crab wild stocks
The situation of quantity continuous decrease is deposited, the artificial seed's breeding of liberation eyebrow foot crab has succeeded and reached production scale, and propagation is put
Stream also has been carried out for many years.At present when oogenesis parent during scale breeding goes out young progress cloth pond in incubating oosperm, one
As be that ovigerous crab is put into larval culture pond, when the young that parent incubating oosperm goes out when part reaches requirement density, by parent
Body, which is moved into another sky pond, to be continued to hatch；Or the hatching method with reference to river crab, swimming crab, ovigerous crab is fitted into cylinder mould,
Another pond is moved into from a pond, since liberation eyebrow foot crab morphosis is different from river crab, swimming crab, shell is very thin, moves
Shell breakage is easily lead to during pond, while embryonated egg also comes off seriously, in addition parent is heaped and mutually clamped down on, and makes its appendage easily
Fracture, parent damage is extremely serious, causes the ovigerous crab death rate to raise significantly, while the appendage to come off falls in larval culture bottom of pond
It is difficult to clean up totally, not only increasing workload, it is very big to the water quality impact in larval culture pond together with injured dead parent.
The content of the invention
The purpose of this utility model seeks to provide a kind of new liberation eyebrow foot crab incubating oosperm device, overcomes existing
Deficiency in seed breeding technology during parent incubating oosperm cloth pond, reach cost of manufacture it is cheap, it is pollution-free, reusable,
Reduce the parent injury death rate and improve the purpose of hatchability of fertile eggs.
The liberation eyebrow foot crab incubating oosperm device of the utility model, it is characterised in that there is cross bar, vertical pole and montant structure
Into frame, frame is cuboid；The upper end opening of frame, base of frame and has crowded around sieve from bottom 5-10 ㎝ frame parts
Thin,tough silk, the upper end of bolting silk are fixed on frame surrounding by the etting that PVC wire rods are made into, and etting is fixed on frame, lower end and bolting silk
Joint close.
Further, the cross bar 100-120 ㎝ of said frame, vertical pole 70-90 ㎝, montant 100-140 ㎝.
Further, said frame uses stainless steel, or material that is other nontoxic harder and being not easily broken, with
It will not get rusty in the seawater, the not perishable water quality that also do not interfere with is advisable.
Said frame bottom and crowded around from bottom 5-10 ㎝ frames using 120 mesh sieve thin,tough silk, the upper end of bolting silk is knitted with PVC wire rods
Into etting be fixed on frame surrounding, 0.5~1.0 ㎜ of etting gauge or diameter of wire, 5.0~10 ㎜ of etting bore.
Liberation eyebrow foot crab incubating oosperm device disclosed in the utility model, in use, immersing the water in larval culture pond
In, on base of frame bolting silk upper berth, thin sea sand clean 5-10 ㎜, sea sand need to disinfect in advance.Its good effect major embodiment
：
1st, montant is longer, and more than the depth of water in larval culture pond, vertical pole is shorter, is conducive to move pond operation；
2nd, the upper end opening of frame, easy to the parent for fishing for the parent hatched and addition embryonated egg will hatch；
3rd, it makes raw material and uses the artificial materials such as stainless steel and PVC, simple for production, corrosion-resistant, reusable, and not
Influence water quality；
4th, the utility model can be lifted directly in another culture pond from a culture pond, and conveniently moving, greatly improves labor
Efficiency of movement, and parent is not easy to be injured hatchability of fertile eggs height, it is larger to large-scale liberation eyebrow foot juvenile crab kind production function.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in Figure 1, it is disclosed in the utility model liberation eyebrow foot crab incubating oosperm device, have cross bar, vertical pole and
The frame 1 that montant is formed, frame are cuboid, and 100 ㎝ of cross bar, 80 ㎝ of vertical pole, 120 ㎝ of montant, montant is grown, more than larval culture
The depth of water in pond, vertical pole is short, is conducive to move pond operation, frame uses stainless steel, or other nontoxic harder and not easy to break
Disconnected material, will not get rusty in the seawater, the not perishable water quality that also do not interfere with is principle.
The base of frame of the utility model and 120 mesh sieve thin,tough silk 2 are crowded around from 10 ㎝ frame parts of bottom, bolting silk is made upper end and opened
Mouthful net cage, specification is the ㎝ of long 100 ㎝ × wide 80 ㎝ × 10, is fixed on lower frame, the thin sea sand that parent is hidden is not leaked
To outside frame.
The etting 3 being made into using PVC wire rods, is fixed on the frame surrounding of bolting silk upper end, 0.8 ㎜ of etting gauge or diameter of wire, net
7 ㎜ of bore, lower end and bolting silk joint close, parent is crowded around in frame.
The upper port of frame, the parent of the young will be hatched easy to fish for the parent hatched or be put into embraced embryonated egg
Crab.
It is layered on using clean thin sea sand on base of frame bolting silk, burial depth is 6 ㎜, when in use, is first carried sea sand
Before disinfect, be laid in base of frame.
The utility model first carries out disinfection after bolting silk and etting will be fixed on frame, then completes clean sea sand, will fill
Put in culture pond, culture pond is watered in advance, and the peak level of water should be less than the 5-10 ㎝ of device montant height, make parent
Body will not be gone to outside device, and position of the adjusting apparatus in pond, makes its balance and stability, will not rock or turn upside down, and then will be prepared
The ovigerous crab in cloth pond is put into device, in hatching process, is pulled the parent hatched out at any time, is kept the good water of culture pond
Matter, when parent, which embraces the young quantity that incubating oosperm goes out, reaches the density of culture pond requirement, is lifted hatching apparatus by two people
Go out, move into new pond and continue to hatch, keep balance when device moves as far as possible, prevent sand bed from moving, after Xin Chizhong puts stabilization device,
It is added as needed on parent.After the completion of the cloth pond of workshop, the parent hatched in sand bed is all taken out, by sea sand
Pour out, frame and bolting silk and mesh sheet Integral cleaning are clean, are exposed to the sun under the sun, are put in storage after disinfection, coming year recycling.
