Abstract

The utility model provides an optimal selecting device of primary hatched zoeae of charybdis feriatus, and belongs to an artificial breeding device of the charybdis feriatus. The optimal selecting device of the primary hatched zoeae of the charybdis feriatus can be used for removing dead eggs, dead primary hatched zoeae, malformation and weak primary hatched zoeae conveniently, and separating the dead eggs, the dead primary hatched zoeae, the malformation and weak primary hatched zoeae from high quality primary hatched zoeae. According to the technical scheme, a hatching barrel, a heating bar, an incandescent light bulb, a sunshade net and air exhausting stone are included, and a water outlet and a valve are arranged on the bottom of the hatching barrel. The optimal selecting device of the primary hatched zoeae of the charybdis feriatus is characterized in that the height of the barrel wall of the hatching barrel is 1.2m, the volume of the hatching barrel is 0.6m<3>, the heating bar and the air exhausting stone are placed in the hatching barrel, the 150W incandescent light bulb is hung at the position, 30cm away from an upper edge opening of the hatching barrel, and the sunshade net is paved on the upper edge opening of the hatching barrel.

Description

A kind of Xiu Ban Charybdis is just incubated the excellent device of selecting of zoea

Technical field

The utility model belongs to the device that Xiu Ban Charybdis artificial breeding is used.

Background technology

Xiu Ban Charybdis (Charybdis feriatus) is the higher large-scale sea crabs class of a kind of economic worth, mainly is distributed in southern East China Sea and South China Sea in China.Xiu Ban Charybdis delicious meat, mouthfeel be good, be of high nutritive value, individual large, color red gorgeous, be regarded as high-grade precious marine product, the market price one is to high.At present, the commodity crab overwhelming majority of selling on market derives from natural sea area, and due to the change of overfishing and briny environment, rust spot Charybdis wild resource is damaged, and Population and catch descend year by year.Therefore, the artificial seed who carries out rust spot Charybdis breeds research, and is significant to promoting the wild resource protection and alleviating relation between market supply and demand.

In the work of Xiu Ban Charybdis artificial breeding, the quality of just incubating zoea is to obtain the successful most important factor of growing seedlings.Xiu Ban Charybdis ovigerous crab is in the artificial incubation process at present, the excellent method and apparatus of selecting of zoea is improper owing to just incubating, even the young is not selected excellent, first be mixed with dead ovum and the unsound lopsided idiosome that much carries disease germs in incubating zoea and make what collect, thereby it is higher to produce the first zoea lethality of incubating, later stage zoea distortion ratio and the problems such as success rate is lower of growing seedlings.Therefore, need that design is a kind of is convenient to remove dead ovum, the dead first first zoea of incubating of incubating zoea, deformity and tender constitution, itself and high-quality are just incubated Xiu Ban Charybdis that zoea separates just incubate zoea and select excellent device.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of be convenient to remove dead ovum, the dead first first zoea of incubating of incubating zoea, deformity and tender constitution, itself and high-quality is just incubated Xiu Ban Charybdis that zoea separates just incubate zoea and select excellent device.

The technical solution of the utility model adopts hatching pail, heating rod, incandescent lamp, sunshade net, gas exhausting stone, and the bottom of hatching pail arranges a delivery port and valve, it is characterized in that the bucket wall height of hatching pail is 1.2m, and volume is 0.6m ³, heating rod and gas exhausting stone are placed on inside hatching pail, hang the incandescent lamp of a 150W in distance hatching pail upper edge hole 30cm height part, bedding sunshade net above the upper edge hole of hatching pail.

The utility model has following beneficial effect compared to existing technology: the one, and reasonable in design, easily manufactured, be easy to apply in the work of Xiu Ban Charybdis artificial breeding; The 2nd, utilize this device can regulate and control water temperature, oxygen and intensity of illumination, be beneficial to the female parent of rust spot Charybdis and normally successfully hatch the first zoea of incubating; The 3rd, utilize this device easily healthy, the well-developed zoea of just incubating to be separated with the first first zoea of incubating of incubating zoea, deformity and tender constitution of dead ovum, death rapidly, through select excellent after, the ratio that high-quality is just incubated zoea can reach more than 95%, far above the ratio of present common collection mode gained; The 4th, utilize this device staff that can conveniently grow seedlings correctly to count, and can according to growing seedlings demand, in a planned way use high-quality just to incubate zoea quantity.

Embodiment

It is 1.2m that the utility model (referring to accompanying drawing) adopts the bucket wall height of hatching pail 1, and volume is 0.6m ³, the bottom of hatching pail arranges a delivery port 6 and valve 7, and heating rod 2 and gas exhausting stone 5 are placed on inside hatching pail, hang the incandescent lamp 3 of a 150W in distance hatching pail upper edge hole 30cm height part, bedding sunshade net 4 above the upper edge hole of hatching pail.when the utility model uses, first inject 0.5m in hatching pail ﹠lt, sup TranNum="76" ﹠gt, 3 ﹠lt, /sup ﹠gt, cleaning natural sea-water through the sand filter, the oxygenation in the seawater in the hatching pail by gas exhausting stone subsequently, open simultaneously heating rod, control water temperature and remain on 28 ℃, move into Xiu Ban Charybdis ovigerous crab in hatching pail from cultivate the pond, then bedding sunshade net above the upper edge hole of hatching pail, control the interior intensity of illumination of hatching pail lower than 100Lx, be beneficial to the normal hatching smoothly of fertilized egg of ovigerous crab, after treating to incubate zoea at the beginning of ovigerous crab is hatched, pull Xiu Ban Charybdis parent out, remove sunshade net, close heating rod, open simultaneously incandescent lamp, and close oxygen increasing pump, make and stop oxygenation in hatching pail, after standing 20 minutes, make stalwartness, the well-developed zoea light floating that becomes in hydrostatic of just incubating, be distributed in the top layer of hatching pail maritime interior waters, and make dead ovum, the dead first zoea of incubating, deformity and tender constitution first incubate the bottom that zoea sinks down into hatching pail, then with the dead ovum of hatching pail bottom, the dead first zoea of incubating, deformity and tender constitution first incubate zoea and dirt absorption, again toward the interior micro-oxygenation of hatching pail, make a barrel interior high-quality just incubate the zoea Uniform Dispersion, be convenient to the first zoea of incubating in hatching pail is counted, according to the requirement of the plan of growing seedlings to young quantity and density, high-quality is just incubated all or part of immigration nursery pond of zoea grows seedlings.

Claims

1. the spot Charybdis that becomes rusty is just incubated the excellent device of selecting of zoea, adopts hatching pail, heating rod, incandescent lamp, sunshade net, gas exhausting stone, and the bottom of hatching pail arranges a delivery port and valve, it is characterized in that the bucket wall height of hatching pail is 1.2m, and volume is 0.6m ³, heating rod and gas exhausting stone are placed on inside hatching pail, hang the incandescent lamp of a 150W in distance hatching pail upper edge hole 30cm height part, bedding sunshade net above the upper edge hole of hatching pail.
