Growing pool inner water position is 12-15cm, is provided with filter screen at the inlet and outlet of the aquaculture pond；
(2), the disinfection of aquaculture pond: carrying out dredging to pond before cultivation water filling, rinse and be exposed to the sun, and every 5 days with life
Lime carries out disinfection processing to aquaculture pond, and surrounding plants water plant in aquaculture pond, and water vegetal cover face is the aquaculture pond water surface
One third；
(3) Water-quality control: aquaculture pond water PH is maintained between 6.5-7.5, and aquaculture pond water temperature is maintained at 18-24 DEG C, pond
Water clarity is controlled at 30-40 centimetres or more；
(4), seed prepares before cultivating: 3500-4500 tail per acre, shrimp seedling weighs about 150 tails/jin, while launching 5-15 per acre
Tailed silver carp is selected not with pathogen, the cray seedling that body colour is normal, appendage is complete, is launched into water body；It keeps daily
Aerator oxygenation in 1.5-2 hours；Weather has the oxygenation time for increasing aerator when change；
(5), the cultivation of shrimp seedling: cray special feed is launched to aquaculture pond, it is morning respectively that feed part is launched twice
6-7 point and evening 6-7 point, putting seedling initial stage will pinpoint and launch feed around in water plant, launch and be accustomed to once all left and right shrimp
Property be gathered in water plant around to climb and ingest, respectively feed intake sooner or later daily primary, only throw a feed daily to August part.
This method is further, and the time for launching shrimp seedling is annual April or May.
This method is further, and during the cultivation of the shrimp seedling, day is 0.015%-0.025% with concentration every other week
Dehydroacetic acid sodium water solution rinse a cray.
This method is further, and the evening feeding volume accounts for the 75-85% of day feeding volume, and daily feeding amount is Chi Zhong little
The 3-5% of lobster weight.
This method is further, and the water plant includes eel grass, water peanut, Ye Heizao, Eichhornia crassipes, water lettuce, sea
It is one or more kinds of in algae, bog pondweed.
Beneficial effects of the present invention: it is carried out disinfection processing using quick lime is launched into pond, can guarantee the product of cray
Matter, it is Fresh & Tender in Texture, nuisanceless, food safety quality is further increased, and enhance the autoimmunity and resistance of cray；
And put in aquaculture pond equipped with aerating machine, water plant is planted in water, can not only keep the oxygen content in water, moreover it is possible to purified water
Matter, to improve the survival rate of cray；It can promote cray healthy growth, and reduce the disease incidence of cray,
Improve yield.
Detailed description of the invention
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be in embodiment
Required attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the invention
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is a kind of flow chart of the cultural method embodiment of cray according to an embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art's every other embodiment obtained belong to what the present invention protected
Range.
In the following, making further description to the present invention in conjunction with attached drawing and specific embodiment:
Referring to Fig. 1, a kind of cultural method of cray according to an embodiment of the present invention, it is characterised in that: its specific side
Method is as follows:
The selection of S101 aquaculture pond: selection pond depth 0.8-1m, in pond, surrounding arranges high 50 centimetres of escaping-preventing facilities, supports
