Abstract
The invention discloses a kind of crab cultivation methods, include the following steps：Pond has been dug, has kept pond bottom smooth；Fence is fixed at pond edge, fence surface is fixed with grid cloth；One layer of mud, and water filling, input disinfectant are laid with to pond bottom；After the completion of to be sterilized, pond is carried out to change water；Water plant and algae are planted in pond；When water plant and algae are capable of providing oxygen enough in pond, juvenile crab is put into pond；Timing launches feed and changes water, and maintains pond water temperature in the range of 10 ~ 30 degrees Celsius；Pond oxygen content in water opens aerator when relatively low, increases oxygen content into water, until crab can be caught.From the foregoing, a kind of crab cultivation method of the invention, the cultural method of structure setting and science by carrying out science to pond keep the survival rate of crab high, and growth rate is fast, and in breeding process, the death rate of crab is low.
Description
Technical field
The present invention relates to the technical fields of crab cultivation, and in particular to a kind of crab cultivation method.
Background technology
Crab is shellfish, and body is protect by hard shell, is breathed by the gill.In taxonomy, it is with shrimp, dragon
Shrimp, hermit crab are species.The crab of most types live in the sea or neritic zone, there are also dwell in fresh water or land
Ground.They lean on female crab next life small crab, and mother crab can all produce many ovum every time, quantity up to millions of grains more than.Crab be according to
Judge direction by earth's magnetic field.This kind of bio-genetic material number is complicated and has prodigious otherness, Chang Duoda more than 100
It is right.Common crab has steamed crab（River crab, eriocheir sinensis, clear water crab）, swimming crab etc..The resource very abundant of China crab, wherein
With the Lake Gucheng steamed crab of THE LOWER YANGTZE VALLEY, Taihu Lake steamed crab, Gaoyou Lake steamed crab, Yangcheng Lake steamed crab, crab building steamed crab, Xinghua
The steamed crab that steamed crab, Hongze lake steamed crab are produced is top grade.
The technology for propagating crab artificially also has many deficiencies, people to be still not perfect the experience of artificial crab farming.And crab
Cultural technique directly affects the survival rate of juvenile crab and the death rate of crab.In addition the temperature environment of various regions is also different, needs
After the growth rhythm of to master crab, to realize that different geographical can cultivate crab.
Invention content
It is an object of the invention to：Overcome the deficiencies of the prior art and provide a kind of crab cultivation method, by pond into
The structure setting of row science and the cultural method of science keep the survival rate of crab high, and growth rate is fast, in breeding process, crab
The death rate it is low.
The technical solution used in the present invention is：
A kind of crab cultivation method, includes the following steps：
1）Pond has been dug, has kept pond bottom smooth；
2）Fence is fixed at pond edge, fence surface is fixed with grid cloth；
3）One layer of mud, and water filling, input disinfectant are laid with to pond bottom；
4）After the completion of to be sterilized, pond is carried out to change water；
5）Water plant and algae are planted in pond；
6）When water plant and algae are capable of providing oxygen enough in pond, juvenile crab is put into pond；
7）Timing launches feed and changes water, and maintains pond water temperature in the range of 10 ~ 30 degrees Celsius；
8）Pond oxygen content in water opens aerator when relatively low, increases oxygen content into water, until crab can be caught.
The beneficial effects of the present invention are：
A kind of crab cultivation method of the present invention, the cultural method of structure setting and science by carrying out science to pond, makes
The survival rate of crab is high, and growth rate is fast, and in breeding process, the death rate of crab is low.
Specific implementation mode：
A kind of crab cultivation method, includes the following steps：
1）Pond has been dug, has kept pond bottom smooth；
2）Fence is fixed at pond edge, fence surface is fixed with grid cloth；
3）One layer of mud, and water filling, input disinfectant are laid with to pond bottom；
4）After the completion of to be sterilized, pond is carried out to change water；
5）Water plant and algae are planted in pond；
6）When water plant and algae are capable of providing oxygen enough in pond, juvenile crab is put into pond；
7）Timing launches feed and changes water, and maintains pond water temperature in the range of 10 ~ 30 degrees Celsius；
8）Pond oxygen content in water opens aerator when relatively low, increases oxygen content into water, until crab can be caught.
