Abstract
The invention discloses a kind of cray reproduction techniques, comprise the steps of：One, breeding pond is built by cement；Two, before putting close shrimp in a suitable place to breed, per square meter, breeding pond is carried out disinfection with 0.2kg quick limes；Three, physical health, the close shrimp that appendage is complete, bright in colour, body surface is disease-free and injury-free are selected, is launched in annual 6 ~ August part；Four, 5 points of dispensing feeds every afternoon, 1 is pressed by animal fodder and plant feed:1 ratio is launched；Five, adhere to changing water in every 3 ~ 5 days primary；Six, for close shrimp after cultivating after a period of time, there is young shrimp after hatching one month in mate and oviposit；Seven, seedling is placed in cement pit, 200 ~ 250 tails is placed per square meter.The present invention breeds lobster by scientific and reasonable step, and management regulation can effectively ensure that the breeding potential of cray, and hatching rate is up to 90% or more.
Description
Technical field
The present invention relates to a kind of cray reproduction techniques, are applied to crayfish breeding technique field.
Background technology
Cray is economic freshwater shrimps, because meat flavour is delicious wide welcomed by the people, is had become in recent years in China important
Economic breed variety, with the continuous improvement of people's living standards, people are higher and higher to quality of life requirement, to cray
Demand is also constantly increasing, and existing cray reproduction technique majority is using outdoor free-ranging, and management is lack of standardization, and there are crays
The low problem of seedling percent.
Invention content
To solve the problem above-mentioned, the invention discloses a kind of cray reproduction techniques, comprise the steps of：
One, breeding pond is built by cement, breeding bottom of pond area is 4 ~ 5 square metres, and depth is 0.8 ~ 1 meter, bottom of pond asbestos shingle
Artificial nest is built with common brick, breeding adds puggaree at the top of pond；
Two, before putting close shrimp in a suitable place to breed, per square meter, breeding pond is carried out disinfection with 0.2kg quick limes, is dried 3 ~ 5 days after disinfection, is bred water
It is maintained at 0.5 ~ 0.7 meter deeply, puts water hyacinth in pond in a suitable place to breed, aerator is placed on the bank in breeding pond；
Three, select physical health, the close shrimp that appendage is complete, bright in colour, body surface is disease-free and injury-free, individual weight 40g/ tails with
On, the close shrimp of long-distance transport needs first to impregnate 3 ~ 5 minutes in breeding pond, and pool side is placed on 2 minutes pulling out, 3 times repeatedly, then edge
Breeding pool side is slowly put into, and close shrimp 40 ~ 45 is put per square meter, and female-male proportion is consistent, is launched in annual 6 ~ August part；
Four, 5 points of dispensing feeds every afternoon, 1 is pressed by animal fodder and plant feed:1 ratio is launched, and animality is raised
Material selection minced fillet, tankage, plant feed select dregs of beans, bran；
Five, adhere to changing within every 3 ~ 5 days water primary, inspect periodically, when water quality is poor, to drain water in time, cleaning breeding pond, together
When ensure breeding pond in dissolved oxygen amount be 5.8 ~ 6.2mg/L, it is insufficient then open aerator be oxygenated；
Six, after cultivating after a period of time, there is young shrimp, collects seedling in time close shrimp after hatching one month in mate and oviposit；
Seven, seedling is placed on 20 ~ 40 square metres of area, in deep 1 meter of cement pit, 200 ~ 250 tails is placed per square meter.
Using the technical program, the beneficial effects of the invention are as follows：Lobster, management rule are bred by scientific and reasonable step
Model can effectively ensure that the breeding potential of cray, and hatching rate is up to 90% or more.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Specific embodiment is closed, the present invention is further explained.
The invention discloses a kind of cray reproduction techniques, comprise the steps of：
One, breeding pond is built by cement, breeding bottom of pond area is 4 ~ 5 square metres, and depth is 0.8 ~ 1 meter, bottom of pond asbestos shingle
Artificial nest is built with common brick, breeding adds puggaree at the top of pond；
Two, before putting close shrimp in a suitable place to breed, per square meter, breeding pond is carried out disinfection with 0.2kg quick limes, is dried 3 ~ 5 days after disinfection, is bred water
It is maintained at 0.5 ~ 0.7 meter deeply, puts water hyacinth in pond in a suitable place to breed, aerator is placed on the bank in breeding pond；
Three, select physical health, the close shrimp that appendage is complete, bright in colour, body surface is disease-free and injury-free, individual weight 40g/ tails with
On, the close shrimp of long-distance transport needs first to impregnate 3 ~ 5 minutes in breeding pond, and pool side is placed on 2 minutes pulling out, 3 times repeatedly, then edge
Breeding pool side is slowly put into, and close shrimp 40 ~ 45 is put per square meter, and female-male proportion is consistent, is launched in annual 6 ~ August part；
Four, 5 points of dispensing feeds every afternoon, 1 is pressed by animal fodder and plant feed:1 ratio is launched, and animality is raised
Material selection minced fillet, tankage, plant feed select dregs of beans, bran；
Five, adhere to changing within every 3 ~ 5 days water primary, inspect periodically, when water quality is poor, to drain water in time, cleaning breeding pond, together
When ensure breeding pond in dissolved oxygen amount be 5.8 ~ 6.2mg/L, it is insufficient then open aerator be oxygenated；
Six, after cultivating after a period of time, there is young shrimp, collects seedling in time close shrimp after hatching one month in mate and oviposit；
Seven, seedling is placed on 20 ~ 40 square metres of area, in deep 1 meter of cement pit, 200 ~ 250 tails is placed per square meter.
Finally it should be noted that：Above example is only to illustrate the present invention and not limits technology described in the invention
Scheme；Therefore, although this specification with reference to above-mentioned each embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent replacement；And all do not depart from this
The technical solution of the spirit and scope of invention and its improvement should all be covered in scope of the presently claimed invention.
