The invention discloses a kind of protecting method of freshwater shrimp breeding, comprise the steps：（1）Many pond conservations：A breed parent shrimp is only put in a suitable place to breed in a conservation area of setting, with multiple parallel ponds, separately special pond carries out cultivation and the conservation of parent shrimp；（2）Strict isolation：Pond for conservation need to strictly clean up the pond the solarization pool, and Inlet and outlet water bolting silk net strictly filters；（3）Parent selects：Annual mating period, select big specification, physique healthy and strong, active strong, the disease-free individuality without deformity as parent shrimp, passed on；（4）Parent exchanges：Exchanged between pond is carried out after select parent；（5）Germplasm is monitored：During conservation, expansion are numerous, kind of a quality detection is periodically carried out to breeding by the variety standard of related breeding or the specific variety standard of improved seeds, it is underproof to eliminate in time, to ensure that germplasm does not mix.By a series of above-mentioned technical measures, do not degenerated with the germplasm for ensuring freshwater shrimp breeding, and increase.
Description
Technical field
The invention belongs to technical field of aquaculture, more particularly to a kind of protecting method of freshwater shrimp breeding.
Background technology
Freshwater shrimp (Macrobrachium nipponense), scientific name Macrobrachium nipponensis is commonly called as river prawn, lake shrimp.Its fine and tender taste,
It is delicious flavour, nutritious, it is the deep rare aquatic products liked by broad masses, it is also the important freshwater aquiculture shrimps of China.
More than 20 ten thousand tons of current China's shrimp culture annual production, but also increasing year by year.But it is intensive with the continuous expansion of cultivation scale
There is serious variety deterioration phenomenon in the continuous improvement of change degree, freshwater shrimp, seriously constrains the development of shrimp culture industry.Chinese Fishery
Domestic and international first freshwater shrimps and crabs class new varieties are cultivated through studying for many years in research institute's fresh water fishery research center --- it is miscellaneous
Hand over freshwater shrimp " Taihu Lake 1 " and some excellent strains.Demonstration cultivation proves that its economic characters is excellent, increase production and improve productivity notable.Due to this
A little improved seeds（System）Life-span only 1 year or so as common freshwater shrimp, is required for passage every year, in order to be kept in succeeding generations
Its proterties does not fail, and increases, the invention is characterized in that a series of technical measures have reached preferable effect.
The content of the invention
The invention aims to prevent freshwater shrimp improved seeds（System）Degenerated in passage, for shrimp culture industry provides height
The seed of quality, ensures that the smooth popularization of freshwater shrimp breeding and the healthy stable development of shrimp culture industry provide a kind of freshwater shrimp breeding
Protecting method.
The present invention to achieve the above object, is adopted the following technical scheme that：
A kind of protecting method of freshwater shrimp breeding, it is characterised in that comprise the steps：
（1）Many pond conservations：Conservation area is set up, a breed parent shrimp is only put in a suitable place to breed in a conservation area of setting, with multiple
Separately special pond carries out cultivation and the conservation of parent shrimp in parallel pond；
（2）Strict isolation：Pond for conservation need to strictly clean up the pond the solarization pool, and Inlet and outlet water bolting silk net strictly filters, and prevents wild miscellaneous
Shrimp is mixed into or the outflow of parent shrimp；
（3）Parent selects：Annual mating period, select big specification, physique healthy and strong, active strong, the disease-free individual work without deformity
It is parent shrimp, is passed on；
（4）Parent exchanges：Exchanged between pond is carried out after select parent, i.e., each conservation pond is drawn from another conservation pond
Enter part parent shrimp, bred again after mixing with this pond parent shrimp, and different year is introduced from different conservation ponds, is kept away
Exempt from the repetition in several years of same conservation pond to be introduced from a certain conservation pond；
（5）Germplasm is monitored：During conservation, expansion are numerous, by the variety standard or the specific germplasm mark of improved seeds of related breeding
The certainly phase carries out kind of a quality detection to breeding, underproof to eliminate in time, to ensure that germplasm does not mix.
Preferably：The step（1）In parallel pond quantity be more than 5.
The step（2）Described in bolting silk net mesh number be 80 mesh.
The step（3）Middle parent shrimp selection standard is male more than shrimp 5.0cm, female more than shrimp 4.0cm.
The step（4）In from other conservation ponds introduce parent shrimp quantity be the 30% of this pond parent's shrimp quantity.
Freshwater shrimp breeding protecting method of the invention, mainly selected by including many pond conservations, strict isolation, parent,
A series of technical measures such as parent exchanges, germplasm monitoring, are not degenerated, and increase with the germplasm for ensuring freshwater shrimp breeding.
Specific embodiment
A kind of freshwater shrimp breeding protecting method, comprises the following steps：
1st, many pond conservations：In breeding freshwater shrimp conservation, conservation area is specially set up, only allowed in a conservation area of setting
Put a kind in a suitable place to breed（System）, with the parallel ponds of more than 5, separately special pond carries out cultivation and the conservation of parent shrimp.
2nd, strict isolation：Pond for conservation need to strictly clean up the pond the solarization pool, and Inlet and outlet water strictly filters with 80 mesh sieve tulles, anti-
Only wild miscellaneous shrimp is mixed into or parent's outflow.
3rd, parent selects：Annual mating period, selection specification is big（Male more than shrimp 5.0CM, female more than shrimp 4.0CM）, constitution
Healthy and strong, active strong, the disease-free individuality without deformity is passed on as parent.
4th, parent exchanges：Exchanged between pond is carried out after select parent, i.e., each conservation pond is from another conservation pond
The parent of this pond parental number 30% is introduced on the pool, is bred again after mixing with this pond parent, and different year is from different
Introduce in conservation pond, it is to avoid repeat to be introduced from a certain conservation pond.
5th, germplasm monitoring：During conservation, expansion are numerous, the kind of the related breeding passed through by national original breeding validation board
Matter standard or improved seeds（System）Specific variety standard periodically carry out kind of a quality detection to breeding, it is underproof to eliminate in time, with
Ensure that germplasm does not mix.
Further the present invention is elaborated below by specific embodiment.
Embodiment 1
Certain provincial freshwater shrimp seed multiplication farm, with freshwater shrimp breeding protecting method of the invention, is carried out miscellaneous in the conservation area of special setting
Freshwater shrimp " Taihu Lake 1 " improved Varieties conservation is handed over, separately special pond carries out cultivation and the conservation of parent shrimp with 7 parallel ponds.With
Need to strictly be cleaned up the pond in the pond of conservation and shine the pool, Inlet and outlet water is strictly filtered with 80 mesh sieve tulles casees, prevents wild miscellaneous shrimp to be mixed into or parent
Outflow.Annual mating period, select big specification, physique healthy and strong, active strong, the disease-free individuality without deformity as parent, carry out
Passage, while the parent carried out between different conservation ponds exchanges.During conservation, expansion are numerous, by national original breeding authorization committee member
The variety standard of the hybridization freshwater shrimp " Taihu Lake 1 " that can pass through periodically carries out kind of a quality detection, underproof to eliminate in time, to ensure to plant
Matter does not mix.By a series of above-mentioned preservable measures, the excellent economic characters of hybridization freshwater shrimp " Taihu Lake 1 " are made to be maintained, and
Increase.
