Description
Technical field
The present invention relates to the cultivating systems and cultural method under a kind of prawn breeding early stage different family common environmentals, belong to
Prawn breeding technical field.
Background technology
Prawn is one of main aquaculture kind in China.In order to further improve the yield of prawn and quality, both at home and abroad
Genetic improvement is carried out to the prawn kind of current cultivation.The selection and breeding of improved seeds are the effective of improvement prawn important economical trait
Means establish family on a large scale, using pedigrees such as individual itself, compatriot, ancestors and offsprings and measure information, very big by constraining
Likelihood method (restricted maximum likelihood, REML) and optimal linear unbiased prediction method (best linear
Unbiased prediction, BLUP) carry out Genetic Evaluation, reserve seed for planting parent according to multiple selection index selection, gradually into
For a kind of important method of aquatic livestock selection and use, what the extensive family selective breeding technology based on mark auxiliary carried out prawn
Genetic improvement is at home and abroad carried out extensively.
During the extensive family selective breeding of prawn, first with directional cross technology, established by Nested Design complete same
Born of the same parents and family half sibs since each family individual is smaller, can not be marked, it is necessary to individually be hatched to each family without section children
Body is cultivated and arrives the young shrimps of long 1cm of body or so, and young shrimp is further continued for the independent juvenile prawn cultivated to body length and reach 3cm.Then, then respectively from
Sampled in different familys, mixed breeding be put into identical environment after mark until harvest, with to different familys respectively through economic characters
Tested under common environmental cultivating condition, so as to calculate the genetic parameter of each character, family and individual breeding value are carried out pre-
It surveys, and family and individual is selected and remain based on breeding value.However, the common environmental that the independent cultivation of each family for a long time is caused
Effect meeting large effect genetic parameter estimation value and the accuracy of breeding value prediction, so as to influence the accuracy of selection, reduce
Genetic progress is reacted with selection.
The content of the invention
The object of the present invention is to provide a kind of prawn breeding early stage different family common environmental cultivating systems and cultural method,
The cultural method is suitble to cultivation of the prawn difference family early stage under the conditions of common environmental, is tested under the conditions of extension common environmental,
Prawn family common environmental effect is reduced, reduces influence of the environmental variance to genetic variance, beneficial to the extensive family selective breeding of raising
In the process to the accuracy of each genetic parameters estimation, the cultivating system is simple in structure, practical, at low cost, family mark
Note rate and discrimination are 100%.
Technical scheme is as follows：A kind of prawn breeding early stage difference family common environmental cultivating system, including circle
Shape pond, aquaculture net cage and material-feeding platform, are equipped with water inlet pipe and blow-off pipe on circular pond, and aquaculture net cage is equipped with multiple and along circle
Pond pool side is set, and each aquaculture net cage is set there are one material-feeding platform and a nameplate, is equipped with and is filled in aquaculture net cage and circular pond
Gas stone, gas charging stone are connected by inflated hose with air pump, and bolting silk net is equipped in the bottom surface of each aquaculture net cage and side.
Further, a gas charging stone is placed in each aquaculture net cage, is pressed in circular pond per 1-2 inflation of square meter
Stone carries out distribution placement.
Further, the mesh of the bolting silk net is 10-60 mesh.
Further, the water inlet pipe is arranged on circular pond pool side, and the blow-off pipe is arranged on the center in circular pond.
It is a kind of to carry out cultural method of the different familys under common environmental in prawn breeding early stage using above-mentioned cultivating system,
It carries out as follows：
（1）Disinfection：Aquaculture pond, net cage and cultivation apparatus are impregnated with disinfectant, then is rinsed well with clear water, by net cage one by one
It is suspended on circular pond pool wall, is impaled the surrounding of aquaculture net cage and bottom with bolting silk net, the size of mesh is to keep mesh
Subject to the shrimp of permeability and net cage can swim out of；The disinfectant is potassium permanganate or formaldehyde；
（2）Add in filtering sea：Seawater is injected into circular pond, adjusts the physical and chemical indexes such as Inversion phenomenon, the illumination of seawater,
Inflation makes water level in pond be suitble to the dispensing of shrimp seedling；
（3）The shrimp seedling of a length of 0.8 ± 0.2cm of body is put into net cage by identical quantity, each family shrimp seedling is put into one
Net cage, breeding density put 150-300 tail shrimp seedlings in a suitable place to breed for per cubic meter of water；Tracheae, gas stone are put into net cage and circular pond, often
A net cage is put into material-feeding platform 1, for giving prawn bait throwing in when family is cultivated, ingests and grow feelings for observing shrimp body in addition
Condition；
（4）Hang Sign Board：Hanging one at the edge of each net cage has code identification board, and different familys is encoded, with
Distinguish different familys；
（5）Aquaculture management：After each family prawn is put into net cage completion family mark, begin to carry out the day of family cultivation
Often management：The breeding environment and management condition of each family should be consistent；Feed bait 3-4 times daily, day feeding volume is shrimp
The 5 ~ 10% of weight；It according to prawn growing state, regularly replaces bolting silk net or each family aquaculture net cage is changed into cleaning, change new
Net cage continue to cultivate；Good water quality is kept by changing water, periodically launching improver of water quality, seawater pH value is made to be maintained at 7.5-
8.2, ammonia nitrogen≤1mg/l, nitrite≤0.2mg/l, COD COD≤15mg/l, dissolved oxygen DO >=4mg/L, Chi Zhong
Water is kept without heterochromatic, peculiar smell；
（6）Sampling mark：When the young shrimp in each net cage, which continues independent cultivation, reaches 3-4cm to body length, terminate common ring
Border cultivates, and samples be marked from kind family respectively.
The step（5）During aquaculture management, the control of water quality, which can also use to remove, changes water, periodically launches water quality improvement
Method commonly used in the art outside agent controls the pH value of seawater to be maintained at 7.5-8.2, ammonia nitrogen≤1mg/l, and nitrite≤
0.2mg/l, COD COD≤15mg/l, dissolved oxygen DO >=4mg/L keep water in pond without heterochromatic, peculiar smell.
The present invention has the beneficial effect that compared with the prior art：Cultural method of the present invention is suitble to prawn difference family early stage
Cultivation under the conditions of common environmental, extend common environmental under the conditions of test, reduce prawn family common environmental effect, reduce ring
Influence of the border variance to genetic variance, beneficial to the standard estimated during the extensive family selective breeding of raising each genetic parameters
True property, the cultivating system is simple in structure, practical, at low cost, and family mark rate and discrimination are 100%.
