Description
Technical field
The present invention relates to a kind of producing method for seed being sheerly yellow large squama Barb.
Background technology
Large squama Barb (Barbuscapito), belongs to Cyprinidae, Barbinae, Barb belongs to, and the river being mainly distributed in the Caspian Sea of West Asia and the Saltwater Sea and flowing through is local famous and precious large-scale economic fish.This fish length can reach 70cm, body weight 12kg, and merits such as having that Salt And Alkali Tolerance is high, feeding habits are wide, delicious meat, growth are fast, does not still carry out artificial breeding research abroad, still locate the wild reset condition under natural water area.2003 under the support of the Ministry of Agriculture " 948 " project; domesticly introduce wild large squama Barb from Uzbekistan first; through research and the test of Heilungkiang aquatic products research institute scientific research personnel more than ten years; whole artificial propagation and the large-scale production of this fish is achieved first in China; and carried out cultivating promoting in multiple provinces and cities, create good economy, society and ecological benefits.The large squama Barb body colour of fishing for acquisition at wild environment is all silver-gray individuality mostly, does not still report yellow individual appearance.This is because under natural water area environment, large squama Barb breeds parental population comparatively greatly, and genetic diversity is higher, and the possibility of the filial generation inbreeding of generation is less, even if there is the individuality of recessive body colour to occur, also can ingest by natural selection or by other feral animals.
Summary of the invention
The invention provides a kind of producing method for seed being sheerly yellow large squama Barb, providing operation basis for obtaining the yellow large squama Barb of pure lines.
A kind of producing method for seed being sheerly yellow large squama Barb of the present invention, it carries out according to following steps:
One, adopt from natural water area and catch the large squama Barb of wild silver gray, cultivate to gonad maturity;
Two, female, the male wild large squama Barb of previous step gonad maturity is carried out artificial induced spawning, insemination and hatching, obtain F1 silver gray individual; The F1 silver gray individuality obtained is carried out next-step operation;
Three, the silver gray F1 individual feeding upper step obtained, in pond, is cultivated to gonad maturity;
Four, take the filial generation inbreeding of same Parent, female for the F1 of previous step gonad maturity, milter are carried out artificial induced spawning, insemination and hatching, bred by silver gray F1 selfing and obtain F2;
Five, F2 reaches after 2 ~ 3cm through pond rearing, and it is individual that separation screening obtains yellow large squama Barb;
The large squama Barb individuality of the yellow six, obtained by previous step separation screening retains, then cultivates to gonad maturity;
Seven, cultivate to sexually matured yellow large squama Barb individuality in previous step, female, the male parent population of Stochastic choice carries out artificial induced spawning, insemination and hatching;
Eight, the filial generation obtained by previous step is all that yellow large squama Barb is individual, namely completes the production of hybrid seeds process of the yellow large squama Barb of described pure lines.
The present invention comprises following beneficial effect:
The present invention catches the large squama Barb of 1 wild silver gray in age breed by adopting natural water area, finally cultivates the fingerling completely with the yellow large squama Barb of pure lines.
Large quantity research shows, cinerous and the Red color trait of most fish are controlled by 2 pairs of genes, cinerous is dominant, red is recessive, genotype is that RRBB, RrBB, rrBB, RRBb, RRbb, RrBb, rrBb and Rrbb show dominant steel gray body colour, only has genotype to be that rrbb just can show redness.Therefore, occur that the large squama Barb probability of recessive body colour is less at occurring in nature, even if there is the individuality of other body colour recessive to occur, also can ingest by natural selection or by other feral animals.
A kind of producing method for seed being sheerly yellow large squama Barb that the present invention adopts, first the father and mother parent with recessive gene r and b is obtained by the mating of wild large squama Barb, but because the genotype showing steel gray body colour is more, therefore, yellow can't be there is in most of silver gray F1 self-bred progeny, only have Parent to control two pairs of genes of body colour simultaneously all with recessive gene, if genotype is RrBb, rrBb and Rrbb mating, just may there is yellow in filial generation.According to Mendelian independent assortment genetic development, RrBb × RrBb mating, there will be the genotype rrbb yellow of 1/16; RrBb × rrBb or Rrbb mating, there will be the genotype rrbb yellow of 1/8; RrBb × Rrbb mating, there will be the genotype rrbb yellow of 1/4.Due to the homozygote that yellow is recessive genotype rrbb, therefore, the filial generation of yellow F2 selfing is all yellow, namely obtains a kind of producing method for seed being sheerly yellow large squama Barb.
