Abstract
The invention belongs to a fish breeding technology, in particular to a carp family selective breeding method utilizing a net cage. At present, the family selection method is used intensively for the selective breeding of carps, and the traditional method carries out growth performance comparison and selection on multiple families, thus occupying a great quantity of ponds and actually being difficult to practice; and the method of injecting an electronic chip injection family marking mixed cultivation and family selection method has high cost and high requirements on technical personnel and is difficult to popularize. The invention adopts an family selection method utilizing an enclosed net cage to carry out feeding and growth performance comparison on multiple families, eliminates experimental errors caused by pond separated cultivation, saves a great quantity of the water surfaces of ponds, does not need a chip for marking, saves cost, is suitable for common breeding farms and facilitates carrying out selective breeding of multiple families.
Description
Technical field:
This invention belongs to the fish breeding technology, specifically is to utilize net cage to carry out the breeding method of carp family selective breeding.
Background technology:
Carp is China's tradition cultured fishes, also is main cultured freshwater fish, is fit to China overwhelming majority area and cultures.The breed of carp is with a long history, and breed variety is more, and cultural technique is ripe, is difficult to only improve cultured output through cultural technique.So,, need carry out genetic improvement to the kind of current breed in order further to improve the yield and quality of carp.At present, the method that family is selected is extensively adopted in the selection breeding of carp.Family selective breeding is set up a plurality of familys as far as possible under the situation of conditions permit, the family quantity chance of more options more is big more, and the success rate of breeding is just high more, shortens breeding time relatively.Family selective breeding at first will carry out parent population to be chosen and selects, and promptly selects a tail raun and a tail milter with certain genetic background and carries out mating, and the offspring of its breeding promptly is a family.For the growth performance of more different familys, should cultivating condition identical, can distinguish different familys again, used method is at present: one, separately culture in the pond.Be the pond that each family is used the same terms respectively, under identical cultivating condition, culture, support to certain phase and carry out the family growth performance more relatively.Two, family mark mixed breed.Fish length to certain phase (general minimum is about 10 grams) injects its abdominal cavity to electronics stamen sheet, and each chip has specific numbering, reads through corresponding CT scanner.Raise together with the fish of the different familys of numbering sweep record through mark together, support to certain phase and carry out the family growth performance more relatively.First method, generally each family need take a pond, and each pond condition also there are differences, and experimental result is caused error easily.When a plurality of familys are carried out the growth performance comparison, take a large amount of ponds, in fact be difficult to possible; Second method goes for a plurality of familys, but stamen sheet cost is high, and the technical staff is required height, is difficult to popularize.
Summary of the invention
The present invention adopts a kind of closed net cage to carry out the method that a plurality of familys are raised and growth performance compares, and this method has been eliminated and adopted the pond separately to culture the experimental error that is caused, and practices thrift a large amount of ponds water surface.Need not stamen sheet mark, practice thrift cost, be fit to general breeding station and use, can easily carry out the breeding seed selection of a plurality of familys.
The technical scheme that this method technical solution problem is adopted is: a kind of carp family selective breeding method that utilizes net cage, and its characteristic may further comprise the steps:
One, net cage is set.1, the setting of parent population breeding net cage.Can closed net cage, 1 cubic metre of size is placed a fish nest (so that adhering to fish-egg) in grenadine mesh 30 orders, net cage.Net cage is arranged in cement pit or the pond, about 90 centimetres of the depth of waters (attaching ovum in order to increase water body and to make full use of the net cage inwall) in the net cage.2, the setting of fish culture net cage.Can closed net cage, 1 cubic metre of size, grenadine mesh 20 orders, all net cages are arranged in the same pond, and the depth of water is about 70 centimetres in the net cage.Two, set up family.From the carp parent population of identical or different genetic background, by one female one male pairing, mating breeding.Pairing parent population is well put into parent population breeding net cage behind artificial induced spawning, treat to take out parent population after parent population lays eggs.Fish-egg continues to hatch into fry in net cage, in net cage, carry out seed rearing by conventional method then, and two weeks back collection fry changes Chi Zhuanxiang, carries out fry and puts in a suitable place to breed.Three, fry is put in a suitable place to breed.Each family is put two fish culture net cages respectively, and fry is put the quantity unanimity in a suitable place to breed in each net cage of all familys, and net cage is feeding and management under the same conditions.Undertaken selecting for twice by conventional method to 5 centimetres during with 10 centimetres of left and right sides when fry is long respectively, rogue and stay essence, it is identical to remain the interior fry number of each net cage.Four, comparative trial.Measure the growth data of 1 each family every month and note down, culture and after 5 months measurement result is compared analysis.Select the fast family of growth to continue in net cage, to culture, after sexual maturity, carry out the family selective breeding of a new round.Beneficial effect of the present invention: net cage is arranged in the same pond, for each family provides the isometric growth condition, reduces the error that environment caused.Can save pond, man power and material greatly, reduce the seed selection cost, and method be simple, be fit to general breeding units, especially be fit to the seed selection of a plurality of familys.
