Abstract
The invention relates to a high-intensity selecting and remaining method of good carp parents. At present, in a selective breeding process of carps, the selection of standby parent fishes can be carried out only once within a breeding cycle, and the selection intensity is about 10 percent, i.e. 1/10 parents are reserved as standby parent fishes. Generally, a breeding cycle of the carps needs 2-3 years, and the selective breeding of a good breed needs to go through a plurality of breeding cycles, thus the prior breeding method for selecting and remaining the parents needs a relatively longer time to achieve a good breed. In order to overcome the defects that the selection can be carried out only once, the selection proportion is higher and the breeding pertinence is weaker in the selectingand maintaining process of the carp parents at present, the selection is carried out for multiple times aiming at main economic traits according to different growth and development stages of the samegeneration of fishes from fish fries to ripe fishes for laying eggs, and the selection intensity is improved, and the selections of a generation are equal to the selections of multiple generations, thus the time for selective breeding is greatly shortened, and the selection effect is improved.
Description
Technical field:
This invention belongs to the fish breeding technology, is specifically related to carp parent's the method for selecting and remain.
Background technology:
At present, in the selection breeding process of carp, select reserve parent fish, in a breeding cycle, only once select.Selection intensity is about 10%, promptly keeps parent's individuality of 1/10th and gives over to reserve parent fish.The breeding cycle of carp generally needs 2-3, and the seed selection of improved seeds need be experienced a plurality of breeding cycles.This parent's that selects and remain breeding mode, the time limit that reach the improved seeds target is longer relatively, will select simultaneously a plurality of targets toward contact as required, causes selecting effect also not obvious.
Summary of the invention:
In the carp seed selection process, the fish individuality of selecting and remain is few more, and the individuality of eliminating is just many more, and the mean value of the selected proterties of the fish of selecting and remain is big more apart from the difference of the mean value of whole colony, and promptly selection differential is big more, and selection effect is big more.Carp has bigger fertility, is favourable to improving selection intensity.And select number of times many more, select effect obvious more.
Select and remain in the process in order to overcome present carp parent, a breeding cycle is only selected once, the ratio of selecting is higher, the breeding specific aim is more weak problem relatively, and the different growth and development stages that the present invention was laid eggs from the fry to the maturation according to the same generation are repeatedly selected at main economic characters, and raising selection intensity, a generation has equaled to finish the selection of a plurality of generations, has so just shortened the time limit of seed selection kind greatly, has improved the selection effect.
The technical solution adopted for the present invention to solve the technical problems: a kind of good carp parent's the high strength method of selecting and remain, its feature may further comprise the steps:
One, the pairing breeding of hastening parturition: by the end of April at the beginning of 5 months, when carp parent fish live through the winter pond water temperature rises to 18 ℃ of left and right sides, inspection parent population mature condition.Press belly with hand push, when gonopore flows out, show the parent population maturation, carry out the artificial induced spawning injection this moment as seminal fluid or ovum grain.Select the parent population of about 1 kilogram of body weight, female, pairing in male 1: 1, the parent population pairing should be more than 100 groups.
