Abstract
The invention discloses a cross breeding method for Japanese crucian carp and cyprinus carpio red. As proved by experiments, the combination of the Japanese crucian carp (female) and the cyprinus carpio red (male) which are hybridized has high affinity, and a hybridized generation F1 with superior quality can be obtained. The hybridized generation F1 has the excellent characteristics of infertility, omnivory, high growing speed, large size, good meat quality, good taste, high disease resistance and the like, is capable of overcoming certain biological defects of the Japanese crucian carp and the cyprinus carpio red effectively, and has remarkable hybridizing advantages, and the germplasm is difficult to degenerate.
Description
Technical field
The present invention relates to a kind of Japanese white crucian and make the country prosperous red carp cross breeding method.
Background technology
Crucian and carp are cyprinid fish carp subfamily, are respectively that crucian carp belongs to and carp belongs to, this two belong to fish nutritious, distribute wide, adaptability is strong, easily raise, and is to develop the improved seeds of propagating artificially, is subjected to consumer and culturist's favor deeply.Owing to breed through long-term artificial close relative, the crucian kind has occurred that growth rate slows down, the degeneration sign appears in germplasm, has restricted the raising of culture benefit.In order to overcome these unfavorable factors, people have obtained the good hybrid generation of some proterties by the hybridization means, as Hunan cloud crucian carp, hybridized prussian carp, lotus crucian carp etc.
Japanese white crucian and the red carp of making the country prosperous are ominivore-fish, and the red carp of making the country prosperous is the improved seeds of artificially breeding, and growth is fast, meat is good, premunition is strong, but has been difficult for catching; Though Japanese white crucian is grown soon, is of high nutritive value, easily rises and catch, and is easily ill.
Summary of the invention
Purpose of the present invention just provides a kind of Japanese white crucian and the red carp cross breeding method of making the country prosperous, and that the hybrid that this method obtains has is sterile, feeding habits assorted, the growth fast, individual big, good characteristic such as meat is good, premunition is strong.
Japanese white crucian of the present invention and the red carp cross breeding method of making the country prosperous may further comprise the steps:
1, the selection of parent population: select parent population in autumn, winter, female parent is the breeding Japanese white crucian, and body weight is more than 500 grams, and in 2～3 ages, male parent is the GB red carp of making the country prosperous, and in 1～3 age, body weight is at 1～1.5 kilogram;
2, the cultivation of parent population: put in a suitable place to breed in maternal and male parent branch pond, and maternal 1.5～2 meters of the pond depth of waters of cultivating are put 200～250 kilograms of parent populations in a suitable place to breed for every mu, 20～32 ℃ of water temperatures, dissolved oxygen amount is at every liter more than 5 milligrams, day a feeding volume be 2%～5% of fish body weight;
3, the injection hormone is hastened parturition:
(1) parent population is selected: the parent population of the usefulness of hastening parturition requires maternally to want that belly expands, softness, and the ovary profile is obvious, and the gonoporal process mountain is little red, gently presses belly to have a small amount of ovum grain to flow out, and male parent has the outflow of milky seminal fluid with light pressure belly;
(2) hasten parturition the time: in 4～May, water temperature is more than 18 ℃;
(3) dosage of hastening parturition: 4～5 milligrams of every kilogram of maternal injection carp brain hypophysis (PG) or human chorionic gonadtropin (HCG) 800～1000 international units, or injection 2～3 milligrams+human chorionic gonadtropin of hypophysis (PG) (HCG) 500～600 international units, or luteotropin releasing hormone d-ala analog (LRH-A
2) 3～5 micrograms (new standard), or 1～3 milligram+luteotropin releasing hormone d-ala analog of maleic acid DOM (DOM) (LRH-A
2) 2～3 micrograms (new standard);
To sexually matured female parent, the disposable injection of hormone, to not full ripe female parent, hormone is injected at twice, injects 1/4 or 1/5 of accumulated dose first, injects remaining dosage at interval in 8～10 hours; The male parent dose of medicament is 1/2～1/3 of identical weight female parent, and male parent is disposable injection, and when dividing biphasic injection as female parent, male parent is carried out for the second time simultaneously with maternal inject time inject time;
(4) injecting method: the injection site does not have the squama place, becomes 45 at the pectoral fin base portion
oThe degree subscript is gone into, and 0.3～0.5 centimetre, every this injection volume of tail father and mother is no more than 0.5 milliliter;
4, artificial insemination: prepare clean anhydrous vessel, squeeze ovum on one side, squeeze smartly on one side, per ten thousand ovum are with a seminal fluid, and stir gently with feather, add physiological saline after 1～2 minute slowly, stir gently 1～2 minute again;
5, fertilized egg is carried out the unsticking processing;
6, incubating oosperm: can put into hatching cylinder or circular hatching channal through the fertilized egg of unsticking and carry out the flowing water hatching;
7, the hatching stage finishes: treat that prelarva waist point occurs fully, and normal putting down when swimming, can change spray fry rearing stage or sale over to.
Japanese white crucian of the present invention and the red carp cross breeding method of making the country prosperous, Japanese white crucian is after artificially breeding is cultivated, with the red carp breeding hybridization of making the country prosperous, facts have proved that the affinity of Japanese white crucian (♀) * red carp (♂) hybrid combination of making the country prosperous is stronger, can obtain colory hybrid F
lGood characteristics such as in generation, it has sterile, and feeding habits are assorted, growth is fast, individuality is big, meat is good, delicious, premunition is strong, and can effectively overcome Japanese white crucian and some defectives biologically of the red carp of making the country prosperous, tangible heterosis, hybrid vigor is arranged, and germplasm is difficult for degenerating.
Embodiment
A kind of Japanese white crucian and the red carp cross breeding method of making the country prosperous may further comprise the steps:
1, the selection of parent population: select parent population in autumn, winter, female parent is the breeding Japanese white crucian, and body weight is more than 500 grams, and 2～3 ages are for well, and male parent is the GB red carp of making the country prosperous, and in 1～3 age, body weight is at 1～1.5 kilogram, and this body surface of father and mother is must scale complete, anosis, do not have wound.
2, the cultivation of parent population: put in a suitable place to breed in maternal and male parent branch pond, maternal 1.5～2 meters of the pond depth of waters of cultivating, smooth at the bottom of the pond, no chad, weeds, wild fishes have into, drainage system, put 200～250 kilograms of parent populations in a suitable place to breed for every mu, nurturing period, 20～32 ℃ of water temperatures, dissolved oxygen amount are at every liter more than 5 milligrams, and a day feeding volume is 2%～5% of fish body weight.
3, the injection hormone is hastened parturition:
(1) parent population is selected: after parent population is cultured to gonad maturity, carry out artificial induced spawning, the parent population of the usefulness of hastening parturition requires gonad development good, belly expands the good standard of gonad development, softness for female parent is wanted, the ovary profile is obvious, the gonoporal process mountain is little red, gently presses belly to have a small amount of ovum grain to flow out, and male parent has the milky seminal fluid to flow out with light pressure belly;
(2) hasten parturition the time: in 4～May, water temperature rises to more than 18 ℃;
(3) dosage of hastening parturition: 4～5 milligrams of every kilogram of maternal injection carp brain hypophysis (PG) or human chorionic gonadtropin (HCG) 800～1000 international units, or injection 2～3 milligrams+human chorionic gonadtropin of hypophysis (PG) (HCG) 500～600 international units, or luteotropin releasing hormone d-ala analog (LRH-A
