Abstract
The invention discloses a large-scale artificial induction gynogenesis flowerThe method comprises the following steps: first, selecting sexual mature male fancy carp and female flowerArtificial oxytocic is carried out, and then the fancy carp sperms and flowers which are subjected to ultraviolet inactivation are treatedMixing ovum, stirring with feather to activate ovum, subjecting the activated ovum to cold shock treatment in yellow mud of 0-1 deg.C for 20-22min, sequentially subjecting to water of 4-6 deg.C, 8-10 deg.C and 15-18 deg.C for 1-2min, and subjecting to water temperature of 22-2 deg.CHatching in a hatching tank at 5 ℃, and obtaining the gynogenesis flower of the diploid after identification and screeningThe cultivation method of the invention can reduce the damage of the rapid temperature rise to the fertilized eggs, improve the hatchability of the fertilized eggs and the survival rate of offspring, and effectively overcome the defect that the viable female nucleus developed flowers are difficult to obtain by the conventional methodSuccessful achievement of gynogenesis flowersGroup, fill up the flowerBlank in gynogenesis technology.
Description
Technical Field
Background
Gynogenesis is an important genetic breeding method and an effective way for quickly establishing a pure line, and the gynogenesis of 1-2 generations is equivalent to the continuous breeding of 8-10 generations of traditional inbreeding. Through gene purification, individuals carrying harmful genes are naturally eliminated in the gynogenesis process, so that gynogenesis offspring often show excellent characters of hypoxia resistance, strong stress resistance, fast growth speed and the like.

The method effectively overcomes the defect that the conventional method is difficult to obtain the viable female hairFlower growingSuccessful achievement of gynogenesis flowersGroup, fill up the flowerBlank in gynogenesis technology. Gynogenesis also has a "heterospermic effect". Inducing flower by using genetically inactivated heterogenous koi spermIn fish, there may be DNA hybridization during induction. By microsatellite map experiments, we confirm that gynogenesis flowersThe genome contains a segment of koi. DNA fragment and flower of koi spermThe DNA fragments of the genome are hybridized, and the biological characters, such as growth, stress resistance, body color and the like, can be influenced to a certain extent.
In order to solve the technical problems, the technical scheme provided by the invention is as follows:
artificial large-scale induction gynogenesis flowerThe method comprises the following steps: first, selecting sexual mature male fancy carp and female flowerArtificial oxytocic is carried out, and then the fancy carp sperms and flowers which are subjected to ultraviolet inactivation are treatedMixing ovum with featherStirring to activate ovum, placing the activated ovum in yellow mud of 0-1 deg.C for cold shock treatment for 20-22min, sequentially placing in water of 4-6 deg.C, 8-10 deg.C, 15-18 deg.C for 1-2min, placing in hatching tank with water temperature of 22-25 deg.C for hatching, and identifying and screening to obtain gynogenesis flower of diploid。
During the hatching process of the fish fertilized eggs, the temperature changes sharply to cause the fish fertilized eggs to die in large quantity. In previous experiments, the activated ovum after cold shock treatment is directly transferred into water with the water temperature of 22-24 ℃, and a large amount of female nucleus growing flowers are not obtained without gradient heating treatmentAfter cold shock treatment, the activated eggs are subjected to gradient temperature rise, so that the hatching rate and the survival rate of fertilized eggs can be obviously improved. Meanwhile, the invention discovers flowersThe ovum has certain viscosity, and cold shock in yellow mud can remove viscosity between ovum and ovum, thereby enlarging the development of gynogenesisNumber of eggs, followed by running water hatching, to increase yield.
Preferably, the artificial induced spawning method specifically comprises the following steps: by injecting the female flowers onceInjecting, wherein the injection dosage is 400-500IU/Kg per tail according to chorionic gonadotropin, 6-8ug/Kg of lutein release hormone analogue and 1mg/Kg of diutanone; simultaneously injecting 3-4 male flowersFish preparationThe amount is half female dose; the injection dosage of male Cyprinus Carpio is 800-1000IU/Kg per tail according to chorionic gonadotropin, and the luteinizing hormone releasing hormone analogue is 6-8 ug/Kg.

APreferably selecting individuals with more than 2 years old, good development without disease state and obvious sexual maturity characteristics, and selecting individuals with more than two years old, good development without disease state and obvious sexual maturity characteristics from the fancy carp; flower (A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. AAnd putting the carp into a parent fish pond for artificial intensive culture for 3-4 months before artificial spawning induction.
Preferably, after the injection of the artificial induced spawning is finished, the male and female flowers are separatedPlacing in the same spawning pond, every 10 female flowersPutting 2 male flowers(ii) a And (3) placing the male fancy carp into another spawning pond, fishing the male fancy carp after the artificial oxytocic injection is performed for 6-10h, diluting the male fancy carp by using Hank's solution after the sperm is extruded, performing ultraviolet inactivation, and performing artificial dry insemination.
Preferably, the flowerInjecting fresh running water into the parent fish pond to make flower alignment 20-30 days before induction of laborAnd (5) ripening is performed.
Preferably, the temperature of the pond water is maintained at 22-25 ℃ when artificial spawning is performed.
Preferably, the ultraviolet inactivated koi sperm is obtained by the following method: slightly pressing the abdomen of the male koi to extrude the sperms from the cloaca, quickly diluting the sperms by using Hank's liquid precooled at 4 ℃ according to the volume ratio of 1:2-3 after the sperms are taken by a dry and clean container, then spreading the diluted sperms in a thin layer form in a culture dish precooled at 0-4 ℃, placing the culture dish on a shaking table padded with an ice plate, and irradiating the culture dish by using an ultraviolet lamp until the ultraviolet inactivated koi sperms with the inactivation degree of 70-80% are obtained.
More preferably, the specific operation of the ultraviolet lamp irradiation comprises the following steps: irradiating 2 ultraviolet lamps (15W) which can emit obvious ozone smell at a position 10-12cm away from sperms, dipping semen every 1-2min after irradiating for 15min, coating the semen on a glass slide, activating with water, performing microscopic examination to judge the activity of the semen, and stopping irradiation when 70-80% of sperms have obviously weakened motility to obtain ultraviolet inactivated koi sperms. During gynogenesis, the degree of sperm inactivation is closely related to the power of gynogenesis. Incomplete inactivation will produce hybrid progeny, and excessive inactivation will result in the inability of the sperm to activate the ovum to initiate development. Because sperm from different individual sources may be viable differently, the inactivation time is different. The invention adopts about 70 percent of sperm motility obviously weakened as a standard, and can improve the success rate of gynogenesis.
Preferably, the activation time of the ovum is 1-2 min.
