Embodiment Construction

[0020] The manner of implementing the present invention can be carried out with reference to FIG. 2 . Its specific technological process is as follows:

[0021] (1) Artificial induction of labor can be carried out as usual, that is, select female fish with uninjured body surface, swollen and soft abdomen, and well-developed gonads and sexually mature male fish to artificially induce labor with chorionic gonadotropin and ovulation-stimulating hormone for fish. One-time injection at the base of the pectoral fin of each fish, the dose of oxytocic agent: 800 IU of human chorionic gonadotropin for female fish, 10 μg of ovulation hormone No. 2 for fish. The dosage for male fish was halved. That is, 400IU, 5μg chorionic gonadotropin and fish ovulation hormone No. 2 are products jointly produced by Hangzhou Animal Pharmaceutical Factory and Xiaoshan No. 1 Veterinary Drug Manufacturing Co., Ltd. Put it in a water temperature of 26°C. After 24 hours, extrude the semen from the male fi...

Abstract

The invention relates to a method for producing male fish, wherein it comprises that: artificially inducing; artificially inducing the female and male fishes; artificial insemination; inverting hormone; feeding seed with Artemia which contains hormone; converting male into biological female; the female grows. The invention comprises sperm inactivation and female diploid generation, to generate ready male fish and normal female fish; crosses the male fish and female fish to obtain the full male fish; inverts the male fish into biological female fish to cross with male fish, to obtain the full super male fish.

Description

technical field [0001] The method of sex reversal and gynogenesis for continuous production of all male yellow catfish belongs to the field of fish cell engineering breeding, and particularly involves artificial sex control technology. Background technique [0002] As proposed in the attached reference materials [15] submitted in the request for substantive examination of this application document: there are several methods to choose from for the production of unisexual male fish: such as artificial selection, direct androgen-induced sex reversal, androgenesis, androgenic Interbreeding, artificially induced triploids, and genetic methods. However, due to the high labor intensity of manual selection and the inability to accurately distinguish between male and female fish; direct induction of sex reversal with sex hormones has the risk of residual sex hormones, and many countries have already banned them. Androgenic development has serious technical obstacles such as low indu...
