Embodiment Construction
[0030] Using modern biotechnology means, research polyploid induction technology of flounder fish, develop tetraploid fish, and then mate with diploid fish to produce sterile triploid fish population, so as to mass produce sterile fish group.
[0031] Homologous sperm are used to fertilize flounder eggs, and the fertilized eggs are subjected to hydrostatic shock treatment for a certain period of time after fertilization to inhibit the first cleavage and double the chromosomes, which can successfully induce the production of tetraploid fry of flounder, and establish The high-efficiency induction technology for tetraploid fry commonly used in marine flounder and flounder is used for sex control, sterile triploid seed cultivation and sterile seed breeding of these flounder and flounder fish, so as to improve the breeding output and product quality of these fish And economic benefits, has important practical significance and huge potential for promotion and application.
