The present invention belongs to the field of aquatic biological breeding, and specifically relates to a method and application of creating germplasm without intermuscular spines of economic fish for breeding. runx2b The economic fish, Megalobrama amblycephala, is gene-edited using a gene as the target gene. F0 generation fish with mutations are selected and cultured as parent fish. The F1 generation is produced by mating and breeding the F0 generation mutant male and female parents. F1 fish without intermuscular spines are screened and cultured to adult fish for use in cultivating a new germplasm of Megalobrama amblycephala without intermuscular spines. The present invention utilizes a gene mutation method to obtain a new germplasm of the economically cultivated fish, Megalobrama amblycephala, without intermuscular spines. This provides an improved method for solving the problem of the significant impact of intermuscular spines in the muscles of important aquacultured economic fish such as silver carp, bighead carp, carp, crucian carp, and bream in my country on their consumption and processing. It also provides a basis for subsequent research on the molecular formation mechanism of intermuscular spines, and has important scientific research value and industrial application value.
