摘要： The invention discloses a method for controlling fish reproduction, the method comprises the following steps of: A, constructing a recombinant gene CMV-eGFP-SV40-CMV-Ga14-SV40 and establishing a GAL4 transgenic zebrafish line; B, constructing a recombinant gene CMV-RFP-SV40-UAS-antisense dnd and establishing a uas-antisensednd transgenic zebrafish line; and C, hybridizing by taking homozygous transgenic fish of the two lines as parents, and the hybrid generation fish was sterility. The method of the present invention takes a strategy that two fertilizable lines hybridized but hybrid generation is sterility, establishing a novel method with a universal meaning for controlling fish fertility; The method solves the contradiction of the reproductively sterility of fish and the hereditability of characters in a reproduction operation research and can be effectively applied to cultivation of new fish specie and population control.
