The present disclosure provides a combination of antisense RNA sequences and use thereof in the production of tilapia with degenerated sexual organs, belonging to the technical field of molecular biology and reproductive biology, the combination of antisense RNA sequences includes antisense RNA of steroidogenic factors SF1-1 and SF1-2; the nucleotide sequences of Anti-SF1-1-I, Anti-SF1-1-II, Anti-SF1-2-I and Anti-SF1-2-II are set forth in SEQ ID NO:1-SEQ ID NO:4 respectively. The method of the present disclosure introduces antisense RNA fragments into the eggs through the fertilization hole to realize effective and accurate targeted intervention for regulating the gene expression, and the method has the advantages of simple operation, minimal egg damage, high success rate, stable phenotype after breeding, and excellent application prospects.
