Male/female sex regulation method of Macrobrachium rosenbergii

The invention provides a method for regulating Macrobrachium rosenbergii male/female sex. The method is implemented by lowering or silencing the expression level of the sex protein with the sequence disclosed as SEQ ID NO:1 in the Macrobrachium rosenbergii or derived proteins thereof before the period between the embryonic development stage and post larva stage of postembryonic development of the Macrobrachium rosenbergii. The method solves the technical problems in the shrimp all-male offspring culture in the aquiculture field at present. An RNA (ribonucleic acid) interference technique and a gene expression regulation technique are adopted to perform oriented sex control and induce the shrimp sex reversion, thereby establishing a verification technique system and platform for shrimp sex control and unisexual culture, and a sex-controllable female parent is utilized to culture the all-male unisexual offsprings. 本发明提供种调控罗氏沼虾雌雄性别的方法，是在罗氏沼虾胚胎发育期至胚后发育的后期幼体期之前，降低或沉默罗氏沼虾体内序列为SEQ？ID？NO:1的性别蛋白或其衍生蛋白的表达量来完成的。本发明方法攻克目
