Method for inducing cyprinus carpio from secondary female to male at high temperature and application

The invention belongs to the field of fish reproductive endocrinology, and discloses a method for inducing cyprinus carpio from secondary sexual female to male by high temperature and application, an applicant treats genetic female juvenile cyprinus carpio subjected to sexual differentiation at high temperature, so that ovaries of the genetic female juvenile cyprinus carpio are degraded and differentiated to testis, and then gonads are mature at normal temperature. The XX pseudo male carp can be obtained by using the method, and a new efficient and environment-friendly parent breeding strategy is provided for all-female carp breeding. 本发明属于鱼类生殖内分泌学的领域，公开了一种利用高温诱导鲤鱼次发性雌转雄的方法及应用，申请人通过高温处理已性分化完成的遗传雌鲤幼鱼，使其卵巢退化并向精巢分化，之后性腺在常温下发育成熟。利用该方法可获得XX伪雄鲤，为全雌鲤育种提供了高效且环境友好的亲本培育新策略。
