The invention discloses a method for artificially inducing parent pseudorasbora parva gonad synchronous development. The method comprises the steps of parent fish selecting, parent fish breeding, parent fish gonad synchronous development and the like. According to the method, through gradual temperature control, gradual lighting adjustment and appropriate feed putting, the purpose of promoting pseudorasbora parva gonad synchronous development is achieved, the problem of sperm and egg malformation caused by rapid environment changes is avoided, the brood rate and the fertility rate are improved and a technical basis is provided for pseudorasbora parva artificial breeding.
