The invention relates to an artificial propagation method for takifugu obscurus in winter. The method comprises the following steps of parent fish greenhouse cultivation pool building, parent fish cultivation, parent fish spawning induction, artificial fertilization, fertilized egg hatching and alevin cultivation. According to the artificial propagation method for the takifugu obscurus in winter, the cultivation time of fry from propagation in the current year to overwintering is prolonged, the overwintering cultivation link of the takifugu obscurus is avoided, and the artificial propagation method has the advantages of meeting the market requirement, increasing the cultivation benefit and reducing the cultivation cost.
