Takifugu obscurus south-north relay breeding method

The invention relates to a Takifugu obscurus south-north relay culture method, which comprises the following steps: breeding Takifugu obscurus fry in advance in Jiangsu province from November to December in the last year, then performing fry thickening by utilizing the advantage that the water temperature is higher than that of the Jiangsu province from December in the last year to April in the current year in Guangdong province, and finally transporting the fry back to the Jiangsu province in April in the current year for commercial fish culture. According to the method, the breeding period of the takifugu obscurus is greatly shortened, the takifugu obscurus can be bred into the market specification of 300 g per takifugu obscurus on average in the current year, the technical problem that cross-year breeding is needed in the current takifugu obscurus commercial fish breeding process is solved, death and weight loss in the cross-year overwintering process are avoided, and the yield of the takifugu obscurus is
