Due to the adoption of the method, male fugu rubripes fries can be produced rapidly, the male rate in the fries is 65-80 percent, the average male rate is 75 percent, ultraviolet ray irradiation is not required, sex hormone is not fed, and complex operation processes are avoided; and the method is low in cost, is easy to operate, and has contribution to mass production.
