A method for controlling the process of hatching of Trionychidae zygotes is disclosed. The method comprises keeping the Trionychidae zygotes in 14-20 ℃ for 5-35 days, then shifting the Trionychidae zygotes in 22-34℃ for hatching the Trionychidae zygotes. The Trionychidae zygotes are the 5th-13th days after being laid. A hatching accumulated temperature is between 37500 and 49108 hours-℃. Humidity is kept as 70-100% during the whole method. Accordingly, the hatching time can be delayed.一種甲魚受精卵孵化控制方法,係用以延緩甲魚受精卵孵化時間,其包含:將甲魚受精卵置於14~20℃之低溫環境,保存5~35天;及續將該甲魚受精卵置於22~34℃之孵化溫度進行孵化;其中,該甲魚受精卵係為產出第5~13天之甲魚受精卵,該甲魚受精卵之孵化積溫值係介於37500~49108小時.℃之間,且該甲魚受精卵孵化控制方法中,全程溼度均為70~100%。
