Abstract Strobilation is a key stage for polyp-to-jellyfish transition. Knowledge about the strobilation induced factors and the effect of temperature on the time and number of strobilation can help improve jellyfish Rhopilema esculentum artificial breeding, as well as optimize the jellyfish seedling method. The time and number of strobilation in polyps were investigated at 25 ℃ raising by 1 ℃ daily (T1) and 2 ℃ daily (T2) and 1 ℃ weekly for 100 days. The results showed that in the T1 group with increasing 2 ℃ ephyrae were started to release on the 8th day, and the water temperature during the peak period of releasing ephyrae was 21 ℃, and the cumulative number of ephyrae was 771 on average. In the T2 group with increasing 1 ℃ ephyrae were started to release on the 13th day, and reach their quantitative peak on the 17th day, when the temperature reaches about 19—21 ℃, and the cumulative number of ephyrae was 1117 on average. There was only one strobilation process in the two groups. In the T3 temperature group, the temperature slowly increased by 1 ℃ every week when the temperature was below 5—10 ℃, and the temperature increased 1 ℃ every 4 days when the temperature was in 10—15 ℃, and then the temperature increased 2 ℃ every two weeks, and keep the water temperature at 19 ℃ for all the temperature time. The result showed that the first time for releasing ephyrae was the 53rd day, and the water temperature during the peak period was 14—15 ℃, and the cumulative number of ephyrae was 1433. In the second strobilation period, the started time for releasing ephyrae was the 74th day, and the water temperature during the peak period was 17 ℃, and the cumulative number of ephyrae was 1010. In the third strobilation period, the started time for releasing ephyrae was the 88th day. The water temperature during the peak period was 19 ℃, and the cumulative number of ephyrae was 496. The cumulative number of ephyrae in the T3 group was 2939. These findings suggest that different temperature changes significantly affect strobilation process and the number of releasing ephyrae. The temperature control in spring can not only obtain jellyfish seedlings in controlled time, but can also increase the yield of jellyfish seedlings.
