摘要	Strobilation of the giant jellyfish, Nemopilema nomurai, has been found to occur in late spring to early summer near Chinese estuaries, suggesting that seasonal warming and hyposalinity may be the crucial influencing factors. This study examined their combined effects by exposing post-overwintered N. nomurai polyps (cultured at 5 degrees C for 2.5 months) to four temperatures (10, 13, 16 and 19 degrees C) and seven salinities (11, 15, 18, 20, 23, 28, and 33) in approximate ambient strobilation period. Strobilation of N. nomurai occurred in all treatments. However, exposure to 10-16 degrees C and salinity 15-23 resulted in polyps with significantly enhanced ephyra production via a remarkable increase of average strobilation frequency and prolongation of the strobilation stage; additionally, the mortality of post-strobilated polyps and the decreased percentage of calyx diameter were notably low compared to the other groups. These results indicate that seasonal warming was a trigger for N. nomurai strobilation. Medusae were more likely to bloom if the duration at relatively cool temperatures (10-16 degrees C) was prolonged in spring. During the strobilation, the polyp population in situ would decline after releasing massive number of ephyrae. However, exposure to hyposalinity could relieve this case and ensure sustainable development of post-strobilated polyp population better, which was a momentous advantage of estuaries as the habitats for N. nomurai over other regions.
