The scyphistomae of Rhopilema esculenta were cultivated under different nul,ritional conditions in Laboratory. Seven groups were divided, and fed with freshly hatched naupill of Artemia sp.Feeding intervals were 1, 2, 4, 7,14, 21 and 28 days for each group respectively. The effect of nutrition on the formation and germination of the poaocyst were observed. The scyphistomae produe e 7 .4 po-docysts on the average under feeding each day, and germinating rate can reach 28.6%.In lack of nutriment, the formation of podacyst is inhibited or very few.The scyphistomae would produce only 1.1 podocysts on the average under malnutri-tion, and germinating rate is scarce or unable to germinate. It indicates that the number of podoeyst formed and germinating rate are closely related to nutrient level of scyplaistomae.
