| 摘 要： | 白色霞水母是我国沿海主要致灾水母种类之一,利用野外调查和控制实验相结合的方法,研究了盐度对白色霞水母螅状体存活、生长和横裂生殖的影响以及盐度对白色霞水母碟状幼体存活和生长的影响。结果表明,白色霞水母螅状体生存的盐度上限为35,下限为12.5,生长最适盐度范围为15—32.5。盐度30和32.5组螅状体横裂率最高,与其它各盐度组的螅状体横裂率差异极显著(P<0.01)。白色霞水母碟状幼体生存的盐度上限为35,下限为15,生长最适盐度范围为20—35。

| Abstract: | In field investigation and laboratory experiments on Cyanea nozakii Kishinouye,We investigated the effect of salinity on survival,growth and strobilation of scyphistomae,as well as survival and growth of ephyrae.The results indicated that the upper and lower critical salinity for the survival of scyphistomae were 35 and 12.5,respectively.The optimum salinity for growth was in the range of 15—32.5.The strobilation rates were highest in salinity 30 and 32.5 groups,which were significantly different from other groups.The upper and lower critical salinity for the survival of ephyrae were 35 and 15,respectively.The optimum salinity for growth was in the range of 20—35. |
