环境因子对海蜇早期幼体发育影响的生态学研究进展

Effect of different environmental factors on early development of jellyfish,Rhopilema esculenta

海蜇是经济价值很高的大型食用水母,历来是我国沿岸渔业的重要捕捞对象。本文综述了营养条件、温度、盐度、光照、溶氧、重金属、pH、氨氮对海蜇足囊繁殖与横裂生殖以及螅状体与碟状体生存的影响,对海蜇早期幼体发育的研究进展情况进行了概述。总结发现:环境因子对海蜇幼体发育影响的作用机理有待进一步探讨,环境突变对海蜇横裂生殖的影响以及海蜇碟状体到水母体系统发育过程的研究尚需补充完善。

Rhopilema esculenta is an important edible medusa in Chinese coastal fishery. This paper focuses on the effect of different environmental factors on early development stages of Rhopilema esculenta. The influences of nutrition, temperature, salinity, light, DO, heavy metal, pH and ammonia on scyphistoma and ephyra are reviewed. In conclusion, the effect mechanism of environmental factors on early development of jellyfish remains to be explored and the studies on the development process from ephyra to medusa is in need of being completed and perfected in the future.
