摘要
海月水母是一种广泛分布的世界性近岸种,也是我国近海海域大型水母优势种之一.近年来海月水母在世界各地频繁暴发,对海洋生态系统和沿岸经济、社会发展带来了很大危害.海月水母有复杂的生活史(营附着生活的螅状体世代和营浮游生活的水母体世代)和多种无性生殖(出芽生殖、横裂生殖、足囊生殖等)及有性生殖方式.环境因子影响海月水母生活史的各个阶段,如浮浪幼虫阶段、螅状体阶段、碟状体阶段等.这些生长阶段尤其是早期生长阶段的状态(如附着、分布、扩散等)会进一步影响海月水母的种群动态.本文以海月水母生活史为主线,系统总结分析了国内外关于环境因子对其生活史各阶段的影响,提出了一些值得进一步深入研究的问题,以期为我国近海海域水母暴发关键因子的研究提供借鉴.
Aurelia spp. is a cosmopolitan coastal species, and also, one dominant species of large jellyfish in the coastal waters of China. In recent years, Aurelia spp. bloom events occur frequently in the world, causing severe damage to marine ecosystems, coastal economy, and society develop- ment. Aurelia spp. has a complicated life history comprising a benthic asexually-reproducing polyp generation and a sexually-reproducing medusa generation, and various vegetative reproduction （budding, strobilation, and podocyst production） and sexual reproduction. Surrounding physical and biological factors affect each growth stage of Aurelia spp., especially the juvenile stage of planktonic-benthic life cycle, which has major effect on the population dynamics of Aurelia spp. This paper reviewed the research advances in the effects of environmental factors on Aurelia spp. at its different growth and development stages, and discussed some problems worthy of further study, aimed to provide useful reference for the research of the key factors controlling the jellyfish blooms in coastal waters of China.
