中文摘要：
根据2005～2007年6月上旬和7月上旬在辽东湾海蜇放流区进行的大型水母调查及同期进行的浮游生物调查数据,分析了该区域大型水母及浮游动物的数量分布特点以及海区中浮游动物的生态类型和优势种,并且试图寻找浮游动物的数量分布与大型水母的数量分布的关系。结果表明,浮游动物的优势种为小型桡足类及桡足类幼体：双刺纺锤水蚤Acartia bifilosa、小拟哲水蚤Pa-racalanus parvus、强额拟哲水蚤Paracalanus crassirostris、桡足类幼体、无节幼体。大型水母主要有：海蜇Rhopilema esculentum、沙蜇Nemopilema nomurai、白色霞水母Cyanea nozakii。大型水母的高密集区往往位于浮游动物高丰度区的附近。
英文摘要：
Distribution of giant jellyfish and major zooplankton,the ecological type and dominant species of zooplankton,were analyzed based on the sampling data obtained during the surveys in jellyfish release area of Liaodong Bay,the Bohai Sea,in June and July,2005～2007. The relationship between zooplankton and giant jellyfish abundance distribution was explored. The results showed that there were three major giant jellyfish,Rhopilema esculentum,Nemopilema nomurai and Cyanea nozakii and three major zooplankton,Acartia bifilosa,Paracalanus parvus and Paracalanus crassirostris in the survey area. Besides,Copepodid and nauplii were other two important zooplankton components. The distribution sites with high catch density of giant jellyfish were usually close to the distribution sites with highly abundant zooplankton.
