摘要
根据2010—2011年在山东南部各海湾进行海蜇放流后的资源分布调查及同期进行的浮游动物调查数据,分析该海域海蜇总数和浮游动物数量分布特点及海区中浮游动物的生态类型和优势种,探讨浮游动物优势种分布和放流海蜇的数量分布关系。经过调查发现,2010年浮游动物的优势种为桡足幼体、无节幼虫、中华哲水蚤、疣足幼虫、真哲水蚤、根状拟铃虫等;2011年浮游动物的优势种为夜光虫、桡足幼体、无节幼虫、长腹剑水蚤、巴拿马网纹虫、真哲水蚤;调查结果显示:调查年份海蜇与浮游动物的分布未呈现相关性。但两年调查中海蜇与桡足类分布均存在负相关性,即海蜇分布与桡足类存在一个此消彼长的关系。
The total number of jellyfish and distribution of zooplankton quantity including zooplankton ecological type and dominant species were evaluated in coastal southern Shandong after jellyfishwas released from 2010 to 2011 based on the resources distribution surveys and contemporaneous zooplanktonic survey data to explore the quantitative distribution of zooplankton dominant species and jellyfish released. It was found that in 2010 the predominant zooplankton species were copepod nauplii, Calanus sinicus, and wart foot larvae, Eucalaninus, Tintinnopsis. In 2011 zooplankton, Noctiluca scintillans, copepod larvae, nauplii, Favella panamensis Kofoid ＆ Campbell, and Eucalaninus were the predominant species. The survey showed that there was significantly correlation between jellyfish profile and the zooplankton profile. However, the two years survey indicated that there was a negative relationship between jellyfish profile and copepod profile, a shift in the relationship between jellyfish distribution and copepods.
