福建湄洲岛周围海域浮游动物的分布
Distribution of Zooplankton in waters around Meizhou Island of Fujian
Abstract
根据1990年5月至1991年1月来自湄洲岛海域的浮游动物样品，鉴定出101种终生浮游动物和12类阶段性浮游幼体。桡足类的种类和数量在群落中均占优势。中华哲水蚤、精致真刺水蚤、中华假磷虾、肥胖箭虫和短尾类溞状幼体为主要优势种。海龙箭虫、拟细浅室水母、针刺真浮莹等10种，四季都有分布。本文还描述了总生物量，总个体密度和主要种类的分布，并对夏季浮游动物的分布与上升流的关系，以及总生物量季节变化不明显进行了讨论。 One hundved and two species of holozooplankton and 12 groups of nlerozooplankton, planktonic larvae, were identified in the samples collected in the waters aound the Meizhou island form May 1990 to January 1991, were stutied.Copepoda was dominant in the number of species and total individuals of zooplankton.Calanus sinicus, Euchaeta concinna Pseudeuphausia sinica, Sagitta enflata and Brachyura zoea larvae were main dominant species.10 species, Sagitta nagae, Lensia subtiloides, Euconchoecia aculeata, et al, were distrbutes in 4 seasons.Distribution of the total biomass of zooplankton, the total individuals density of zooplankton and main species were also described.The distribution of summery zooplankton in the studied waters and its relation to upwelling and the nonevident variation of season of the total biomass of zooplankton are discussed.
