福清湾及附近海域浮游动物的数量和分布

本文分析了2005年10月和2006年5月在福清湾及其附近海域采集的浮游动物样品,结果表明,福清湾已鉴定的浮游动物有64种,10类浮游幼体.分为4个生态类群,包括河口低盐类群,近岸暖温类群,近岸暖水类群和广布外海类群.浮游动物物种多样性指数春季高于秋季.春季浮游动物总个体数均值为(161ind/m3)高于秋季的(83ind/m3),春季生物量均值为(67.7mg/m3)低于秋季的(87.7mg/m3);浮游动物总个体数的平面分布,春季湾内西部水域最高,海坛海峡最少;秋季福清湾东部水域最高,湾内西部水域最少.浮游动物生物量和总个体数的平面分布趋势基本一致.另外还对浮游动物的分布与环境因子的关系进行了分析.

Abundance and distribution of zooplankton in Fuqing Bay and its neighboring waters

Based on samples collected from the survey 2006, the analysis show that there are 64 species and in Fuqing Bay during the period of October 2005 and May 10 groups of pelagic larvae in the surveyed areas. The zooplankton can be divided into 4 ecotypes, i.e. estuary low salinity gronpes, coastal warm-temperate, coastal warm water and wide-spreading oceanic. The species diversity of zooplankton is higher in spring than that in autumn. The abundance of zooplankton is higher in spring than that in autumn, and the biomass in spring is less than that in autumn. In spring the highest abundance of zooplankton was located in the west part of Fuqing Bay while the lowest that in Haitan strait. In autumn the highest abundance of zooplankton was located in east part of Fuqing Bay while the lowest one in the west. The horizontal distribution patterns were similar for the biomass and the abundance of zooplankton. The distribution of zooplankton and its relations with environmental factors were also analyzed.
