饵料浮游动物是海洋经济水产动物直接或者间接的饵料,对它的研究有着重要的理论意义和实用价值.根据2007年2、5、8、11月福建省三沙湾4个航次的调查资料,分析三沙湾饵料浮游动物的生态特征.共鉴定饵料浮游动物82种(类);饵料浮游动物生物量均值为94.52 mg/m~3,占浮游动物总生物量的90.21%,生物量季节分布呈典型双峰型:春、秋两季高于夏、冬两季,且随着季节的变化,呈现不同的平面分布特点;丰度的季节变化和平面分布特点与生物量的季节变化趋势一致;分析结果显示,水温和不同流系是影响三沙湾饵料浮游动物季节变化与平面分布的主要因素.三沙湾饵料浮游动物群落多样性丰富,均匀度均较高,表现出较高的稳定性;小拟哲水蚤(Paracalanus parvus)是三沙湾的主要优势种类.

Based on 4 cruises seasonal data of investigation on February,May,August and November,2007 in Sansha Bay,Fujian Province,the research focused on the ecological characteristics of the food zooplankton.82 species of food zooplankton were identified.The mean value of biomass was 94.52 mg/m~3,which accounted for 90.21% of total zooplankton biomass.The biomass in spring and autumn were greater than in summer and winter,and its distribution showed different features with seasonal variation.The features of seasonal variation and distribution of abundance for food zooplankton were similar to biomass.The high diversity index and uniformity index showed the stability of food zooplankton community.Paracalanus parvus was the dominant species in Sansha Bay in each season.
