| 摘 要： | 为探讨凡纳滨对虾养殖水体中浮游生物群落的演替,对虾池水体中浮游生物群落组成和其多样性进行了分析.研究结果表明:在凡纳滨对虾养殖水体中,浮游植物的优势种主要由小球藻(Chlorella sp.)、波吉卵囊藻(Oocystis borgei)、小环藻(Cyclostella sp.)、新月拟菱形藻(N.closterium sp.)、角毛藻(C.mueeleri sp)、平裂藻(Merismopedia sp).和席藻(Phormidium sp)组成.浮游植物多样性指数变化范围为0.08～1.89,平均值为1.36±0.25,优势度指数变化范围为0.20～0.98,平均值为0.51±0.26.浮游动物的优势种为许水蚤(Schmackeria.sp)和臂尾轮虫(Brachionus.sp),其中,水体中许水蚤无节幼体的数量呈规律性波动,波动周期为15d.

| Abstract: | The composition and diversity of plankton of culturing pond of Litopenaeus vannamei were analysed for knowing the succession of plankton community.Results indicated that the dominant species of phytoplankton are Phormidium sp, Oocystis borgei, Cyclostella sp, N.closterium sp, C.mueeleri sp, Merismopedia sp and Chlorella sp in pond.Range of diversity index is 0.08-1.89, average value is 1.36±0.25; range of dominance index is 0.20-0.98, average value is 0.51±0.26.Dominant species of zooplankton are Schmackeria Sp and Brachionus.sp.The amounts of nauplius of Schmackeria Sp fluctuate regularly and the period of changing is 15 days. |
