| 摘 要： | 研究了2009年5-9月鲟亲鱼养殖池塘中浮游生物的种类组成，细胞数量、优势种组成和随季节的变化。结果显示：鲟亲鱼的活动导致养殖池塘沉积物再悬浮，水体透明度较低。浮游植物的种类组成以绿藻门（Chlorophyta）的月牙藻（Selenastrum spp．）和小球藻（Chlorella spp．）等小型个体为主，浮游植物密度1．0883×lO^7ind．／L—1．5662×lO^7ind．／L，生物量14．6438～19．2535mg/L。浮游动物以轮虫（Rotifera）和桡足类（Copepoda）为优势种群，浮游动物密度162．0000ind／L～560．0000ind／L，生物量0．3795～1．5482mg／L。研究显示，鲟亲鱼的活动是决定池塘浮游生物的群落结构变化的重要过程之一。

| Abstract: | The changes in plankton species community, cells abundance, dominate species and seasonal variation in brood sturgeon culture ponds were studied from May to September in 2009. The results showed that the sediment resuspension caused by brood sturgeon＇s daily movements induced Secchi depth transparency stable at low levels. The Chlorophyta Selenastrum spp. and Chlorella spp. were found to be dominant in phytoplankton community. The abundance of phytoplankton were found to range from 1.0883 × 10^7ind./L to 1.5662x 10^7ind./L, and biomass range from 14.6438 mg/L to 19.2535 mg/L. The Rotifera and Copepoda were dominant in zooplankton community. The abundance of zooplankton was ranged from 162.0000ind./L to 560.0000 ind./L ,and biomass from 0.3795 mg/L to 1.5482 mg/L. The changes in plankton community structure were attributed to the daily movements of the brood sturgeon. |
