2000年对华南地区18座水库的浮游动物进行了调查。共鉴定出轮虫61种，枝角类23种，桡足类14种。最常见的轮虫属是Keratella、Brachionus、Trichocerca、Diureella、Ascomorpha、Polyarthra、Ploesoma、Asclanchna、Pompholyx和Conochilus。长喙Bosmina longirostris、德氏拟Bosminopsis deitersi、毕氏透体虫Diaphanosoma birgei、长喙透体虫D. Brachyurum和Moina micrura是水库中枝角类的典型代表。桡足类中，最常见的是Tunguidus、Neodiaptomus schmackeri和Mesocyclops leuckarti;大多数水库桡足类以莱氏桡足类为主。浮游动物物种丰富度高，丰度低是贯流水库的特点，而低丰度低的物种丰富度被发现在水库最长的保留时间：相对较高的丰度和中等的物种多样性的中间保留时间水库的区别。
The zooplankton of 18 reservoirs of South China was investigated in 2000. 61 Rotifera species, 23 Cladoceras and 14 Copepodas were identified. The most frequent Rotifera genera were Keratella, Brachionus, Trichocerca, Diurella, Ascomorpha, Polyarthra, Ploesoma, Asplanchna, Pompholyx and Conochilus. Bosmina longirostris, Bosminopsis deitersi, Diaphanosoma birgei, D. brachyurum and Moina micrura were typical of Cladocera in the reservoirs. Phyllodiaptomus tunguidus, Neodiaptomus schmackeri and Mesocyclops leuckarti were the most frequent Copepoda and M. leuckarti dominated Copepoda in most reservoirs. High zooplankton species richness with low abundance was characteristic of the throughflowing reservoir, whereas low species richness with low abundance was found in the reservoir with the longest retention time: Relative high abundance and medium species diversity were the distinction of intermediate retention time reservoirs.
