摘要
:1997年 4月 5日至 1998年 9月 1日对山东高青盐碱池塘浮游动物的种类组成和季节变动进行了研究。结果表明 ,高青盐碱池塘含盐量变动于 1.36～ 2 0g·L-1,总碱度变动于 2 .4～ 7.2mmol·L-1,pH值 8～ 9。浮游动物主要是淡水耐盐种或喜盐种 ,一些是典型的盐水种。浮游动物优势种有团焰毛虫、双环栉毛虫、锥瓶口虫、瓜形膜袋虫、旋回侠盗虫和绿色前管虫 (原生动物 ) ;褶皱臂尾轮虫、暗小异尾轮虫、萼花臂尾轮虫、角突臂尾轮虫、壶状臂尾轮虫、卜氏晶囊轮虫、简单前翼轮虫、角三肢轮虫和针簇多肢轮虫 (轮虫 ) ;微型裸腹和长肢秀体(枝角类 ) ;细巧华哲水蚤、近邻剑水蚤和台湾温剑水蚤 (桡足类 )。
The species composition and seasonal succession of zooplankton in saline alkaline ponds in Zhaodian Fish Farm, Gaoqing County, Shandong Province, from 5 April in 1997 to 1 September in 1998, were studied.The results indicated that salinity ranged from 1.36 to 20 g·L -1 , total alkalinity changed from 2.4 to 7.2 mmol·L -1 , pH changed from 8 to 9, the zooplankton in saline alkaline ponds were composed by freshwater salt tolerance species or halophile species, and some of them were halobiont species and which usually occurs in freshwater. Dominant species of zooplankton were Askenasia volvox, Didinium nasutum, Lagynophrya conifera, Cyclidium citrullus, Strobilidium gyrans and Prorodon viridis(Protozoa); Brachionus plicatilis, Trichocerca pusilla, Brachionus calyciflorus, B. angularis, B. urceus, Asplanchna brightwelli, Proales simplex, Filinia cornuta and Polyarthra trigla(Rotatoria); Moina micrura, Diaphanosoma leuchtenbergiatum(Cladocerans); Sinocalarus tenellus, Cyclops vicinus, Thermocyclops taihokuensis (Copepod). The biomass of zooplankton in the control ponds and new ponds were higher than that in other fish culture ponds.
