摘要： 通辽地区精养鲤池塘浮游植物生物量为23.6～53.8mg/L,以绿藻门绿球藻目中的栅藻、绿球藻、小球藻、空星藻属等常见种类数量最多，占总生物量的43%;隐藻门、裸藻门中的一些种类亦具一定数量，占浮游植物总生物量的37%.浮游植物的初级生产量的均值为402.6kg/hm2·d,每年可提供1553.4kg/hm2的鲢鳙产量。

Abstract: The biomass of phytoplankton in intensive cultivated carp ponds in Tongliao was between 23.6-53.8mg/ L.Scenedesmus,Chlorococcum,Chlorella,Coelastrum etc,which were contained in Chlorococcales were more in there ponds,and the amount of these species in Chlorococcales was 43% in that of the total biomass of phytoplankton.Cryptomonas,Euglena etc,which had flagellum also had certain amount,and was 37% in that of the total phytoplankton biomass.The primary productivity was 402.6kg(wet weight)/ h•m2•day,and it could provide 1553.4kg/h•m2•day output of the silver and bighead carp.
