摘　　要：海口地区养鱼池中浮游植物分隶于7门57属84种,浮游植物生物量大多在20—100mg/L 之间,以绿藻门的种类为主,蓝藻、硅藻、裸藻次之,金藻最少。浮游动物分隶于37属48种,浮游动物生物量多在3.0—13.5mg/L之间,以轮虫为主。浮游动物年平均生物量仅是浮游植物的1/14—1/9.5。There are 7 families which have 57 genera with 84 species of phytoplankton in the fishponds of the Hai Kou area.The biomass of phytoplankton determined by the method of calculating cell volume generally varies between 20～100mg/L,in which the Chlorophyta is perdominate,Cyanophyta,Bacil- lariophyta and Euglenophyta rank second and Chrysophyta the least. There are 37 genera with 48 species of zooplankton in the fishponds of the Hal Kou area.The biomass of zooplankton generally varies between 3.0～13.5mg/L,Rotifers is dominate. The annual biomass of zooplankton is only 1/14～1/9.5 that of phytoplankton.
