摘要:
本文报道1990年对三道河水库浮游生物现存量和浮游植物初级生产量的凋查结果。经初步鉴定,该水库浮蝣植物有8门39属,其中以绿藻门种类最多,占总属数的49%,其次为蓝藻和硅藻;浮游动物为37属,其中原生动物12属,轮虫13属,枝角类7属,桡足类5属。经测算,三道河水库1990年4-10月浮游植物数量和生物量分别为1139ind./L和2.085mg/L,浮游动物数量和生物量则分别为1253ind./L和1.327mg/L。浮游植物初级毛生产量平均为3.950g O2/m2·d。根据估算,该水库鲢鳙鱼产力为15×104kg左右。

Abstract:
The standing crop of plankton and primary productivty of phytoplankton are surveyed in Sandaohe Reservoir, Hubei Province from April to October, 1990, The results show that there are 39 genera of phytoplankton, subordinate to 8 phyla, and 37 genera of Zooplankton, of which Protozoa, Rotifera, Cladocera and Copepoda account for 12, 13, 7 and 5 species respectively.The gross primary productivity of phytoplankton in the water column reaches 3.950 g O2/m2·d in average in the period of April to October, 1990.The mean standing crop for phytoplankton and zooplankton is separately 1139 ind./mL, 2.085 mg/L and 1253 ind./L, 1.327 mg/L.The potential annual production of silver and bighead carps may raech to 15×104 kg.The number of silver and bighead carps fingerlings (5 cm in length) to be stocked each year should be 78×104 and 143×104 respectively.
