摘要
1986~1987年对丹江口水库浮游生物调查结果表明:该水库浮游植物以蓝藻门、绿藻门、硅藻门种类较多;浮游动物有轮虫、原生动物、枝角类、桡足类等。浮游动物和浮游植物月平均密度分别为1.078×106个/l和4.940×103个/l,月平均生物量为1.603mg/l和0.646mg/l。另外,作者还分析了各采样点及其不同采样时间的浮游生物的差异。该水库浮游生物所提供的鱼产潜力分别为:鲢1293.6万kg、鳙785.9万kg;鱼种投放量为39225.4万尾,平均每亩投放4寸鱼种422尾(鲢309尾、鳙113尾)。
The resource of Plankton of Dan Jiangkou reservoir Was Surveyed in 1986-1987. The results indicated: Cyamophyta, Chlorophy and Bacillariophyta were its main Phytoplankton, there were four kinds of Zooplankton in this reservoir. The biomass of Phytoplankton and Zooplankton were 1.603 mg/l. and 0.646 mg/l respectively. Auther also discussed the difference of biomass, density according to site and time. Fish productivity of Corp (Hypophthalmichys molitrix) and big-head silver Cavp (Aristichthys nobils) were estimated.
