摘要：Phytoplankton contributes significantly to the productivity of aquatic ecosystem. Any effect on the quality of water is reflected in the community structure and diversity of phytoplankton. The present communication deals with the qualitative and quantitative analysis of phytoplankton in Western Yamuna Canal (WYC) and Yamuna river which receives industrial effluents and domestic sewage from point and non-point sources. Odum algal index was also used for analyzing the constituent diversity of algal species and monitoring the water quality. Sixteen taxa from western Yamuna Canal and thirty five taxa from river Yamuna have been observed belonging toChlorophyceae, Bacillariophyceae, Cyanophyceae and Dinophyceae. The abundance, distribution, total population, group percentage and species diversity were studied and correlated with pollution indicating water quality characteristics. Species diversity values indicated a decrease from pre effluent point to effluent discharge channeland post effluent discharge point. Maximum value of Odums algal index was observed for Cladophora spp. at WYC and for Micrasterias spp. and Navicula spp. at river Yamuna indicating them as tolerant taxa.
