ABSTRACT
Biological assessment is a useful for measuring the ecological quality of aquatic ecosystems since biological communities integrate the environmental effects of water chemistry. Algal and water samples were collected at monthly intervals from three sites on the river Mutha (Pune, India). The most pollution tolerant genera and species of four groups of algae were recorded from three sites on the river. Nygaard and Palmer's biotic indices have been used for the assessment of quality of the river. Phytoplankton encountered in the water body reflects the saprobic condition and, therefore, may be used as an indicator of water quality. The algal flora of polluted water bodies shows the dominance of blue green algae and diatoms like, Oscillatoria, Lyngbya, Anabaena, Microcystis, Navicula, Nitzschia, Synedra, and Gomphonema throughout the investigation many green algae like, Pandorina, Scenedesmus, Stigeoclonium, Ankistrodesmus, and Chlamydomonas, also occur abundantly and frequently.
