The current study was started from March to December 2001 to investigate the seasonal variations in biological parameters and biodiversity in water of River Indus at Ghazi Ghat (D.G. Khan) by analyzing the frequency of occurrence, relative abundance and diversity index of planktonic life. Density and diversity of Planktonic life was used as a measure of water quality. Phytoplankton were abundant as compared to Zooplankton. 125 Phytoplankton genera were recorded. Among these 17 of Cyanophyta, 3 of Cryptophyta, 1 of Pyrrophyta, 10 of Chrysophyta, 5 of Xanthophyta, 18 of Bacillariophyta, 8 of Euglenophyta, 49 of Chlorophyta, 4 of Charophyta, 1 of Rhodophyta, 7 of Macrophyta and one genera of filamentous algae. 44 genera of Zooplankton were observed including 22 of Protozoans, 10 of Rotifers, 6 of Cladocera and 6 of Copepoda.
