The community structure of plankton was studied in relation to physico-chemical characteristics of the river Talar polluted by industrial effluents and domestic sewage from November 2008 to July 2009. In addition, seasonal changes in phytoplankton and zooplankton populations and species abundance were also determinate. The dominant phytoplanktonic algae determined were Oscillatoria, Anabaena, Nostoc, Spirogyra, Pediastrum, Navicula and Nitzschia. The dominant zooplanktonic organisms determined were Paramecium, Daphnia, Cypris, Keratalla and Arachinous. The present study on ecology and the surface water of this fresh water river covered a number of aspects, beginning from abiotic and biotic parameters to pollution assessment and thereby reveals a true picture of the water quality of the river .
