Abstract :

The present study was carried out on Ghuma lake of Ghuma village. Ghuma village is situated in Daskroi taluka of Ahmadabad district, Gujarat State. Ghuma is 16.4 km far from its district place Ahmadabad. Nearest town is Sanand and is 12.8 k.m. far from Ghuma village. Current population of Ghuma village is about 15000. Ghuma lake is situated on western side of the village. The plankton were collected, counted and were identified by using the method suggested by APHA (1995) Prescott (1970) and FRESH WATER BIOLOGY (W. T. Edmondson–1959). The plankton were counted by using Sedgwick Rafter counting cell. Different class such as cyanophyceae, chlorophyceae, bacillariophyceae, euglenophyceae, cilliata, cledocera, copepod and specimens from phylum rotifera were identified during the study. Among all these classes the listed phytoplankton such as Oscillatoria Sp., Tetraedron Sp., Navicula sp., Nitzschia sp, Euglena Sp. and zooplankton such as Ceriodaphnia sp., Cyclops sp., Tropocyclops sp., Brachionus sp. and Platyias sp. were recorded as a dominant genera in Ghuma lake. The study was carried out monthly but was tabulated seasonally by using statistical method.
