Journal Title: STAR Journal - Year 2013, Vol 2, Issue 2
Abstract
This study was carried out in Gowrikere tank of Anandapura village of Sagara taluk of Shivamogga city, Karnataka on phytoplankton diversity and density for a period of twelve months from January to December 2012. A total of 48 species belonging to 37 genera of phytoplankton were recorded. Relative abundance of phytoplankton in tank showed maximum of Bacillariophyceae (27.08%), followed by Chlorophyceae (22.91%), Cyanophyceae (20.83%), Desminds (18.75%) and Euglenophyceae (10.41%). The highest density of phytoplankton was recorded during summer season. Chlorococcales varied with peak density (10925 org. /l (Organism/Litre)) during May and lower in the month of December (7034 org. /l). Diatoms ranged from 1981 org. /l (September) to 4432 org. /l (January). Desmids varied with peak density (83 org./l) during February and lower in the month of July (32 org. /l). Euglenoids population showed maximum density during the month of March (3091 org./l) and minimum with 1973 org./l in the month of July. Density of blue greens recorded a maximum of 9114 organism / in April and a minimum of 7115 organism/l during the month of December. Pollution tolerant species such as Scenedesmus quadricauda, Coelastrum microporum, Phacus longicauda, Trachelomonas robasta and Microcystis aeroginosa were recorded.
