Kanpur, Dist. Kanpur - 208001, U.P. Abstract A study was carried out on the occurrence of Cyanobacteria in relation to certain physicochemical parameters in Mahil Pond of Orai District, U.P. The study was conducted over a period of 11 months from June 2011 to May 2012. Out of the different Cyanobacteria strains, 8 were identified to be of major presence in the pond. The peak production of Cyanobacteria was in the month of October 2011. There were fluctuations of some physicochemical parameters. Change of Water Temperature, Dissolved oxygen, Total dissolved Solid and Electrical Conductivity along with pH of the pond were also studied. Key words: Water Quality, Physicochemical Parameter, Cyanobacteria, Mahil Pond. Inroduction In the last decade much focus and attention has been given on understanding and evaluating many of our water reservoirs. Concentration assessment of various physicochemical parameter play a great role in understanding the quality of a water body. Recent study suggest that biological activities also play a key role in manipulating the properties of a water body and its effects on an aquatic ecosystem (Knight et al 1917) 16 . Out of the many microbial species found in any water body are Cyanobacteria too. Their presence and effect in a water body influences the ecosystem at large. The byproduct produce from cyanobacteria have wide range of applications. Some studies have evaluated the toxic nature of these byproducts, furthermore such toxins have been seen to act as algaeside, herbiside and insecticide (John P., Berry et al) 12 . Effect of Cyanobacteria and its correlation with aquatic life along with household uses of such water bodies are yet to be studies in depth.
