The current work was involved in the occurrence and abundance of the cyanobacteria strains present in the predominant water outlets present in the city Prayagraj, for analysing the types of strains found during the different seasonal interims. The cyanobacteria distribution in water from water samples are collected from above mentioned locations during the January, May and September months in the year of 2013 and 2014. The cyanobacteria population in the vicinity was analyzed using the physico-chemical factors like pH, temperature, electrical conductivity, total phosphorus, inorganic phosphorus, ammoniacal nitrogen, nitrate, nitrite, iron, zinc, Manganese, Copper and arsenic and algal flora (qualitative) were also studied and compared their variations among the three different freshwater bodies. In addition, biological parameters such as primary production gross primary productivity, net primary productivity and community respiration rate were also studied. Total 11 species of cyanobacteria were isolated. It was observed that the distributional patterns of the cyanobacteria were related with that of the physico-chemical parameters of the water sample. Since there was no significant difference in the parameters of the sampling sites, a few cyanobacterial strains were found to be dominating, followed by co-dominating and peripheral species which were found to be common in all the sampling sites. This ultimately shows that there is no significant change in the distribution of the cyanobacterial strains in the current area of study under the same equatorial region.
