Abstract
A study was undertaken to record the monthly fluctuation in phytoplankton population in Vallimalai, Jlankandeswarar, Sri Margabandeswar and Simmaulam temple ponds water samples of Vellore district, Tamil Nadu, India, for a period of August 2020 to July 2021. Four groups of phytoplankton were recorded in the samples. They are i. Diatoms, ii. Green algae, iii. Blue greens and iv. Euglenoids. During the study, a total of 67 species, belong to 38 families and 57 genera were recorded in respective study area. Diatoms were found to be the dominant group with 52 species. Green algae formed second dominant group with 25 species. Blue greens came next in the order with 10 species followed by euglenoids with 4 species in the study area. With respect to population density, in station-1 the density varied from 225 to 5,450 cells/L with minimum during July-2020 (premonsoon) and maximum during February-2020 (post monsoon), in station-2, the population density it fluctuated between 103 and 7,346 cells/L with minimum during December-2020 (monsoon) and maximum during February-2021 (summer), in station-3, fluctuated from 102 to 7,961cells/L with minimum during April-2020 (summer) and maximum during May-2021 (summer) and in station-4, density of phytoplankton varied from 525 to 7.240 cells/L with minimum during March-2021 (post monsoon) and maximum during January-2021.
