The present study makes a record on the density and seasonal variations of phytoplankton in a perennial pond ecosystem of Tripura during a period from March 2019 to February 2021. The present observation recorded the presence of 14 species of phytoplankton in the studied perennial pond. The percentage composition of different families under which different phytoplankton species belongs was noted as well as percentage composition of each phytoplankton species was also noted. Amongst the density of the phytoplanktonic groups, the density of the Chlorophyceae was highest in winter (1153 ind/l) and lowest in monsoon (379 ind/l), density of the Cyanophyceae was found to highest in monsoon (613 ind/l) and lowest in summer (139 ind/l) while the density of the Bacillariophyceae was highest in winter (317 ind/l) and lowest in monsoon season (63 ind/l), Euglenophyceae showed its highest density during winter (67 ind/l) and lowest density (11 ind/l) in the monsoon. Notable physico-chemical factors of the studied pond were also noted during the occurrence of phytoplankton. The present study infers that densities of different phytoplankton groups may vary with different seasons of the year due to dynamic nature of the aquatic ecosystem and might be also due to optimal condition in the physico-chemical parameters of the studied lentic ecosystem.
