Abstract
This work was carried out to investigate the physico – chemical characterisation and
phytoplankton diversity oflentic water-body. To analyse the physico – chemical and
phytoplankton diversity, the water sample was collected from different locations
Gopalaswamy Honda which is located in Chitradurgafort . This study was carried out during
Januvary-2019 to December-2019. Many physico-chemical parameters were studied such as
Temperature, pH, acidity, alkalinity, chloride, DO, BOD, etc. Among the various paramaeters
studied, DO and BOD plays significant role on phytoplankton diversitry. According to
present investigation work the average DO and BOD were 7.48 mg/L and 3.6 mg/L
respectively, it is concluded that BOD is not at all harmful to phytoplankton because DO is
higher.Duringphytoplanktonic study, it is observed that cyanophyceanmembers were
dominant over other groups. Phytoplkanton are more sensitive to pollution than other
organisms and used commonly for water quality characterisation Phytoplankton study and
monitoring are useful to control the physico-chemical and biological conditions of water.
