Abstract


Phytoplankton fluctuation analyzed at two sampling regions namely Buffalo Island (Hospital area) (A) and Koddamunai
New Bridge area (B) according to seasonal variation in the year 2014. Sampling region B is a shallow area. The following
Physiochemical parameters have to be taken for estimation; Water temperature, Conductivity, Salinity, pH, Nitrate and Phosphate
were taken into the account. Samples were collected in dry (June) and rainy (November) seasons. During dry season (June)
comparatively species diversity was higher than the rainy (November) season and the physiochemical parameters also highly reduced
during rainy season. Moreover no algal bloom was recorded during the study period.
