COMPARATIVE STUDY ON DISTRIBUTION OF PHYTOPLANKTONACCORDING TO SEASONAL VARIATION AT BUFFALO ISLAND(HOSPITAL AREA) AND KODDAMUNAI NEW BRIDGE AREA OF BATTICALOA LAGOON

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.
