dc.description.abstractSpatial and temporal behavior of distribution of phytoplankton of the coral reef and seagrass environment of the Palk Bay was studied during April 2002 to March 2003. A total of 133 species of phytoplankton was recorded during the study period, of which, 98 species belong to Bacillariophyceae, 15 species belong to Dinophyceae, 12 species belong to Cyanophyceae and 8 species belong to Chlorophyceae. Diatoms (57.14 to 94.10%) contributed more towards the percentage composition of different groups of phytoplankton at the two stations, followed by dinoflagellates (3.12 to 28.57%), blue-greens (2.43 to 12.5%) and greens (3.7 to 7.69%). Higher phytoplankton population density was recorded during the summer season at both stations (St.1. 62,000 cells l-1 and St.2. 55,000 cells l-1). Coral reef environment was two-fold more productive (2.10-130.21 mg C m-3 hr-1) than the seagrass environment (3.30 - 85.56 mg C m-3 hr -1). Chlorophyll ‘a’ concentration showed higher values at station 1, corresponding to the higher phytoplankton population density recorded at this station along with primary productivity.en_US
