Open publisher page 3 citations

Abstract

Estuarine water quality and species composition of phytoplankton was studied from July 2011 to June 2012 at four locations in Manakudy estuary .Water temperature, pH, salinity, DO, BOD levels were detected. 57 species of the phytoplankton were identified from all the locations. Diatoms were the most diverse group with 33 species followed by the Green algae (12); the blue green algae (7) and din flagellates (5) species. The percentage distribution of Bacillariophyta (74.23%) in station 2 contributed more, among all the stations. during the study period. The observation from the study revealedi that phytoplankton density is not very good predictors for the changes in water quality in the study area.
