The Kodungallur-Azhikode Estuary (KAE) is part of the Vembanad wetland ecosystem in south-west coast of India that has recently been designated as the Ramsar site. Modern aquaculture, agriculture and other human activities in the catchment area export huge amounts of organic and inorganic wastes into the KAE. In this perspective, influences of anthropogenic activities on water quality and phytoplankton production in the KAE were studied at multiple sites from July 2009 to June 2010. The linear correlation with salinity (r2=0.179, P<0.01), pH (r2=0.195, P<0.01,) and redox potential (Eh) (r2=0.188, P<0.01) was found to be significant with Chlorophyll-a (Chl-a) and negative correlation with turbidity (r2=-0.212, P<0.01, N=168), nitrate (r2=-0.297, P <0.01, N=168), and total dissolved solids (TDS) (r2=-0.266, P<0.01, N=168). The present study showed annual average gross .. View More»
