Abstract

The living and dead foraminiferida in the substrate samples collected from 14 Stations in the Araniar River estuary along the east coast of India from June 1978 to May 1979 have been studied quantitatively. The average salinity ranges from 23.5 to 38.5% and it is considered to be the principal controlling ecologic factor that limits the distribution and abundance of foraminiferida. The pattern of distribution of foraminiferida is also explained in terms of deposition of fluviatile sediments in the estuary. The abundance and living/dead ratios of foraminiferida tests have been compared with those recorded in the nearby Dugarazupatnam and Pennar estuaries.
