Core samples of sediments were collected during January, March. April, May, June, July, September and November, 1970 from stations located along the length of a tidal creek near Pudimadaka near Visakhapatnam, east coast of India. Samples of water just above the sediment surface were collected and analysed for salinity and dissolved oxygen. During sampling of the sediments, the top one centimetre of the sediment core was preserved in 5% formaldehyde and later in the laboratory dead and living foraminiferal populations were differentiated using the Rose Bengal technique. Ammonia beccarii, Ammonia beccarii var. tepida , and Quinqueloculina seminulum dominate among the calcareous species while Ammobaculites agglutinans, Textularia agglutinans dominate among the arenaceous species. Among several ecological factors that control the variety and abundance of living foraminiferal fauna, chlorinity of the waters appear to play a determining role in the area under study.
