|Abstract:||Fifteen surface sediment and bottom water samples were collected from the Adyar river estuary, Chennai, starting from the mouth of the river upstream. Twenty-six species belonging to 23 genera have been encountered, of which Caudites javana and Tanella gracilis were abundant and widespread in the study area. The distribution of the species in each sample is given. Water parameters such as temperature, salinity, dissolved oxygen and sediment characteristics like CaCO3, and organic matter content of each sample were estimated and correlated against the ostracod population recovered in the respective sample. Sand, silt and clay ratios have been estimated and plotted on trilinear diagrams. The four sediment types represented in the study area are sand, siltysand, claysilt and sandyclaysilt. The distribution of ostracods in the Adyar river estuary seems to be controlled by salinity and substrate.|
