dc.description.abstractThe foraminiferal gradient in the bay indicates high foraminiferal productivity with large sized, mostly megalospheric, robust, many-chambered @iAmmonia@@, with @iElphidium@@ sp., @iFlorilus boenum, F. scaphus@@ followed by miliolids in the littoral zone, and smaller sized @iNonionella@@ sp., @iFursenkoina pontoni, Bulimina marginata@@ and @iBrizalina striatula@@ and others being dominant in the distal zones. This property of certain species restricting themselves to the least affected zone is suggestive of their response to the effect of effluents and thus being absent near the outfall area. The total foraminiferal number (TFN) and the total species number (TSN) represent the abundance and the index of diversity besides spatial heterogenuity. The organic carbon content in the sediment is inversely proportional to the abundance of the benthonic populations. Living foraminifera are very useful in establishing zones of effects of pollutants in a region. Correlation coefficient between TFN and TSN on the one hand and between TFN with the nature of the substrate in relation to the radial distance from the mouth of the discharge point on the other, appears to be very erratic. The relative sensitivity of the benthonics nearer the outfall area is more positive than could have been expected otherwise
