Abstract:

Seasonal variations on benthic diversity and its relationship with sedimentary parameters were carried out at different locations of Puducherry estuary and coast which are heavily sewage and polluted region at Puducherry. The values of sediment TOC (Total Organic Carbon) was found to have ranged from 0.75 mgC/g to 13.26 mgC/g and the maximum percentage of clay, silt  and sand were recorded as 81.54 %, 43.90% and 94.21 % from the stations PDY-I, PDY-VI & PDY-III respectively. The value of benthic faunal density was found varied from 450-2250 Nos /m2 with maximum in station PDY-VI and minimum in PDY-III. In station PDY-VI was registered with highest species diversity index in the range of 3.735 and 5.266. The domination of particular polychaete species such as Capitella capitata, Cossura coasta, Nephtys dibranchis and Nereis capensis was found in estuary (PDY-I and PDY-II) because these species were found to withstand for the direct impact of organic and inorganic pollution. A significant discrimination of species composition was noticed on the benthic population between estuary and coast due to the differential in exposure by the macrobenthos for the pollutants. The present studies recommend that the above polychaete species can be considered as indicator species for organic pollution.
