Abstract :

The biomass and species composition of macrobenthos was studied in three substations (Sheva creek, Peerwadi coast and Dharamtar creek) along Uran coast, Navi Mumbai. The intertidal region was surveyed during spring low tides for species diversity and biomass of macrobenthos monthly from June 2013 to May 2015. Number of selected macrobenthos present in one [m.sup.2] area was considered for assessment of biomass (g/[m.sup.2]). The study recorded a total of 170 species of macrobenthos belonging to 119 genera, 83 families, 44 orders and 17 classes. Results of the present study showed that along Uran coast, biomass of U. annulipes and P. cingulatus showed highest values and have dominated the T. carinifera and N. oryzarum. The degree of biomass of selected macrobenthos can be put as U. annulipes (76.406) P. cingulatus (47.692) T. carinifera (20.626) N. oryzarum (17.831). Water temperature, salinity, type of sediment, carbon flow, abiotic and biotic factors, quality and availability of food, smaller grain size and higher organic content in sediment are the limiting factors that determines the biomass of intertidal invertebrates. Variation in biomass of macrobenthos suggests that the coastal benthic community is under anthropogenic stress due to the Port activities, pollution-induced disturbances due to disposal of untreated waste, coastal dredging, oil spillage, coastal tourism, human settlement on the coast and fecal pollution. The data on biomass of macrobenthos provided can be used as the baseline for future research.
