Abstract



The macrobenthic study of mangrove mudflats along shallow region of Thane creek revealed dominance of sea anemone, Acontiactis gokhaleae at HLWM of Vitawa station near geomorphic head of the creek. This station is also characterized by lower population density of polychaetes suggesting predator-prey relationship. The abundance of sea anemone has been correlated with currents, salinity and sediment organic carbon but does not show any substrate specificity. Low sediment N/P ratios indicate domestic sewage pollution even though C/N ratios were lower due to less concentration of humic acid. Hence they can be treated as indicator of biofouling
