| 1 | Sea anemone, Acontiactis gokhaleae as biofouler in the Mangrove mudflats along Thane Creek 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 Source: Mishra, V.; Quadros, G.; Ullal, V.; Gokhale, K.S.; Athalye, R.P. Mahasagar. 27(1); 1994; 73-78. 0879. | ||
| 2 | Macrobenthos from the mudflats fo Thane Creek, Maharashtra, India Thane Creek, which extends 28 km northwards from Bombay Harbour joins the Ulhas River near Thane city. It has mangrove mudflats which are mainly tide dominated, but they receive large amounts of domestic and industrial effluents. This paper reports on the invertebrate fauna including polychaetes, gastropods, bivalves and sea anemones, collected over one year from the mudflats of the Thane Creek upstream of Thane city Source: Athalye, R.P.; Gokhale, K.S.

| 3 | Mangroves of India: State-of-the-art report (1987-1996) Mangroves are the salt tolerant forest ecosystems found mainly in tropical and subtropical intertidal regions of the world. Indian mangroves are distributed in about 6,740 sq. km which constituted 7% of the world mangroves and 8% of the total Indian coastline. A total area under the mangrove vegetation was recorded on the east coast 70%, on the west coast 12% and the bay islands of Andaman and Nicobar 18%. Ecology and faunal association of mangrove habitats have been studied in several mangrove areas. The plants which grow there have to encounter higher salinity, tidal extremes, wind velocity, high temperature and muddy anaerobic soil. The plants are well-adapted to the changes in climate, the rise in sea levels and to the incidence of solar ultraviolet-B-radiation. Other aspects such as microbiology, flora, fauna, utilization, biochemistry, plankton and degradation which are related to mangroves have been studied. Conservation and management of mangrove genetic resources in an imperative need to prevent deforestation, coastal erosion and fall in fishery resources. The same is also addressed Source: ENVIS Publ.
