Abstract

The coastal waters of Mumbai indiscriminately receive tremendous input of untreated domestic wastewater and industrial effluents Continuous environmental monitoring of the coastal and marine areas off Mumbai for the period 1996-2001 showed spatial and temporal variations based on seasonal and tidal fluctuations. The W in the creeks frequently recorded nil values. particularly during low tide. Salinity was observed to be very low in the creek and nearshore areas during low tide and monsoon. The plankton and fishery showed a decline in their diversity and catch over the years. From the study area, 25 groups of zooplankton were recorded. Experimental fishing revealed the presence of 96 species of marine living resources representing seaweeds, corals, gorgonids, echinoderms, crustaceans, molluscs. pelagic & demersal fishes and other groups. Microbiological studies indicated fluctuations during premonsoon, monsoon and postmonsoon periods particularly in total coliforms, faecal coliforms and faecal streptococci that indicate faecal contamination.
