The neglect had lead to severe pollution of the lakes affecting the ecology as well as the livelihood of the locals dependent on the lakes. The Thane Municipal Corporation started the process of bioremediation of lakes in Thane city from the year 1999 by using selected, preadapted, nonpathogenic microbes. Lake Kacharali was the first one to undergo the process and prior to the bioremediation process the lake was physically cleaned of all the floating macrophytes. The physico-chemical parameters to assess the water quality along with the phytoplankton and zooplankton to understand the biological diversity were undertaken from the beginning of bioremediation process in January 1999 till June 2000. Among the zooplankton Rotifera comprise the integral part of the food chain and are important link between the nanoplankton and the carnivorous zooplankton. They play a major role in cycling of organic material and constitute a large portion of the diet of larval fish. During the study 13 species of the rotifera were observed and varied from 50 ind/100 L to 5876 ind/100 L. The diversity of rotifers is indicative of the ecological factors of the water body. The bioremediation process was observed to be successful as the water quality and rotifer diversity revealed mesotrophic conditions from the initial eutrophic conditions.
