RESUMO

Rotifers are usually considered to be useful indicators of water quality. Due to high population turnover rates, rotifers are particularly sensitive to changes in water quality. Their community structure not only allows estimates of the level of pollution, but also can indicate the trend of general conditions over time. This study was conducted by investigating rotifer species composition and dynamics, as indicators of lake trophic status. The qualitative and quantitative analysis of the rotifers of Lake, are based on materials collected monthly between February 2008- January 2009. Thirty-five species were recorded indicating a fairly rich quality. When the annual abundance of species was taken into consideration Brachionus and Keratella species were determined as dominant species. Dominance of these species indicates onset of eutrophication in the ecosystem. These species were observed in most months of the year and are well observed in their annual abundance.
