Rotifer Diversity of Osmansagar Reservoir, Hyderabad, Telangana, India

Rotifers are one of the most important components in zooplankton community. They play a crucial role in interlinking food chain in the aquatic ecosystem. They are considered to be one of the most sensitive indicators of water quality (Sladecek, 1983; Ali et al., 1990; Pontin and Langley, 1993). It is of the opinion of many researchers that the rotifer species composition and their abundance can be used as indicators of trophic status (Berzins and Pejler 1989; Matveeva, 1991; Duggan et al., 2001; Ejsmont-Karabin, 2012).
