Journal Title: Universal Journal of Environmental Research and Technology - Year 2016, Vol 6, Issue 2
Abstract
The present study was designed to study the seasonal variation and diversity of rotifers from the Shahanoor dam reservoir, district Amravati, Maharashtra. In the study period from January 2011 to December 2013, total 25 species of rotifers belonging to 14 genera were identified. Keratella tecta was the most dominant rotifer, followed by Keratella serullata and Monostyla copies. Percentage and population of each species of rotifer was studied. Further seasonal variation among the rotifers was also noted. Highest number of rotifers were recorded in summer season while lowest rotifer count was in winter season. Rotifer species like Keratella tecta, Keratella serrulata, Monostyla copies, Monostyla pyriformes, Monostyla clastocerca, Lecanae mira, Lecanae flexilis were abundant while Collurella uncinata, Harringia rosa, Trichocera and Vonoyella globosa were rarely found throughout the study period. The main objective of the present study was to assess the composition of rotifers and determine their response to seasonal variations. As the water from this reservoir is supplied to different villages nearby, such study will help to know the water quality and general environmental status of water body.
