Rotifers are the most diversified group of Zooplanktons and play important role between the autotrophs and other heterotrophs. It forms an important links in food chain. Rotifers found abundantly in Burhi Gandak. A total of 14 and 12 species of rotifers were recorded in point I & II respectively. The first (108 U\L) and second (118 U\L) peak was recorded in December 2018 and May 2019 respectively. The dominant rotifer species was B. Caudatus (22 U\L) and (24 U\L) was recorded in May 2019 and June 2020. Keratella tropica was the second dominant speices. A total no. of 18 and 24 species was collected in first and second point during the study of diel variation. The data collected co-related to study the condition of river Burhi Gandak in the light of available literature.
