Seasonal Variation of Phytoplankton Community in the river Deorania at Bareilly district of Uttar Pradesh, India

The river Deorania is a good source of irrigation in Bareilly district but today this river is in much worse condition in this region. During extreme months of summer, winter and rainy seasons the qualitative and quantitative analysis of the phytoplankton community of river water Deorania were carried out for three sampling stations. The investigation was carried out during 2005-2006 and 2019-2020 at three different sampling sites. Phytoplankton are prominent primary producers in water bodies. They constitute the main food for zooplankton as well as the majority of fish. Four major groups viz. chlorophyceae, cyanophyceae, euglenophyceae and bacillariophyceae are reported in this water body. In the river deorania, a total of 12 phytoplanktonic genera were identified in the present study. chlorophyceae include 7 genera, Basillariophyceae include 2 genera, Cyanophyceae include 2 genera and Euglenophyceae include 1 genus
