Yogendra Kumar Payasi

Abstract :

<p>&nbsp;Present work was carried out to investigate the diversity and distribution of phytoplankton in the River Hiran. Samples&nbsp;</p> <div>were collected from five sampling stations, namely Kimdeshwar, Khitoula, Ghat Simariya, Khinni and Hirapur for two&nbsp;</div> <div>consective years. A total of 66 species of phytoplanktons were collected from the Hiran river. The greatest phytoplankton&nbsp;</div> <div>density from 830.4 to 4549.9 org/l was found at site S&ndash;1, while the least phytoplanktonic density 138.4 to 588.2 org/1 was reported at stations S&ndash;5.&nbsp;</div> <div>The phytoplankton represented in greatest number of Cyanophyceae and the least density of Dinophyceae. The phytoplankton represented in&nbsp;</div> <div>the order of Cyanophyceae &gt; Bacillariophyceae &gt; Chlorophyceae &gt; Dinophyceae</div>
