Ecological Studies of Algae in River Burhi Gandak at Samastipur, Bihar

Abstract

In the present investigation the algal biodiversity of river Burhi Gandak at Samastipur, Bihar was studied with reference to the algal spectrum and population density of phytoplankton for a period of two years at two Years. Two sites (I and II) were selected for the present study. Altogether 41 algal taxa at site I and 39 at site II were detected. The members of the algal taxa belonged to the three different classes viz. Cyanophyceae, Chlorophyceae and Bacillariophyceae. The annual mean average of population density of these algal taxa was found as 4035.44±435.5 u/lit at site I and 2036.16±660.25 u/lit at site- II. The continuous presence of some pollution tolerant algal taxa in river water indicates that the river water is getting rapidly polluted.
