Blue-green Algae: Diversity and Community Structure in Rice fields of Saran, Bihar

Abstract

This study aimed to characterize the abundance of BGA in various rice ecologies of Saran (Bihar) with isolate identification and diversity indices in relation to species wise distribution. These investigations were under taken during cultivation cycle of rice in the years 2020 and 2021. The density and frequency of various BGA species was evaluated with standard methods. The study revealed occurrence of particular BGA with temporal and spatial variation, whereas abundance of BGA drastically reduced in preceding period of the study possibly due to effect of environmental constraints in the Saran district of Bihar.
