Prevalence of Macrobrachium gangeticum (Macrobrachium choprai) Bate. in Siang river at D’Ering wild life sanctuary, Arunachal Pradesh (a biodiversity hot-spot)

Abstract

The paper deals with the extended distribution of Macrobrachium gangeticum (which is a large sized prawn) in Siang river at D’ Ering Sanctuary of Arunachal Pradesh. Siang river is a fast flowing river and availability of the M. gangeticum to this river exhibits its capacity to resist the water current; however, it was collected during winter months when the water current was comparatively low but still not much low. M. gangeticum was identified by its large size and presence of dorsal elevated rostral keel.
