Abstract :

 Rivers have been playing an important role in the conservation of rich varieties of fishery resources since the days of yore. The present study was conducted between January 2012 to January 2014 to assess the diversity and abundance of fish fauna of the dolphin populated three zones (Kukurmara ,Jiakur and Dorabeel confluence) of river Kulsi (a tributary of the River Brahmaputra), Kamrup District, Assam. The result of present investigation reveals the occurrence of 58, 56 and 63 fish species belonging 7 orders, 20 families and 38 genera from Kukurmara, Jiakur and Dorabeel confluence respectively. A total of 944, 874, 905 individuals were caught from 3 zones. Diversity indices such as Simpson’sindex(d), Shannon–Weiner index (H), Margalef ’s species richness (R) were recorded as –– (d)= 0.026(zone–I), 0.027(zone–II), 0.029(zone–III), (H)=3.811(zone–I), 3.781(zone–II) and 3.732(zone–III) and (R)=9.051(zone–I), 8.577(zone–II) and 8.817 (zone–III) respectively for the three Dolphin habitat zones. Estimates from this indices show low fish diversity, composition, and richness in the Dolphin populated habitat.
