A Study on the Ichthyofaunal Status of an Oxbow Lake of Eastern Himalayan River of Assam, India

Abstract

The status of fish fauna of Kalpani beel in the Chirang district of Assam was studied from June to December, 2016. It is an ecologically important oxbow lake. The beel is fed by flood of Manas River originating from Bhutan and an important tributary of the river Brahmaputra. A total of 55 fish species belonging to 38 genera and 21 families (under 7 order) has been recorded during the study period from the lake. Out of these, 1.81% are endangered (EN), 3.63% are vulnerable (VU), 9.09% are near threatened (NT), 78.18% are least concern (LC), 1.81% are data deficient (DD) and 5.45% are not evaluated (NE). The highest no. of species is represented by cyprinidae family (22) followed by channidae (5), Bagridae (3), Mastacembelidae (3), osphronemidae (2), cobitidae (2), Ambassisdae (2), Nemacheilidae, Anabantidae, Badidae, Gobiidae, Nandidae, Notopteridae, Claridae, Heteropneustidae, Shilbeidae, Shilbeidae, Siluridae, Synbranchidae, Belonidae and Tetradontidae (1). The present paper deals with a list of ichthyofauna, collection locality, scientific name, local name based on their locality and their conservation status as per IUCN status.
