Abstract: A comprehensive study of native fish species of five tribes, twenty families and seven orders were carried to identify and realign the genera and species during February, 2014. Cyprinids were the dominant group (43.64% out of 55 species) in the assemblage and almost all cyprinids were liberated to pools, riffles, run and with varied habitat diversity. Present work comprises of thirty-eight genera and fifty-five species. Order Cypriniformes constituted the highest species number 30 (54.55%) followed by Siluriformes 9 (16.36%), Perciformes 10 (18.18%), Synbranchiformes 3 (5.45%) whereas Order Osteoglossiformes, Beloniformes, and Tetradontiformes constituted lowest species number 1 (1.82%). A novel sp.
Pseudolaguvia nepalensis was obtained from the stream, Kasara near to its confluence with Rapti River, central Nepal. Of the 55 species, Tor tor has characterized as near threatened in IUCN Red List. Macrohabitat assessment indicated that habitat volume was a major determining factor for species diversity and abundance.
