The present paper deals with 51 fish species belonging to 38 genera, 20 families of 7 orders. The notable ichthyofauna of the river were Clarias batracus, Garra gotyla, Botia lohachata, Chagunius chagunio, Chaca chaca, Acanthocobotis botia, Lepidocephalus guntea. Colisa faciatus, Notopterus notopterus, Cirrhinus reba, C. mrigala, Labeo dero, L. cabasu, Salmostoma bacaila, Barilius bendelisis, B. barna, Crossocheilus latius latius, Mystus species, Ompok bimaculatus, Wallago attu, Chanda nama, Nandus nandus, Anabus testudineus, Channa orientalis, C. marulius, Catla catla, Monopterus cuchia, Clupisoma garua and Psilorhyncus sucatio. As Lohandra river was rich with ichthyofauna, the investigation of ecology and fishes of the river is recommended for the conservation of these fishes.
