In the present study, twenty six species of fishes were recorded from Singhiya river, Morang district, Nepal during January to August (2016). The population present status of important fish species such as Gagata cenia and Lepidocephalus guntea was found to be threatened. Macrognathus pancalus and Mystus bleekeri was to be vulnerable and Glossogobius giuris and Puntius sarana to be intermediate. The Singhiya river have been found to be influenced by harmful human activities such as deforestation, direct waste disposal, discharge of toxic substances-fertilizers, pesticides through surface run-off from the agricultural field near the river and urbanization, industrialization, use of soaps and detergents, indiscriminate fishing, pollution, waste dumping are destroying the fresh water habitat and have been found to threaten the natural environment of fish diversity of Singhiya river which ultimately lead to their extinction and must be stopped or managed in a proper way for the conservation and sustainable utilization of aquatic-bioresources of the river.
