Abstract: The fish of the lower Nun River was sampled for 12 months to determine species distribution (surface and vertical distribution) and abundance using small gill nets of 8, 12 and 15 mm. A total of 11, 156 specimens were caught consisting of 25 species belonging to 14 families. In terms of species diversity, Characidae (16%), Schilbeidae (16%) and Cyprinidae (12%) were the highest. Parailia pellucida was the most abundant (71.30%). There was no significant difference in the longitudinal and vertical variation of the species.
