Surveys on the distribution of fish fauna in Keniam River Taman Negara Pahang were conducted from 16th-22nd March 20II. Fish were sampled from 12 stations from 3 different zones of the river namely, the upper reaches,middle reaches, and lower reaches. A total of 17 fish species belonging to 4 families were recorded. Analyses based on the number of individuals caught showed that 82% of total catch was represented by the Cyprinids. Mystus nemurus and Mystacoelucus marginatus were the most distributed within the Keniam River being present in the upper middle and lower reaches of the rive!: Species richness (Margalef's D) for fish ranged from 2.33 to 2.96 while the Shannon-Weiner (H') Diversity index ranged from 1.80 to 2.07. The upper reaches recorded highest diversity (H'=2.07, D=2.96) ascompared to the other zones of the Keniam River Approximately 82% orJ4 species of the fishes sampled were juveniles or sub adults based on the ratio of their mean standard length to their maximum attainable length.Keyword: Freshwater fishes, distribution, species richness, species diversity
