Based on the importance and crucial role in biosphere, studying fish is a debatable issue. Biodiversity refers to the number of different species living in an ecosystem. The current research survey was undertaken to study fish diversity of River Barawal District Dir Upper Khyber Pakhtunkhwa, Pakistan from April to September 2016. Fish samples were collected using cast nets, scoop net, hooks, rods and mesh cloth. Identification of the collected samples was performed studying various morphometric measurements and meristic counts. During this study seven different fish species were collected belonging to two orders; Siluriformes and Cypriniformes and three families; Sissoridae, Nemacheilidae and Cyprinidae. Family Sissoridae was the dominant family represented by 3 species viz; Glyptothorax stocki, Glyptothorax naziri and Glyptosternon reticulatum. Family Nemacheilidae represented by two species i.e. Schistura curtistigma and Triplophysa microps while Cyprinidae was represented by two species Racoma labiate and Crossocheilus diplocheilus. If the water quality and maintenance of this river is properly monitored, it can harbor large number of fish species.
