Abstract

An ichthyofaunistic survey of River Tochi at District North Waziristan (NW) was conducted from July 2018 to December 2018 to know about morphometric measurement and relative abundance of fish fauna and impact of physico-chemical parameters on fish biodiversity and survival. A total 604 specimens were collected containing 21 species. The total reported species of fishes belong to five different orders (Cypriniformes, Channiformes, Siluriformes, Perciformes and Mastacembeliformes), seven families (Cyprinidae, Nemacheilidae, Channidae, Siluridae, Sisoridae Cichilidae and Mastacembelidae) and nine genera (Barilius, Gara, Aspidoparia, Crossochielus, Cyprinion, Cyprinus, Puntius, Cirrihinus, Labeo, Schistura, Channa, Ompok, Glypthorax, Oreochromis and Mastacembelis). Family Cyprinidae was the dominant family of the all reported families. Species Schistura affaciata is the first time report of this species from Khyber Pakhtunkhwa. Analytical results of Water quality parameters like Temperature, pH, Conductivity, Alkalinity, Salinity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total Hardness, Magnesium (Mg) Hardness, Calcium (Ca) Hardness and free CO2 reveal that all the values fall in standard range for fish life.
