During the month of May 2016 to September 2016. 50 Fishes per species sample were collected from Chambai dam district Karak, Khyber Pakhtunkhwa. Length weight relationship shows a wide variation in results for Labeorohita, Hypophthalmichthys molitrix, Catla catla average length 30.48cm, 17.78cm, 10.16cm and the average weight were 160g, 26g and 15g respectively. The weight-length relationship of Labeorohita, Hypophthalmichthys molitrix, Catla catla could be considered as very useful in fisheries research, fish biology and ecology.
