Schizothoracids (snow trouts) are indigenous Cyprinids in the Jhelum river system in Kashmir. Among the snow trouts, Schizothorax labiatus McClelland is one of the economically valuable and an important ood fish with wide market demand. A study on length-weight relationship and condition factor of Schizothorax labiatus was carried out for a period of twelve months (12) on 310 samples collected randomly from river Jhelum Kashmir in order to determine the growth pattern and health of the fish. The length weight relationship of the fish indicated negative allometric growth pattern of the fish (b<3), the overall regression length-weight relationship equation for males, females and pooled data of both the sexes was obtained as Log W = - 3.894+ 2.598 Log L (r = 0.863), Log W = - 3.777 + 2.543 Log L (r = 0.799) and Log W = - 3.849 + 2.578 Log L (r = 0.845) respectively, indicating positive correlation between length and weight of the fish. Index of well being or condition factor (Kn) indicated good condition of the fish as ascertained by mean condition factor value for males & females as 1.4 and 1.5 respectively. The present study could be helpful in conservation and management of this indigenous snow trout in river Jehlum.
