Abstract: This study was the first effort to illustrate the length-weight relationship (LWR), condition factor and sex ratio of an economically important Snow trout,
Schizothorax plagiostomus collected from Neelum and Jhelum Rivers, Muzaffarabad, Azad Kashmir. The LWR of
S. plagiostomus was analyzed for both sexes with formula Log W = Log a + b Log L. A total of 330 specimens were collected during January to December, 2012 by using conventional fishing tools. The allometric coefficient b of LWR was found to be negative (b<3) all over the year. A trend line graph disclosed the declination in growth condition. The sex ratio of
S. plagiostomus was calculated as 0.15: 6.4 (male: female) which strongly favors the dominance of the female sex over male in the natural population throughout the year. It is concluded that LWR, condition factor and sex ratio of
S. plagiostomus demonstrated significant variation with environmental and physiological factors. This study would be useful to handle the adequate regulations and conservation of sustainable fishery management.
