| Abstract | ||||
| Length-weight relationships are of great importance in fishery assessment studies since it provides vital information about the growth of fishes, reproductive biology and general well-being of fish in their respective habitats. In the present investigation a total of 158 specimens of Schizothorax richardsonii (N=30), Garra gotyla (N=28), Botia biridi (N=25), Crossocheilus diplocheilus (N=25), Mastacembelus armatus (N=24) and Tor putitora (N=26) were collected during June, 2017 to October 2018 from different sites of the River Poonch of Pir Panjal Himalayan region, with the help of local trained fishermen by using cast and gill nets. The results revealed that positive allometric growth (b>3) for S. richardsonii, C. diplocheilus and M. armatus, while negative allometric growth (b<3) were noted in G. gotyla, B. biridi and T. putitora. The ‘a’ values of all the fish species were reported in the range from 0.001 to 0.410 and the coefficient of variation (r2) was noted in the range from 0.87-0.98. The data generated in the present study would be useful in determining the health status of these fish species as well as for their better management and conservation. | ||||
