Abstract

A Length Weight Relationship (LWR) and condition factor of cultured rainbow trout Oncorhynchus mykiss was studied. A total of 144 specimens were used obtained from National fish farm Laribal, Dachigam during January 2017 to December 2018. The coefficient ‘b’ value of LWR showed negative allometric (b<3) growth throughout the year except in the months of October and December, where the positive allometric growth pattern was reported (b>3). In order to generate more precise information, a trend line graph was draw to compare condition of fish in different months, which indicated declining growth pattern condition. The condition factor showed an overt variation with highest value was reported during the breeding season. The result obtained in this study will be useful for the improvement of production and quality of trout under cultured condition.
