Length-weight relationships and condition factor of Salmo trutta fario (Brown trout) at Kokernag trout fish farm, Anantnag, Jammu and Kashmir was estimated for a period of one year. During the present study the fish samples was within the range of 30cm to 45.8cm in length and 250g to 750g in weight were originally used to provide information on the condition of fish and to determine whether somatic growth was isometric or allometric. The relationship was analysed using the formula W = a Lb which was further transformed into Log W = a + b log L. The equation obtained for females was log W= 1.61 + 3.33 logL and for males was log W = 1.81 + 3.22 logL. Females show 'b' value slight more than males. Studies on condition factor revealed that the fluctuations in K values can be attributed to the spawning cycle. The condition factor 'K' was above 1 indicating robustness or well being of the experimental fish.
