Abstract

The research on LWR (weight length relationship) of fish is key implement in fish biology examine and has received extensive courtesy. However, growth of fish is influence by many reasons and changed accordingly. Aim of this study was to investigate how fish body profile is affected by various factors by analyzing existing parameters of relationship between body length and weight. For studies on length weight relationship of major carp, Labeo rohita total 110 fish samples were analyzed. Samples were collected with the help of local fisherman. Size of male fish was ranging from 25.1-70.0 cm in length and 916g to 2395g in weight and size from 30.1-73.0 cm in length while in case of weight 803 to 2495 gram respectively.  It was observed from finding of current research work that Laboe rohita was found to be in optimum condition (b =2.0 and 1.9 and where r2 is 0.99 and 0.99) accordingly.  In case of relative condition factor (Kn) it was fluctuating between 1.2 and 1.4 respectively in both sexes.  Results of length weight relationship condition factor and also r2 value indicated that the values of length-weight and coefficient of condition analysis found to be in ideal condition.
