Abstract: An attempt was made to study length-weight relationship and condition factor of exotic carp, Cyprinus carpio var. communis reared in bheries at Bhamanghata of South 24 Parganas district in West Bengal. Samples of 344 fishes having a size range of 87 mm to 245 mm were taken to estimate the length-weight relationship. The regression equation was found as logW=-4.570+3.062 logL(r=0.898) for male, logW=-4.645+3.143 logL (r=0.889)for femaleand logW= -4.627+3.097 logL (r=0.903) for pooled sample and it exhibited significant correlation between length and weight. It was found that the exponent ‘b’ value was not significantly deviating from ‘3’ indicating isometric growth. The mean relative condition factor (Kn) was found to vary from 0.93 to 1.19 during the period of investigation. It varied significantly (F11, 11=17.60, P<0.01) during different months which were attributed to food and feeding habit of fish.
