The length-weight relationship of a fish Barilius barila (Gunther) was studied which was collected from Wainganga river located 20’48º N 79’38º E. The entire length-weight data were analyzed by least square method. The length- weight relationship of Barilius barila was studied in 258 fishes under three categories as male, female and common. Their corresponding parabolic representations are male B. barila W = 0.008167 L 2.8829 , female B. barila W = 0.005931 L 3.1223 and common B. barila W = 0.006415 L 3.0373 . The equilibrium constant ‘b’ is found to be 2.8829 in males, 3.1223 in females and 3.0373 common. The females are heavier than males at equal length. The equilibrium constant does not obey the cube law because it deviates from 3. The value of common fish was found to be more than 3 indicates the environment of Wainganga river was good for healthy development of fishes.
