The Length Weight Relationship of a Riverine Fish Chela bacaila ( Gunther )

Abstract

The length-weight relationship of a fish Chela bacaila (Gunther) was studied which was collected from Wainganga river. The entire length-weight data were analyzed by least squire method. The length-weight relationship of Chela bacaila was studied in 386 fishes under three categories as male, female and common. Their corresponding parabolic representations are male C. bacaila W = 0.006634 L^2.9086 , female C. bacaila W = 0.012325 L ^2.6478 and common C. bacaila W = 0.013283 L ^2.8097. The equilibrium constant is found to be 2.9086 in males, 2.6478 in females and 2.8097 common. The males are heavier than females at equal length. The equilibrium constant not obeys the cube law because it deviates from 3. The value of b found to be less than three hence it indicates the river condition was not found good for healthy development of Chela bacaila .
