Abstract
The present study describes the length–weight relationship and condition factor in Channa punctatus (Bloch) from Hussainsagar lake, Hyderabad A.P. The work was carried out on 200 fishes ranging from 15 to 30 cm in length. The value of correlation coefficient was calculated to be 0.991 indicating a high degree of correlation between the length and the weight. The parabolic and regression equations were found to be w = 0.03273 L 2.621 and log W = −1.485 + 2.621 log L, respectively. Deviation in the cube law was observed, and the condition factor showed continuous decrease with increase in length indicating a physiological response of the fishes to different environmental conditions of the lake waters.
