Studies on length-weight relationship and condition factor of Hilsa ilisha from Chilika Lake, Odisha


Author(s): Nibedita Mohanty and Lakshman Nayak

Abstract: The present study describes the length-weight relationship and relative condition factor of Hilsa ilisha based on the length and weight data collected from Chilika Lake during January, 2014 to December, 2014. The specimens were collected using the gill net from the Chilika Lake. The work was carried out on 497 fishes ranging from 17.5 to 50.2 cm in length and weight of fishes ranging from 120 to 1370gm.The value of correlation coefficient was calculated to be 0.9684 indicating a high degree of correlation between the length and the weight. The parabolic and regression equations were found to be W = 0.0174L2.99 and Log W= −1.75945 + 2.99 log L, respectively. The exponent value 2.99 nearly confirms to the cube law, 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.
