Length-weight relationship and relative condition factor of Lepidocephalichthys Guntea (Hamilton, 1822) of Ghati Beel of Dhemaji district of Assam, India

Abstract

The Length-weight relationship and relative condition factor of Lepidocephalichthys guntea (Hamilton, 1822) was studied for male, female and male & female combined (combined) of Ghati beel of Dhemaji District of Assam, India. The growth coefficient value ‘b’ in female is the highest (3.76) followed by combined (3.02) and the lowest in male (2.66). The negative allometric growth interestingly observed in male may be due to loss of energy during breeding behavior of the present study. The value of Correlation coefficient ‘r’ in male, female and combined was estimated at 0.92, 0.93 and 0.91 respectively. The value of relative condition factor (Kn) in male, female and combined varied from 0.78 –1.25, 0.75–1.21 and 0.76–1.34 respectively which show good general condition of the fish.
