A comparison of length-weight relationship and relative condition factor among three groups of Leiodon cutcutia (Hamilton, 1822) of Diplai Beel (wetland) of Assam, India

Abstract

The present study reports the length-weight relationship, relative condition factor among adult male, adult female and sub adult group of of Leiodon cutcutia (Hamilton, 1822) of Diplai Beel (wetland) of Assam. The fishes were first separated into two groups-sub adult and adult stage (male and female). The growth performance of length-weight relationship has been found high since the correlation coefficient ‘r’ exhibits a high degree of relationship (0.94 in adult female and 0.93 in both sub adult and adult male) and shows all types growth pattern among different groups where positive allometric correlation (b=3.32) is observed in female adult, negative allometry (b=2.44) in sub adult and very interestingly isometric growth (b=3.00) in male adult. The Kn value for adult male and female of Leiodon cutcutia are 0.87 to 1.35 and 0.78 to 1.26 respectively, whereas in sub adult it is from 0.83 to 1.35.
