Length-weight relationship and relative condition factor of Gudusia chapra (Hamilton, 1822) of Dalani Beel (wetland) of Assam, India

Abstract

The present study relates to the length-weight relationship of Gudusia chapra (Hamilton, 1822) of Dalani Beel of Assam. The finding shows that the correlation coefficient ‘r’ exhibits positive correlation between total length and body weight with coefficient correlation ‘r’ approaching towards +1, although the growth performance exhibits negative allometric correlation which may be due to lower feeding proficiencies and/or may be due to environmental and/or seasonal incompatibility for proper growth of fishes. In this investigation the value of ‘b’ in Gudusia chapra for adult and sub adult is 2.81 and 0.92 respectively. The Kn value for adult and sub adult ranged from 0.63 to 1.45 and 0.71 to 1.28 respectively, with an average value of 1.00 ± 0.10 for former and 0.99±0.14 for the later.
