Abstract: The present study reveals the length-weight relationship of Channa gachua (Hamilton, 1822) of Garjan Beel of Assam. The present finding indicates that the correlation coefficient ‘r’ exhibits strong positive correlation between total length and body weight, with coefficient correlation ‘r’ approaching almost towards +1, although the growth performances 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 Channa gachua is 2.76 and the Kn value ranged from 0.52-1.94 with an average of 0.71 ± 0.17.
