Abstract: The present study reveals about the length-weight relationship of Mystus tengara (Hamilton, 1822) of Lechia-Pavomari beel of Dhemaji District of Assam. The district is situated between longitude 94°12ʹ18ʺ & 95°14ʹ32ʺ E and latitude 27°05ʹ27ʺ & 27°57ʹ16ʺ N. In the present evaluation it is found that the correlation coefficient ‘r’ indicates strong positive correlation between the total length and the body weight, with coefficient correlation ‘r’ approaching almost towards 1. The relative condition factor of Mystus tengara is observed to increase from lighter to heavier fish. The negative allometric pattern of growth may be due to unsuitable feeding proficiencies and/or may be environmental and/or seasonal incompatibility for proper growth of fishes. In this investigation, it is found that the value of ‘b’ of Mystus tengara is 2.07 and the Kn value ranges from 0.74-1.39 with an average of 1.00±0.125.
