Abstract: The present study reports the length-weight relationship, relative condition factor of two fish species Parambassis ranga (Hamilton, 1822) and Chanda nama (Hamilton, 1822) commonly known as Chanda in Assamese of Dora beel (wetland) of Assam. The growth performance of length-weight relationship is found moderate since the correlation coefficient ‘r’ reveals moderate degree of relationship and also shows negative allometric growth. The negative allometric growth may be due to poorer feeding ability; environmental inappropriateness including physicochemical parameters; seasonal incompatibility including breeding seasons for proper growth of fishes etc. The present findings also indicate that the value of ‘b’ in all cases is lower than 3.0, being a constant for an ideal fish. The range of Kn value of Parambassis ranga and Chanda nama are 0.49-2.28 and 0.60-1.52 respectively. In both the cases the Kn value decreases from lighter to heavier fish first to attain minimum in medium sized fish samples and increase steadily to attain maximum near to the heavier fish.
