Length-Weight relationship and relative condition factor of Rita rita (Hamilton, 1822), Pangasius pangasius (Hamilton, 1822)and Chitala chitala (Hamilton, 1822)of Brahmaputra river system of Assam, India

Abstract: The present study reports the length-weight relationship, relative condition factor of three important fish species Rita rita (Hamilton, 1822), Pangasius pangasius (Hamilton, 1822)and Chitala chitala (Hamilton, 1822)of Brahmaputra river system. The growth performance of all the 3 fishes are found high since the correlation coefficient ‘r’ exhibits high degree of relationship where Pangasius pangasius and Chitala chitala shows positive allometric correlation and Rita rita negative allometric correlation. The present study also indicates that the value of ‘b’ in all fishes deviate from ‘cube law’ as it remains constant at 3.0 for an ideal fish. The Kn value Rita rita, Pangasius pangasius and Chitala chitala are 0.78 - 1.55, 0.85 - 1.30 and 0.79 -1.24 respectively.
