Length-Weight relationship and relative condition factor of Puntius sophore (Hamilton, 1822) and Systomus sarana (Hamilton, 1822) of Deepar Beel (wetland) of Assam, India

Abstract

The present study reports the length-weight relationship, relative condition factor of two fish species Puntius sophore (Hamilton, 1822) and Systomus sarana (Hamilton, 1822) of Deepar Beel (wetland) of Assam. The fishes are separated into two groups-Sub Adult and adult stage. The growth performance of length-weight relationship is found high since the correlation coefficient ‘r’ exhibits high degree of relationship but shows negative allometric correlation. The negative allometric growth may be due to lower feeding proficiencies and/or may be due to environmental or seasonal incompatibility for proper growth of fishes. 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 Kn value of Sub Adult Puntius sophore, Adult Puntius sophore, sub adult Systomus sarana and adult Systomus sarana are 0.93 - 1.07, 0.85 - 1.19, 0.90-1.13 and 0.86 -1.06 respectively which are more or less similar.
