Abstract: The present study attempts to develop a comprehensive Length-Weight relationship and relative condition Factor (Kn) of Channa punctata collected from River Manu in Tripura. The value of exponent ‘n’ in the equation W = cLn was found to be 2.818 for the species Channa punctata. The computed ‘t’ value indicated that the ‘n’ value of the species is not significantly different from the expected value ‘3‘and hence the Cube Law W = cLn hold good in the case of Channa punctata. The computed co-relation co-efficient (r) in Channa punctata was found to be 1 indicating that there is high positive correlation between length and weight in the species. The relative Condition Factor (Kn) remained greater (1.01) than 1 for the species indicating their general well being to be good in Manu river in Tripura.
