Abstract: The length-weight relationship, condition factor and relative condition factor of combined sexes Kalibaus fish Labeo calbasu (Hamilton, 1822) of Kaptai Lake, Rangamati, Bangladesh were studied during August 2017 to December 2017. Length-weight(s) of 284 specimens of Kalibaus fish were collected for five consecutive months. The relation between total length and total weight of Kalibaus fishes of three groups were estimated as ln W1 = - 4.189 + 2.97.ln L1, ln W2 = - 4.166 + 2.95.ln L2, and ln W3 = - 4.082 + 2.93.ln L3 for sexes combined. The analysis of correlation coefficient (r = 0.9897, 0.9914 & 0.9844) indicated that there were highly significant (p˂ 0.01) relationship between the length and the weight of fish of all three groups. The respective mean condition factors 1.396, 1.310 & 1.367 showed that Kalibaus fish was in a better environmental condition, but the respective growth coefficients 2.97, 2.95 & 2.93 and the respective mean relative condition factors 1.02, 1.00 & 1.03 showed that Kalibaus fish was in a good aquatic environment in Kaptai Lake. The growth patterns of fishes of all groups seemed to be isometric. The overall results showed that Kaptai Lake could be a good freshwater reservoir for growing up of L. calbasu.
