ABSTRACT
The length-weight relationship and condition factor of Labeo rohita and Labeo fimbriatus were analyzed to evaluate the significance of allometric growth and the overall well-being of the species. The study was conducted for a period of six months. A total of 160 individuals were examined. For L. rohita, total lengths ranged from 13.2 cm to 46.0 cm, with weights between 193.65 g and 1490.05 g. In the case of L. fimbriatus, lengths varied from 11.0 cm to 43.8 cm, and weights ranged from 186.3 g to 1216.3 g. The slope value (b) estimated for L. rohita and L. fimbriatus were 2.73 and 2.81, which shows both the species exhibits negative allometric growth pattern. The regression equation calculated for L. rohita was Log W = -1.216 + 2.73 Log L and for L. fimbriatus was Log W = 0.032 + 2.81 Log L. The b value differed from the ideal cube law of ‘3’ as is the case of the length-weight relationship studied in this species else-where. The mean values of computed condition factor for all specimen of L. rohita were 1.76 and L. fimbriatus was 1.95 which indicated that both the species are generally in good condition within their habitat.
