Abstract: Length-weight relationship of Labeo calbasu and Labeo fimbriatus, was studied a period of one year from June 2017 to May 2018. The slope value (b) estimated for L. calbasu and L. fimbriatus both male were found to be 2.1655 and 2.8185, which shows both the species exhibits negative allometric growth pattern. The regression equation calculated for L.calbasu was Log W = -1.0004 + 2.1655 Log L and for the L. fimbriatus was found to be Log W = -1.40391 + 2.8185 Log L. Both the species were length-weight relationships analysed by Analysis of Variance (ANOVA).The result was found lower stretches of Tamiraparani river with three sampling sites respectively. The F value between the species showed a significant difference at 1% level. The b value differed from the ideal cube law of ‘3’ as is with the case of length-weight relationship studied in this species else-where. L. fimbriatus and L. calbasu had a ‘b’ value of 2.8185 and 2.1655. The slope value was compared here could be very useful for comparison with Labeo species in other geographical locations.
