Abstract: The objective of this study was to observe the determine length weight relationship and condition factor of Cirrhinus mrigala (Ham.) fish in Barnoo reservoir, Jabalpur (M.P.) for two years study. The present study indicates that the fish did not follow the cube law (W= a Ln) because the value of ‘n’ in a shade lower than three, and is deviated from cube law. The parabolic equation for the statistical relationship between the length and weight was recorded; W= 0.011542 L 1.480565 and W= 0.000266 L 1.68807. The condition factors (K) were also estimated for to determine the wellbeing of fishes and was found satisfactory growth of Mrigala fish at Barnoo reservoir. The values of condition factor (K) of Cirrhinus mrigala was also computed and found that the species performed well. The maximum of ‘K’ value was found 1.6103 in the month of December. Observed condition factor of Cirrhinus mrigala reported that the fish were in well condition during the study period.
