Abstract
A sample of 109 specimens of Puntius ticto was examined from April 2020 to March 2021to find out length-weight relationships and relative condition factor. The total length of the fish sample ranged from 3.9 - 7.5cm. and weight 1.15-7.79gm. Correlation coefficient values for male (r=0.8583), female (r=0.8583) and pool data (r=0.8583) were noticed extremely significant. The relative condition factor was lowest during July i.e. 0.701±0.019 in males, 0.735± 0.029 in females, and 0.719± 0.023 in pool data. Its highest range 0.945±0.028 for males, 0.967±0.037 for the females, and 0.954±0.032 for pool data were observed in December. In the present work, negative allometric growth was observed in males (b= 1.7128), females (b= 1.8623) and pool data sexes (b= 1.7128) of Puntius ticto.
