Five meristic counts and 21 morphometric measurements were studied and compared between males and females Schilbe mystus. Statistical analysis showed no significant differences in the number of meristic counts. Students t-test showed that the mean of the 21 morphometric measured traits was significantly (p<0.001) higher in females than males. The regression analysis of the various morphometric measurements of S. mystus against the standard length yielded significantly correlated equations (p<0.05 to p<0.001) with females showing higher degree of correlation (r value) than males, except for the preorbital length and prepelvic length.
