| Abstract | ||||
| The bivariate size allometry of Chrysichthys auratus was estimated by the application of the power function equation of HUXLEY (1932) on certain - morphometric characters in terms of its parameters. The bivariate allometric concept was expanded for multivariate data by JOLICOEUR'S (1963) approach and the presence of multivariate allometry was revealed by ANDERSON'S (1963) test. Also, the allometric nature in the morphomet ric indices of the species studied was determined and discussed. According to the patterns of bivariate and multivariate allometry exhibited, sexual dimorphism and racial differences in Chrysichthys auratus were evident. | ||||
