%X principal component analysis were performed on samples of two hybrids catfish, yaque pintado (pseudoplatystoma fasciatum£¿ x leiarius marmoratus) and chorrosco (pseudoplatystoma fasciatum x pimelodus blochi) for determining morphological differences and similarities. the truss network proposed by£¿ strauss and bookstein (1982) was used to obtain 20 morphometric distance measurements for determining multivariate allometric coefficients (mac) using£¿ principal component analysis.£¿ jackknife resampling was used to evaluate differences between the allometric coefficients of the hybrids. 9 of£¿ these measurements were statistically different (p < 0.05) and the rest do not showed significant differences£¿ (p >0.05). the methods and analysis used show each of the£¿ hybrids (yaque pintado and£¿ chorrosco) has similar growth trajectories.
