| Abstract | |
This study unveils histological features of the intestinal tract of juvenile striped catfish Pseudoplatystoma fasciatum (Linnaeus, 1776) in three size classes (weight, standard length): I - 36.84 +/- 10.19 g, 14.52 +/- 1.54 cm; II - 59.03 +/- 11.47 g, 17.17 +/- 1.06 cm; III - 89.72 +/- 18.70 g, 20.79 +/- 1.55 cm, respectively. Histological organization of the juvenile speckled catfish intestine bears features common to the carnivorous fish, but the organ presents some convolutions that indicate a certain degree of dietary flexibility, a surprising trend, common only to omnivorous Siluriforms. The architecture of the mucosa of the speckled catfish intestine indicates that the species concentrates digestion and absorption of nutrients in the medium intestine, a common feature among carnivorous Teleosts.
