| Popis: | The development of the digestive system and digestive proteases was studied in cachara (Pseudoplatystoma reticulatum) and its hybrid (P. reticulatum × Pseudoplatystoma corruscans) during the first 25 days after fertilization. Both groups presented a fast and similar development of the digestive system, and the unspecific alkaline protease profile suggested that the digestive capacity of hybrid larvae is higher than that of cachara after the last half of the studied phase. The activities of trypsin and chymotrypsin were similar and observed since the oocyte. These observations suggested that cachara and its hybrid has similar digestive capacity and digestive system development. |
