The performance of pure and hybrid “pintado” Pseudoplatystoma hatchlings at feed training was evaluated. The intestinal coefficient (IC = length of the intestine/total fish lenght) was related to volume and mass and compared by means of analysis of multivariate variance and main components. According to the fish farming station routine, the training lasts about 60 days, when animals are conditioned to feeding on floating dried feed during daylight. Approximately one hundred animals per group were collected in the initial, intermediate […]
