Fig. 1. Schematic representation of the experimental design of both groups of experiments. In experiment "A," Rhamdia quelen (Quoy & Gaimard) fingerlings were sequentially exposed to the same stressors twice and to a different stress the third time. In experiment "B," R. quelen fingerlings were sequentially exposed as the same stressors 3 times.
