| The transportation of live fish is a routine procedure in aquaculture, and includes a series of stressful stimuli such as an increase in the stocking density of specimens per volume of water, and abrupt changes in water quality. This study evaluated the water quality and the stress levels on Pimelodus maculatus (Lacépède, 1803) fingerlings transported in plastic bags by a mechanical transportation simulator. Fish were stocked at densities 4 (22.88 g/L), 8 fish/L (45.76 g/L) and 12 fish/L (68.64 g/L) and the transportation simulation was performed for 4, 8 or 12 hours. A completely randomized experimental design applied to a 3 x 3 factorial model with three replicates was used. Water quality was evaluated by the analysis of the temperature, pH,... |
