The aim of this work was to evaluate the recovery of physiological stress responses after the transport of pacu juveniles in different stocking conditions. After being transported for 2 h30min, fish were transferred to earthen ponds or indoor polyethylene boxes. There was a significant reduction of cortisol values registered at fish arrival , 24 hours after, in both stocking conditions . The glucose concentration reduced significantly 72 hours after in fish stocked in earthen ponds , and 120 hours in fish stocked indoor. Osmolality, sodium, potassium and chloride behavior suggested the re-establishment of the homeostasis during the recovery period, mainly in fish kept in the earthen ponds. Concerning the hematological parameters, only hemoglobin concentration reduced significantly in the recovery period , without effect of stocking condition, which does not characterize feasible indicators. After transport, a management procedure that causes stress in fish, the recovery of the basal condition was fa vored when pacu were stocked in earthen ponds.
