This study aimed to examine the action of the essential oil of Lippia alba (EOLA) in the stress response for transport of Nile tilapia Oreochromis niloticus. The fish were transported into three treatments (in triplicate): control, 10 and 20 μL L-1 EOLA, with loading density of 15 fish/plastic bags for 8h. Plasma glucose levels were significantly decreased in fish exposed to 20μL L-1 EOLA in comparison with the control group and fish exposed to 10μL L-1 EOLA, but the plasma cortisol, lactate and paraoxonase levels were similar. Un-ionized ammonia and ventilatory rate demonstrated a significant reduction in the treatments with the use of EOLA. In conclusion the use of 20μL L-1 EOLA is indicated for Nile tilapia transport.
