Blood glucose (Glu) and c-d. plasma cortisol in silver catfish (Rhamdia quelen) (n = 6) subjected to different concentrations of essential oils from the linalool (EO-L) and citral (EO-C) chemotypes of Lippia alba. Values are mean ± SEM. Different letters indicate significant differences between times within the same treatment. * indicates significant difference from control, # indicates significant difference from ethanol.
