Fig. 1 in Anesthesia and transport of fat snook Centropomus parallelus with the essential oil of Nectandra megapotamica (Spreng.) Mez
Fig. 1. Mortality after transport of fat snook Centropomus parallelus in plastic bags with essential oil from old leaves of Nectandra megapotamica (15 or 30 µL L-1) or ethanol (E) added to the water. W: control with only water. Data presented as means ± SEM (n = 3). a, freshwater - no significant difference between groups or times was observed and the treatments E and 15µL L-1 are superimposed on the first line; b, seawater - values with different superscripts are significantly different (P <0.05). # Significant difference from arrival (0 h).

FIGURE 5 | Antioxidant and oxidative stress parameters in the liver after transferring to recovery aquariums of fat snook (Centropomus parallelus) anesthetized with the essential oil from Lippia alba (EOLA). A = GST (glutathione S-transferase). B = SOD (superoxide dismutase). C = CAT (catalase). D = LPO (lipid peroxidation). Data are presented as the mean ± SEM (n = 5 fish per treatment each time). Capital letters indicate significant differences between time points within the same treatment. Lowercase letters indicate significant differences between treatments at the same time point. Two-way ANOVA and Tukey's tests were used to determine statistical significance (P <0.05).
