Tab. 1 in Essential oils of Cunila galioides and Origanum majorana as anesthetics for Rhamdia quelen: efficacy and effects on ventilation and ionoregulation

Tab. 1. Effect of the essential oil of Cunila galioides (EOC) and Origanum majorana (EOO) on ventilatory rate in Rhamdia quelen. Statistics was performed through the Scherer-Ray-Hare extension of the Kruskal-Wallis test followed by the Nemenyi test; n=9; p <0.05. Results are expressed as the mean ± SEM. The fish exposed to 100 μL L- 1 EOC died within 2h of exposure. Lowercase letters indicate significant difference between times in the same group; capital letters indicate significant difference between groups at the same time.
