ABSTRACT: Anesthetics are effective to reduce or minimize stress in handling operations related to fish cultures. Aiming to avoid residual effects of synthetic drugs, several natural agents, such as essential oils (EOs), have been tested. The aim of this study was to determine the optimal concentration of the EO of Ocimum micranthum for induction of anesthesia in juveniles of silver catfish (Rhamdia quelen) and grass carp (Ctenopharyngodon idella). Results demonstrated that the most suitable concentration to sedate silver catfish and carp is 25μL/L, while to anesthetize 200μL/L is more suitable for silver catfish and 100μL/L for grass carp, because these concentrations induce deep anesthesia in less than three min and recovery in less than five min. Analysis of the EO constituents showed methyl chavicol, a compound with carcinogenic potential, as the major component (58.2%). Therefore, the EO of O. micranthum is not recommended for fish anesthesia if the fish are to be used as food.
