TABLE 4 in Anesthetic potential of essential oils from Brazilian native plants in Rhamdia quelen juveniles (silver catfish)

TABLE 4 | Anesthetic induction and recovery times (s) in Rhamdia quelen juveniles exposed to essential oils of Acmella oleracea inflorescences (AOOi) and leaves (AOOl), Aloysia hatschbachii leaves (AHOl), and Cordia verbenacea leaves (CVOl). Mean ± standard deviation of the mean. Different letters in the same row indicate a significant difference between concentrations (n = 8); (-) indicates stage not reached; (-*): indicates no recovery in the maximum observation time (30 min).
