“…Considering that the concentration for sedation should be the minimum possible to avoid anaesthetic induction (Marking andMeyer 1985, Sena et al 2016), although the fact that the sedation time of the 10 μL L -1 concentration was superior to the other concentrations, 10 or 25 μL L -1 can be recommended for sedation for both essential oils. In addition, similar to our observations, the ratio of increased concentration versus reduction of anaesthesia time was verified in previous studies in Nile tilapia with eugenol (Ribeiro et al 2015) and essential oils of Lippia alba (Hohlenwerger et al 2016) and Aloysia triphylla (Teixeira et al 2017). On the other hand, the same studies verified that the anaesthetic recovery time increased with increasing anaesthetic concentration.…”

“…In general, according to the previous studies (Ribeiro et al 2015, Hohlenwerger et al 2016, Limma-Netto et al 2016, Teixeira et al 2017, the recovery time is affected by the increased anaesthetic concentration and is faster at lower concentrations, but this depends on the fish species and the anaesthetic used (as seen by Limma-Netto et al 2016. In the present study, we observe that the shortest time of exposure to the anaesthetic has been more determinant than the increase of the anaesthetic concentration to cause a faster recovery after anaesthesia.…”

This study aimed to verify the sedative and anaesthetic effect of the essential oils of basil (Ocimum basilicum) (EOOB) and lemongrass (Cymbopogum flexuosus) (EOCF) in Nile tilapia juveniles. The fish were transferred to aquaria containing different concentrations of each essential oil: 10, 25, 50, 100, 200, 400 and 600 μL L -1 . The time of sedation ranged from 7 to 31 seconds and the recommended concentration was 10 or 25 μL L -1 for both essential oils. The best times for anaesthesia and recovery were found for the concentrations of 400 μL L -1 for EOOB (135.2 and 199.1 seconds, respectively) and 600 μL L -1 for EOCF (327.1 and 374.8 seconds, respectively). In conclusion, we recommend the use of EOOB and EOCF for the sedation and anaesthesia of Nile tilapia at concentrations of 10-25 (for both), 400 and 600 μL L -1 , respectively.

“…This recovery time was similar to that observed in some fish species anesthetized with EOL-L (CUNHA et al, 2010;TONI et al, 2015;HOHLENWERGER et al, 2016) andA. triphylla EO (PARODI et al, 2014).…”

“…The lowest EOL-L concentration to induce anesthesia of H. geographicus tadpoles was 75µL L -1 and the lowest concentration to induce anesthesia within 5min was 100µL L -1 . These results demonstrated that this frog is relatively susceptible to anesthesia with EOL-L, since the lowest EOL-L concentration to induce anesthesia in fish is 50-200µL L -1 and to induce anesthesia within 5min is 50-450µL L -1 (CUNHA et al, 2010;TONI et al, 2015;HOHLENWERGER et al, 2016). The lowest EOAR concentration to induce anesthesia of H. geographicus tadpoles within 5min (200µL L -1 ) was somewhat higher than that of EO-L, but the lowest concentration to induce anesthesia was lower (25µL L -1 ).…”

The goal of this study was to investigate the sedative and anesthetic properties of essential oils (EOs) in map treefrog tadpoles (Hypsiboas geographicus) and to determine the sedation and deep anesthesia induction times as well as the recovery time. The tadpoles were exposed to one of the EOs from three plant species: Aniba rosaeodora (EOAR - 25, 50, 100 or 200µL L-1), Lippia origanoides (EOLO - 13, 25, 50, 100 or 200µL L-1), and Lippia alba (either chemotype citral [EOL-C - 25, 50, 100 or 200µL L-1] or linalool [EOL-L - 50, 75, 100 or 200µL L-1]) (n = 8 per replicate). The tadpoles exposed to 25 and 50µL L-1 EOL-C and EOL-L, respectively, were not anesthetized within 30min (the maximum time of observation), and those exposed to 200µL L-1 EOLO did not recover within 30min. Sedation, deep anesthesia and recovery times showed a concentration-dependent relationship for all EOs tested, with the exception of the recovery with EOLO. The results allowed concluding that all investigated EOs can be used to anesthetize tadpoles of H. geographicus, but the use of EOLO must not exceed 100µL L-1.

“…The EO of Lippia alba has been highlighted in the last decade through studies reporting its potential as antioxidant, anesthetic and sedative for fish (Cunha et al, 2010;Becker et al, 2012;Heldwein et al, 2014;Toni et al, 2014;Hohlenwerger et al, 2016).…”

The aim of this study was to evaluate if Lippia alba has different chemotypes according to the chemical composition of the essential oil (EO) considering collection site, and if the EO may have different effects on blood and plasma parameters in silver catfish, Rhamdia quelen, during and immediately after anesthesia. The citral (EO-C) and linalool (EO-L) chemotypes were identified, and both presented similar anesthetic effects for silver catfish. Fish were exposed to two concentrations of each EO, which induced slow and fast anesthesia (100 and 300 µL L -1 , respectively). Blood ions did not change at any time of anesthesia induction and recovery and, therefore, the electrolyte balance was not altered. Blood gases oscillated through all exposure and recovery times, but there was an increase in pO 2 after 10 min recovery in fish anesthetized with EO-C. Glucose increased in fish exposed to both EOs when compared with the control group. Overall, exposure to both EOs (except 100 µL L -1 EO-L at most times) reduced plasma cortisol levels compared to the control and/or ethanol groups. However, as plasma creatinine levels in fish anesthetized with EO-C were higher than control fish, the use of EO-L is preferable.Keywords: Blood gas, Cortisol, Glucose, Plasma ions, Silver Catfish.O objetivo deste estudo foi avaliar se Lippia alba apresenta diferentes quimiotipos de acordo com a composição química do óleo essencial (OE), considerando local de coleta e se o OE causa diferentes efeitos nos parâmetros sanguíneos e plasmáticos em jundiá, Rhamdia quelen, durante e imediatamente após a anestesia. Os quimiotipos citral (OE-C) e linalol (OE-L) foram identificados e ambos apresentaram efeito anestésico semelhante para jundiá. Os peixes foram expostos a duas concentrações de cada OE, que induziram anestesia lenta e rápida (100 e 300 mL L -1 , respectivamente). Íons sanguíneos não se alteraram em nenhum tempo e consequentemente, o equilíbrio eletrolítico não foi alterado. Os gases sanguíneos oscilaram durante todo tempo de exposição e recuperação, mas houve aumento na pO 2 após 10 min de recuperação em peixes anestesiados com OE-C. Níveis sanguíneos de glicose aumentaram nos peixes expostos a ambos OEs quando comparados com o grupo controle. De um modo geral, a exposição a ambos OEs (exceto 100 µL L -1 OE-L na maioria dos tempos) reduziu o cortisol plasmático comparado aos grupos controle e etanol. No entanto, como os níveis de creatinina plasmática em peixes anestesiados com OE-C foram maiores que nos peixes controle, é preferível o uso do OE-L.
