“…Hormone storage was suggested in studies with rainbow trout (Oncorhynchus mykiss), because it releases cortisol and adrenaline immediately after netting procedures and 30 s of air exposure (Gerwick et al, 1999). Furthermore, a hyperactivity period at the beginning of clove oil exposure, which also contains eugenol as the major compound, was described on Nile tilapia (Oreochromis niloticus) (Simões et al, 2011). As this pattern was also verified for the EOO tested (data not shown), pre-synthesized hormones could have been released during this time before the fish reached deep anesthesia, and may have produced the effects observed.…”

ABSTRACT:The effects of anesthesia with the essential oil of Ocimum gratissimum (EOO) in parameters of stress after handling were investigated in silver catfish (Rhamdia quelen). EOO was obtained from the aerial parts by hydrodistillation. Juveniles were anesthetized with 70 or 300 mg L -1 EOO and submitted to air exposure for 1 minute. The fishes were sampled immediately or transferred to anesthetic-free aquaria until sampling. In the first experiment, juveniles had their blood collected at 0, 1, 4, and 8 h after handling to assay plasma cortisol and blood glucose levels. The unanesthetized animals were restrained manually for blood collection. In the second experiment, water samples of the recovery aquaria were collected to evaluate net ion fluxes at 0 -4 h and 4 -8 h. Water and ethanol controls were also performed under the same conditions. The results showed that the cortisol levels did not differ among the treatments. Hyperglycemia was verified in fish exposed to 70 and 300 mg L -1 EOO at 1 h and 4 h after handling. After 8 h, cortisol and glucose concentrations were lower or similar than those from immediately after handling for all treatments. EOO anesthesia prevented Na + efflux observed in the control groups in both flux periods. There were net Cl -and K + effluxes at 0 -4 h and influxes at 4 -8 h after handling in most treatments, and these fluxes did not differ among the treatments. The results suggest that EOO did not impair stress recovery and did not act as an additional handling stressor in silver catfish.Key words: clove basil, cortisol, glucose, net ion flux, silver catfish. RESUMO: Efeitos da anestesia com o óleo essencial de Ocimum gratissimum L. em parâmetros de estresse de peixes. Os efeitos da anestesia com o óleo essencial deOcimum gratissimum (EOO) em parâmetros de estresse após manuseio foram investigados em jundiás (Rhamdia quelen). EOO foi obtido a partir das partes aéreas por hidrodestilação. Os juvenis foram anestesiados com 70 ou 300 mg L -1 de EOO e expostos ao ar por 1 minuto. Os peixes foram amostrados imediatamente ou transferidos para aquários sem anestésico até amostragem. No primeiro experimento, os juvenis tiveram seu sangue coletado em 0, 1, 4, e 8 h após manuseio para avaliar os níveis de cortisol e glicemia. Os animais não anestesiados foram contidos manualmente para coleta sanguínea. No segundo experimento, amostras de água foram coletadas do aquário de recuperação dos animais para avaliação do fluxo iônico entre 0 -4 h e 4 -8 h. Grupos controles em água e etanol também foram realizados sobre as mesmas condições. Os resultados demonstraram que os níveis de cortisol não diferiram entre os tratamentos. Hiperglicemia foi detectada em peixes expostos a 70 e 300 mg L -1 de EOO em 1 h e 4 h após o manuseio. Após 8 h, os teores de cortisol e glicose foram menores ou similares aqueles imediatamente após o manuseio para todos os tratamentos. A anestesia com EOO preveniu o efluxo de Na + observado para os grupos controle em ambos os períodos avaliados. Ocorreram efluxos de Cl-and ...

“…In this context, menthol has been used as an anesthetic for marine invertebrates and fish (Ross and Ross, 1999;Simões and Gomes, 2009). Similar to other natural oil-derived anesthetics (Small, 2003;Simões et al, 2011;Souza et al, 2012), menthol has several features and qualities that make it suitable for use as a fish anesthetic (Façanha and Gomes, 2005).…”

The effectiveness of menthol as anesthetic and sedative for fat snook (Centropomus parallelus) was tested at different salinities. In the first experiment, the fish were exposed to different concentrations of menthol (25, 37 and 50 mg L -1 ) in water at different salinities (0, 17 and 36 ppt). In the second experiment, the fish were transported for 10 hours in water with menthol at concentrations of 0, 3.7 and 7.4 mg L -1 under different salinities. Na + and K + ions from fish body and water were analyzed after transport. The optimal concentrations of menthol for a short handling period and surgical induction was 37 and 50 mg L -1 , respectively, and these values were independent of salinity. After transport, neither mortality nor significant changes in ammonia or dissolved oxygen were observed between treatments at the different salinities. The nitrite levels were lower in freshwater than in brackish and saltwater, but did not change with mentol. The total body levels of Na + increased with the salinity increase. Menthol is an effective anesthetic for handling of juvenile fat snook at different salinities. Menthol did not influence the measured water parameters and body ions, and it is not necessary for the transport of fat snook.Keywords: anesthesia, stress, fish, body ions, sedation.Salinidade não altera a eficácia de mentol como um anestésico e sedativo durante a manipulação e transporte de juvenis de robalo peva (Centropomus parallelus) ResumoA eficácia de mentol como anestésico e sedativo para o robalo peva (Centropomus parallelus) foi testada em diferentes salinidades. No primeiro experimento, os peixes foram expostos a diferentes concentrações de mentol (25, 37 e 50 mg L -1 ) em diferentes salinidades na água (0, 17 e 36 ppt). No segundo experimento, os peixes foram transportados por 10 horas em água com mentol nas concentrações de 0, 3,7 e 7,4 mg L -1 sob diferentes salinidades. O Na + e K + do corpo do peixe e a água foram analisados após o transporte. As concentrações ideais de mentol para um período curto de manipulação e indução cirúrgica foi 37 e 50 mg/L, respectivamente, sendo esses valores independentes da salinidade da água. Após o transporte, não foi verificado mortalidades e nem alterações significativas nos níveis da amônia e oxigênio dissolvido entre os tratamentos para as diferentes salinidades. Os níveis de nitrito foram mais baixos em água doce do que em água salobra e água salgada, mas não se alterou com o mentol. Os níveis corporais de Na + e K + aumentaram com o aumento da salinidade. Mentol é um eficaz anestésico para manipulação de robalo peva juvenil em diferentes salinidades. Mentol não influenciou os parâmetros de medição de água e íons do corpo, e não é necessário para o transporte de robalo peva.
