“…Nonetheless, the induction times of different stages of anesthesia were similar for all of the salinities at a menthol concentration of 50 mg L -1 . These results are contrary to findings described by Ghazilou et al (2010), who reported that during the clove oil-induced anesthesia of Caspian salmon (Salmo trutta caspius), the induction times increased at higher water salinities, suggesting that the increased times were attributed to the "salting out" phenomenon. As an estuarine fish, the fat snook is well adapted to salinity changes.…”

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.

“…In this study, we compared the anesthetic activity of EO of N. megapotamica at different salinities through the times of induction and recovery of anesthesia and, in general terms, there was a shorter induction and recovery times in FW-adapted fat snook. Ghazilou et al (2010) observed that Caspian salmon [Salmo trutta caspius (= Salmo caspius)] exposed to clove oil at different salinity levels showed an increase in the induction time with increasing salinity. According to Ross & Ross (2008), due to the buffering capacity of SW and its ionic constituents, the effects of some drugs may be modified in SW.…”

This study analyzed the chemical composition and anesthetic potential of essential oil (EO) of Nectandra megapotamica in fat snook (Centropomus parallelus). For the extraction of EO by hydrodistillation, leaves were separated in young (EO-Y) or old (EO-O), and the chemical composition of the EOs was determined by CG-MS. The anesthetic potential was assessed by the evaluation of induction and recovery time of anesthesia and stress response from anesthesia and transport. Three experiments were carried out: i) four different concentrations of each EO were tested to evaluate anesthesia induction and recovery time; ii) two concentrations of EO-O were tested for the evaluation of its effects on stress parameters (glucose, lactate, and Na + and K + plasma levels) caused by anesthesia; and iii) fish were transported in plastic bags, supplied with two concentrations of EO-O for the evaluation of water quality and mortality. All experiments were performed on fish acclimated to 0 and 33 ppt salinity. The main constituents of the Y and O-EOs were bicyclogermacrene (46.5/34.6%), α-pinene (26.8/26.2%), β-pinene (7.9/12.3%), and germacrene D (9.6/9.1%). Mild sedation was achieved at 30 µL L -1 (1.3-3.2 min) and deep anesthesia at 150 µL L -1 (5.6-8.0 min) with both EOs. The recovery time ranged from 1-10 min. The EO-O was not able to avoid the stress of anesthesia evidenced by elevated glucose and lactate plasma levels observed in all groups. Plasma levels of Na + and K + were not significantly affected by treatments. During transport, the use of EO-O did not prevent deterioration in water quality and the post-transport mortality. In conclusion, the EO of N. megapotamica has anesthetic activity in fat snook, but it was not able to prevent the stress of anesthesia and transport.Este estudo analisou a composição química e o potencial anestésico do óleo essencial (OE) de Nectandra megapotamica em robalos-peva (Centropomus parallelus). Para a extração do OE por hidrodestilação, as folhas foram separadas em jovens (OE-J) ou velhas (OE-V) e a composição química foi determinada por CG-EM. O potencial anestésico foi acessado através da avaliação do tempo de indução e recuperação da anestesia e resposta ao estresse do procedimento anestésico e transporte. Foram realizados três experimentos: em primeiro lugar, quatro concentrações diferentes de cada OE foram testadas para avaliar o tempo de indução à anestesia e de recuperação; em segundo lugar, duas concentrações do OE-V foram testadas para avaliar os efeitos sobre os parâmetros de estresse (níveis plasmáticos de glicose, lactato, Na + e K + ) causados pelo procedimento anestésico; em terceiro lugar, os peixes foram transportados em sacos plásticos com duas concentrações do OE-V para avaliação da qualidade da água e mortalidade. Todos os experimentos foram realizados em peixes aclimatados à salinidade zero e 33. Os constituintes majoritários do OE-J e OE-V foram: biciclogermacreno (46,5/34,6%), α-pineno (26,8/26,2%), β-pineno (7,9/12,3%) e germacreno D (9,6/9,1%). Sedação leve foi alca...

“…Water temperature and salinity have been used to anaesthetize fish under various conditions, demonstrating anesthetic influence in themselves. Similar studies of changes in water temperature (20℃, 24℃, and 28℃), salinity (10, 20, and 30 ppt), and anaesthesia and anaesthesia concentrations (15, 30, 45, and 60 ppm) were carried out in kelp grouper, Epinephelus bruneus , steelhead, Oncorhynchus mykiss , rock bream, Oplegnathus fasciatus , Caspian salmon, Salmo trutta caspius , and marine medaka, Oryzias dancena (Woolsey et al, 2004; Park et al, 2008b, 2009, 2011; Ghazilou et al, 2010). At each temperature and concentration in the anaesthesia experiment, exposure time decreased with increasing temperature and concentration and recovery time decreased with increasing temperature and concentration (Woolsey et al, 2004; Park et al, 2008b, 2009b, 2011).…”

“…Considering salinities and anaesthesia concentrations, puffer fish met the anaesthesia condition within 3 mins and recovered within 5 mins at each salinity and concentration. Ghazilou et al (2010) studied the relation of different salinities and concentrations on exposure times and recovery times. In this study, river puffer and tiger puffer were shown to be more sensitive to clove oil, water temperature and salinity.…”

The effects of the anaesthetic agents, clove oil and mixture of clove oil with lidocaine-HCl were evaluated on river puffer, Takifugu obscurus and tiger puffer, T. rubripes . Anaesthesia times of clove oil were affected by water temperature (20℃, 24℃, and 28℃) and salinity (10, 20, and 30 ppt). Anaesthesia times of mixed samples were significantly similar with regard to exposure and recovery times, and all samples satisfied anaesthesia criteria (exposure time within 3 min and recovery time within 5 min) under the various temperatures and salinities, and the lowest to highest concentration of anaesthetics ( p <0.05). Both species river puffer and tiger puffer had short exposure time with a high anaesthesia dose, high temperature (28℃) and intermediate salinity (20 ppt), and were highly affected by temperature and salinity ( p <0.05). The mixed anaesthetics had rapid exposure times and long recovery times in contrast to the effects of clove oil. Cortisol concentrations under the conditions of various clove oil dosages, salinity, and temperature for both species increased until 12 hrs after recovery from anaesthesia ( p <0.05). After 12 hrs, cortisol concentrations decreased until after 48 hrs ( p <0.05). During the simulated transportation of both species, control and sedated clove oil groups (5 ppm) were measured for water parameters, dissolved oxygen (DO), CO 2 , respiratory frequency, NH 4 + , and pH for 6 hrs in 1 hr intervals. Water parameters of sedated groups and controls were significantly different after 2 hrs ( p <0.05).
