“…Regression curves obtained for all assays in the present study had a pattern similar to those established by other authors for eugenol (Vidal et al, 2007;Bernardes Júnior et al, 2013;Ribeiro et al, 2013) and for tricaine (Pawar et al, 2010), indicating a marked decrease in induction time between lower concentrations and a tendency toward stability as doses increase. Furthermore, the standard deviation was inversely proportional to the doses tested, of which the lowest values of standard deviation were shown with the highest dosages.…”

“…The same study suggested that 98 mg L -1 of eugenol induces anesthesia in 1 minute based on the calculated regression model. Other regression models estimated that a concentration of 24 mg L -1 of eugenol is sufficient to induce anesthesia for pacamã (Lophiosilurus alexandri) juveniles (7.44 ± 0.44 g) at one minute (Ribeiro et al, 2013), whereas anesthesia of the snook (Centropomus undecimalis) (7.63 ± 0.15 g) at one minute was estimated to require 117 mg L -1 of this compound (Bernardes Júnior, Nakagome, Mello, Garcia, & Amaral Júnior, 2013). These results show that the pearl cichlid is resistant to eugenol when compared to other species (Table 2).…”

Anesthesia reduces the handling process duration and prevent fish injuries. The anesthetic effect and ideal concentrations of eugenol and tricaine methanesulfonate (MS-222) were tested for pearl cichlid (Geophagus brasiliensis) juveniles with an average weight of 4.4 g in water at 24ºC. The criterion for determining the optimal dose considered an induction time of one minute. Experiment 1 tested the concentrations of 25, 75, 150 and 300 mg L-1 of eugenol. The best results were obtained at doses of 150 and 300 mg L-1. Experiment 2 aimed to establish a more accurate result by testing the concentrations of 180, 210, 240 and 270 mg L-1, and led to an estimation of 217 mg L-1 of eugenol to induce anesthesia in one minute. Experiment 3 evaluated 200, 300, 400, 500 and 600 mg L-1 of tricaine, of which the concentration of 294 mg L-1 was estimated to induce anesthesia in one minute. No significant differences were observed for recovery times when using either of the anesthetics. No mortality was observed within 24 hours after the experiments for any concentration of the anesthetics. The present study recommends 217 mg L-1 of eugenol or 394 mg L-1 of tricaine for anesthesia of the pearl cichlid.

“…Eugenol is a natural product obtained from the distillation of the extract of clove (Eugenia caryophyllata) leaves, stems, and roots . The efficiency of eugenol has been observed for several species, such as rainbow trout (Oncorhynchus mykiss; Keene et al, 1998), pacamã (Lophiosilurus alexandri; Ribeiro et al, 2013), Nile tilapia (Oreochromis niloticus; Vidal et al, 2008;Ribeiro et al, 2015b), matrinxã (Brycon cephalus; Barbosa et al, 2007;Vidal et al, 2007), pacu (Piaractus mesopotamicus; Gonçalves et al, 2008), lambari (Astyanax altiparanae; Pereira-da-Silva et al, 2009), silver catfish (Rhamdia quelen; Cunha et al, 2010;Gomes et al, 2011), and fat snook (Centropomus parallelus; Souza et al, 2012).…”

Menthol and eugenol as natural anesthetics for early juveniles of curimba

et al. 2018

The objective of this study was to evaluate menthol and eugenol as anesthetics for early juveniles of curimba, Prochilodus lineatus. Juveniles of 4.0±0.5 g and a total length of 8.8±0.1 cm were exposed to the anesthetics menthol (20, 30, 40, 50, 60, 70, and 80 mg L −1 ) and eugenol (20, 30, 40, 50, 60, and 70 mg L −1 ) up to deep anesthesia. The anesthetic effects were evaluated measuring the induction time to deep anesthesia (characterized by loss of equilibrium, absence of swimming, reduction of opercular movements, and responses only to intense tactile stimuli), recovery time, time to appetite return, and mortality rate after 96 h of procedure. The concentrations between 60 to 80 mg of menthol L −1 provided the lowest time of induction. Increased concentrations led to a decrease in recuperation time. The concentrations between 50 to 70 mg of eugenol L −1 provided the lowest induction times; however, recovery time was not affected by eugenol concentrations. The return to appetite was observed 24 h after anesthesia, while the survival after 96 h was >90%. Concentrations of 60 and 50 mg L −1 of menthol and eugenol, respectively, are recommended for effective anesthesia with limited side effects.

“…Para os outros estágios de sedação, exceto para a permanência no estágio normal, quanto maior foi à dose, menor foi o tempo de permanência nos estágios avaliados, fenômeno constatado também em outros experimentos que utilizaram o eugenol como anestésico para outros peixes (Façanha and Gomes, 2005;Souza et al, 2012;Ribeiro et al, 2013). Este efeito está relacionado ao fato de a solução de eugenol (10 %) ser adicionada na água e quanto maior a dose, maior será a concentração do anestésico na água, o que potencializa o efeito do sedativo acelerando a anestesia completa e reduzindo o tempo de permanência nos estágios de sedação intermediários.…”

Eugenol como anestésico para oscar, Astronotus ocellatus

et al. 2015

View full text Add to dashboard Cite

A utilização de anestésicos durante práticas de manejo na piscicultura é considerada uma medida mitigadora do estresse dos peixes. A espécie utilizada no experimento, o oscar, é um peixe nativo da Bacia Amazônica de grande importância para a piscicultura ornamental e amplamente difundida na aquariofilia mundial. O objetivo deste trabalho foi avaliar o efeito anestésico do eugenol sobre juvenis de oscar. Foram utilizados juvenis com peso de 4,61 ± 0,83 g e comprimento total de 6,36 ± 0,32 cm submetidos a diferentes concentrações de eugenol na água, em aquários distintos e posteriormente foi observada sua recuperação em aquários sem eugenol. Foram avaliadas quatro concentrações de eugenol: 40; 60; 80 e 100 mg/L. Os valores referentes ao tempo de permanência nos estágios de sedação e recuperação, bem como o tempo para completa sedação e retorno à natação normal foram avaliados e analisados via ANOVA (P
