“…Similarly, Bernardes‐Júnior et al . () reported a strong relationship between eugenol concentration and induction time ( R ² = 0.899, IT = 4785C −0.9190 ) in juvenile common snook ( Centropomus undecimalis ). However, they did not observe any consistent relationship between recovery time and anaesthetic concentration may be due to a high variability in response time observed in all treatments during recovery.…”

Anaesthetic efficacy of eugenol was investigated on Flowerhorn (Amphilophus labiatus 9 Amphilophus trimaculatus). A total of 104 fish with average weights of 12 AE 2.5, 28 AE 5 and 53 AE 5.1 g were subjected to 25-200 mg L À1 eugenol and behavioural responses as well as induction and recovery times were recorded. Induction and recovery times were significantly affected by eugenol concentration as well as fish weight (P < 0.05). Generally, 49.9-127.3 s after exposure to 50-200 mg L À1 eugenol, fish reached stage 3 anaesthesia (suitable for general handling). Fish entered stage 4 anaesthesia (suitable for surgery and blood sampling) over 57.3-140.4 s post exposure to such concentrations. Recovery time was 91.7-312 s in all weight classes for all eugenol concentrations. Mortality (23%) was only observed in 12-g fish when were subjected to 200 mg L À1 eugenol. This study showed the behavioural response of Flowerhorn to anaesthesia and eugenol efficacy as an anaesthetic in this important ornamental species. The general quadratic equation revealed that concentrations of eugenol and fish size along with their interactive effects have significantly contributed to the model, with concentration recording the highest beta value in all models (b = À0.809, À0.818 and À0.909, P = 0.000). According to the results, minimum eugenol concentration to induce anaesthesia in less than 3 min was 50 mg L À1 .

“…In Brazil there are recent reports of using eugenol (2-methoxy-4-(2-propenyl)phenol), the main component of clove oil (70-90% by weight) or just clove oil as an anesthetic for several species like Centropomus undecimalis (BERNARDES JÚNIOR, et al, 2013), Pimelodus britskii (BERTOZI JÚNIOR et al, 2014), Rhamdia quelen (CUNHA et al, 2010;GOMES et al, 2011;BECKER et al, 2012;SUTILI et al, 2014), Oreochromis niloticus (MOREIRA et al, 2010;, Cyprinus carpio (BITTENCOURT et al, 2013), Colossoma macropomum (INOUE et al, 2011), Pseudoplatystoma reticulatum (SANTOS SANCHEZ et al, 2014b), Gymnotus aff. inaequilabiatus (PÁDUA et al, 2012), Brycon hilarri (FABIANI et al, 2013) among others.…”

The eugenol is the active ingredient of clove oil and it has shown to be effective and safe as fish anesthetic. In this study were evaluated the effects of different concentrations of eugenol for anesthesia, recovery time, blood glucose and hematocrit percentage of pearl cichlid (Geophagus brasiliensis) juveniles. Concentrations of 50, 80, 100, 120, 150, 170 and 200 mg L -1 eugenol were evaluated in terms of time to achieve the different stages of anesthesia and recovery in a completely randomized design (CRD) with 12 repetitions. These results were tested using the Kruskal-Wallis test with subsequent Dunn test. The evaluated concentrations had anesthetic action of the deep induction 172.57 ± 25 s (50 mg L -1 ) and the period of full recovery of 516.25 ± 102 s (200 mg L -1 ), with statistical difference between the treatments at all the stages. The eugenol effect on blood glucose and on hematocrit percentage at 0 h after deep anesthesia was evaluated for concentrations of 0; 50; 80; 100; 150; 200 mg L -1 , in a completely randomized design with five replications, and the results were assessed by One-Way ANOVA. Glucose and percentage of hematocrit: no statistically significant differences (P>0.05) were observed for these variables. All concentrations of eugenol showed to be effective as an anesthetic for G. brasiliensis and did not affect the survival, blood glucose and the percentage of hematocrit. To minimize adverse effects and achieve faster recovery is indicate the use of 50-80 mg L -1 of eugenol for pearl cichlid juveniles.Keywords: anesthesia; clove oil; fish; pearl cichlid UTILIZAÇÃO DE EUGENOL COMO ANESTÉSICO EM JUVENIS DE Geophagus brasiliensis RESUMOO eugenol, substância ativa do óleo de cravo, tem demonstrado ser eficiente e seguro como anestésico para peixes. Neste estudo foram avaliados os efeitos de diferentes concentrações de eugenol na anestesia, tempo de recuperação, glicemia e percentual de hematócrito de cará (Geophagus brasiliensis). Concentrações de 50, 80, 100, 120, 150, 170 e 200 mg L -1 de eugenol foram avaliadas em relação aos tempos para atingir os diferentes estágios de anestesia e de recuperação, em desenho inteiramente casualizado (DIC), com 12 repetições. Os resultados foram analisados pelos testes de Kruskal-Wallis e teste Dunn. As concentrações avaliadas produziram ação anestésica em período de indução profunda de 172,57 ± 25 s (50 mg L -1 ) e no período de total recuperação de 516,25 ± 102 s (200 mg L -1 ), com diferença estatística entre os tratamentos para todas as fases avaliadas. Foi avaliado o efeito do eugenol sobre a glicose no sangue e sobre o percentual de hematócrito, em 0 h após anestesia profunda, nas concentrações 0, 50, 80, 100, 150 e 200 mg L -1 , em DIC com cinco repetições, e os resultados avaliados através de ANOVA uma via. Não foram observadas diferenças estatísticas significativas (P>0,05) para glicose e hematócrito. Todas as concentrações de eugenol avaliadas apresentaram eficiência como anestésico para G. brasiliensis e não afetaram a sobrevivência,...

“…while at 300 lL −1 it resulted in sedation (stage II) only and concentration from 400 lL −1 resulted in progressive anaesthesia. Deep anaesthesia (stage IV) is the stage normally used for performing biometric procedures, induced breeding, and handling procedures [2,28]; therefore, in S. denisonii, the minimum effective concentration of 2-phenoxyethanol which meets the requirements for handling during hatchery management was 500 lL −1 . The recovery time was directly proportional to increasing doses of 2-phenoxyethanol ( < 0.05).…”

Efficacy of 2-phenoxyethanol for redline torpedo fish exposed to five concentrations (200, 300, 400, 500, and 600 lL −1 ) was evaluated. The time periods necessary for each characteristic stage of induction and recovery were recorded. Results indicated that the induction time of the fish exposed to five anaesthetic concentrations significantly ( < 0.05) decreased with increasing concentration but recovery time was independent of concentration. Concentration of 500 lL −1 (induction time: 173 ± 7 and recovery time: 129 ± 41 seconds) was determined as the minimum effective concentration that induces anaesthesia in less than 3 minutes.
