“…This effect was expected, since these compounds have an anesthetic effect in fish (GOMES et al, 2011, SILVA et al, 2015CUNHA, et al, 2017). Eugenol also presented anesthetic activity in crustaceans (PARODI et al, 2012).…”

“…Almost all anesthetic substances used in shellfish are synthetic products such as benzocaine, MS-222 and 2-phenoxyethanol, and the minority are plant extractives (GARR et al, 2012). Essential oils (EOs) of Lippia alba and Aloysia triphylla (PARODI et al, 2012), for example, and isolated substances such as eugenol (GOMES et al, 2011;PARODI et al, 2012) and linalool (HELDWEIN et al, 2014) are effective to anesthetize fish and shrimps. Thus, we can assume that EOs may also be effective in mollusks.…”

This study evaluated the potential relaxing and/or molluscicidal effects of eugenol and essential oils of Origanum majorana, Ocimum americanum, Hesperozygis ringens, and Piper gaudichaudianum in the gastropod Pomacea canaliculata. Compounds were tested at concentrations of 100, 250, 500, and 750µL L-1 to evaluate the relaxing effects. In the second experiment, animals were exposed to 10, 25, and 50µL L-1 of essential oils of H. ringens and P. gaudichaudianum for a period of 24h for the evaluation of molluscicidal effects. Eugenol and essential oils of O. majorana and O. americanum showed relaxing effects at ≥250µL L-1, but the essential oils of H. ringens and P. gaudichaudianum did not promote relaxing or molluscicidal effects within the times and concentrations studied. Therefore, only eugenol and the essential oils of O. majorana and O. americanum can be used for relaxation purposes in P. canaliculata.

“…Studies have demonstrated that eugenol is an efficient inducer of anesthesia for carps (C. carpio) when used at doses lower than 75 mg L -1 and recommended dosage of 37.5 mg L -1 for anesthesia this specie, to avoid drug toxicity (BITTENCOURT et al, 2013). For South American catfish (R. quelen) GOMES et al (2011) indicated a dosage of 40 ml L -1 is sufficient to induce anesthesia and compensate for the effects of size of fish and water quality. In the studies of HONCZARYK and INOUE (2009) was reported that doses of 30 and 60 mg L -1 applied by spraying in gills of arapaima (Arapaima gigas) were effective for the management of this species.…”

“…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,...

“…The concentration and efficacy required for induction may vary among species, age, size, gender and even among the parameters of water quality (Walsh and Pease 2002, Woody et al 2002, Gomes et al 2011). According to the literature, proper immersion anesthesia may decrease the incidence of adverse effects and lead to a milder recovery (Acerete et al 2004, Zahl et al 2009).…”

In aquaculture, activities with anesthetic compounds are usually used in order to ensure the welfare of farmed fish, allowing handling out of water with decreased trauma by stress. Presently, there is no information about anesthetic action of eugenol in early life stages of Nile tilapia (Oreochromis niloticus). The objective of this study was to evaluate different concentrations of eugenol for larvae and juveniles of Nile tilapia. Sixty animals were used for each group of weight, group I = 0.02 g; group II = 0.08 g; group III = 0.22 g; group IV = 2.62 g; and group V = 11.64 g. The eugenol concentrations tested were 50, 75, 100, 125, 150 and 175 mg L -1 . No mortality was reported during the tests with eugenol. Tilapia larvae with 0.02 g and juveniles around 11.64 g can be anesthetized with eugenol concentrations between 150 and 175 mg L -1 , since they determine the shortest sedation time (23 and 72 seconds, for the group of lowest and highest weights, respectively).
