“…This same EO presented anesthetic activity in silver catfish at concentrations ≥100µL L -1 (CUNHA, et al, 2017). In P. canaliculata, the relaxing effect was obtained from 250µL L -1 (10% efficacy), but only produced a satisfactory effect at a higher concentration (750µL L ) were also necessary for the relaxation of Haliotis iris (AQUILINA & ROBERTS, 2000) and Pomacea paludosa (GARR et al, 2012), respectively.…”

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.

“…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).…”

“…Net ion fluxes provided a good correlation with the stress of transport for silver catfish (Becker et al, 2012(Becker et al, , 2013Parodi et al, 2014;Zeppenfeld et al, 2014;Garcia et al, 2015). Sedation with eugenol and the EOs of L. alba and A. triphylla also reduced ammonia excretion and ion loss in silver catfish (Becker et al, 2012(Becker et al, , 2016Parodi et al, 2014;Zeppenfeld et al, 2014), methanolic extract of Condalia buxifolia and the EOs of Cunila galioides and Origanum majorana decreased ion loss in silver catfish (Becker et al, 2013;Cunha et al, 2017). Eugenol also reduced Cl − efflux during and after transport of Salmo salar (Iversen et al, 2003).…”

“…This experiment lasted 8 h because it is the usual time of transport of juveniles in South Brazil (Tondolo et al, 2013;Cunha et al, 2017) and the concentrations chosen were those which only induced sedation in the anesthetic induction experiment. Groups of fish were also exposed to water (control) and ethanol (1800 μL L −1 ).…”

This study investigated the anesthetic effect of the essential oils (EOs) from the peel of Citrus x aurantium (EOCA) and Citrus x latifolia (EOCL) on silver catfish Rhamdia quelen. Fish were exposed to different concentrations of EOCA and EOCL to determine time of anesthesia induction and recovery. Induction of anesthesia was observed in all fish exposed to 400, 600 or 800 μL L−1 EOCA and 300, 400 or 500 μL L−1 EOCL. Another group of fish were exposed for 8 h to 50, 100, or 200 μL L−1 of either EOs. Overall, fish exposed to ethanol and both EOs presented higher ventilatory frequencies (VF) than the control group throughout the 8 h of exposure. Net ion (Na+, K+ and Cl−) effluxes and ammonia excretion were significantly lower in fish exposed to 50, 100 or 200 μL L−1 of either EOs compared to control fish. Mortality was 37% in fish exposed to 200 μL L−1 of either EOs after 8 h. These findings suggest that EOCA and EOCL are useful anesthetics and sedatives for Rhamdia quelen, but their usefulness as alternatives to reduce stress in fish transportation at the lower concentrations tested (50-100 µL L−1) deserves further study.

“…(Bakkali et al, 2008;Santos, 2010;Sharifi-Rad et al, 2017). Many of these bioactive molecules are found at low concentrations (less than 1%), while a few of them are major compounds that can represent up to 70% of the total volume of oil and are mainly responsible for the bioactive effects of the EO (Bakkali et al, 2008;Cunha et al, 2017). Several of these secondary metabolites of medicinal plants present diverse antiparasitic activity (Bakkali et al, 2008;Soares and Tavares-Dias, 2013;Romero et al, 2014, Valero et al, 2015Hashimoto et al, 2016, Soares et al, 2016Sharifi-Rad et al, 2017).…”

-This review article focuses on current knowledge about in vitro and in vivo experimentation relating to use of essential oils (EOs) to combat fish parasites. In addition, we discuss the existing methodologies used in studies to determine the antiparasitic activity of EOs, along with their toxicity and major compounds. The methodological approaches used to describe the anthelmintic properties of EOs were demonstrated. The consistency of their activity and thus their potential use for fish ectoparasites (in vitro and in vivo) and endoparasites (in vitro) control was reviewed. There is a clear need to find EOs and active agents of EOs to treatment in vivo against endoparasites of fish. Thus, progress may be achieved through considering the beneficial aspects of EOs when their complementarity and potentiality are exploited. EOs are therefore viable alternative sources of therapeutic products against fish parasites. On the other hand, use of chemotherapeutics has been increasingly questioned, such that constant environmental and consumer concerns regarding them now exist. The synergistic functions of EOs, in comparison with the action of one or two major compounds of these oils, seems unquestionable. It is possible that their activity is modulated by several molecules of the major compounds. Lastly, EOs are bioactive products that are viable sources of therapy against fish parasites. Although more than 3000 EOs are known, less than 0.4% of them have been tested on fish parasites. Thus, it has become clear that more studies testing these therapeutic alternatives are required, in order to evaluate the antiparasitic potential of other EOs for controlling fish parasites and to maximize their benefits to hosts.
