Abstract: 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) fo… Show more

“…In line with previous findings with EOs of L. alba (Cunha et al, 2010), N. megapotamica (Tondolo et al, 2013) and A. triphylla (Gressler et al, 2014;Parodi et al, 2014), increasing concentrations of both EOC and EOO proportionally decreased sedation and anesthesia induction time. As stated by Marking, Meyer (1985), an ideal fish anesthetic should induce anaesthesia in less than 3 min, and recovery should occur in 5 min.…”

“…In the Brazilian flounder (Paralichthys orbignyanus), the EO of Aloysia gratissima elicited paralysis and mortality during anesthesia (Benovit et al, 2012). Other undesirable effects have been reported in fish exposed to natural anesthetics: increased lactate content with N. megapotamica, L. alba and H. ringens EOs (Tondolo et al, 2013;Toni et al, 2014), elevated glucose levels with mentol (Simões, Gomes, 2009;Sanchez et al, 2014), increased plasma cortisol with clove oil (Bressler, Ron, 2004;Weber et al, 2011) and increased hematocrit and disturbances of hydromineral balance with A. triphylla EO (Gressler et al, 2014). Thus, as any other product used in fish farming, safety and efficacy of EOs should be carefully investigated for individuals of a given species.…”

“…Natural oils are becoming increasingly used as anesthetics due to their low toxicity and risks to operators (Façanha and Gomes, 2005;Tondolo et al, 2013). In this context, menthol has been used as an anesthetic for marine invertebrates and fish (Ross and Ross, 1999;Simões and Gomes, 2009).…”
