Abstract: 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 m… Show more

“…In this study, based on preliminary trials (data not shown), anaesthetic concentration of menthol was ranged between 40 and 80 mg/L. Effective anaesthesia concentration of menthol in red‐bellied pacu was 50 mg/L which is agreement with reported for in juvenile fat snook ( Centropomus parallelus ) (Sepulchro, Carvalho, & Gomes, 2016), curimba ( Prochilodus lineatus ) (Medeiros‐Junior et al, 2018) and Pereira‐da‐Silva, Oliveira, and del Nero (2016) in lambari ( Astyanax altiparanae ) and, however, is lower than reported for several fish species. This lower concentration may be explained due to fish size.…”

“…Menthol (1R,2S,5R-2-isopropyl-5-methylcyclohexanol) (Farmacia Colony) was used and dissolved in absolute ethanol, 99% (Merck), to reduce its hydrophobic character (Medeiros-Junior et al, 2018). The stock solution was prepared few minutes before the start of each experiment and added to anaesthetic tanks of 3 L; the water temperature of these tanks was 25°C.…”

“…With the isolated compound menthol, the concentration of 50 mg L −1 induced deep anaesthesia in juvenile L. alexandri , with a reduction in ventilatory frequency during anaesthetic induction and recovery, and it also prevented the increase in plasma glucose after handling (Ananias et al, 2022). In Prochilodus lineatus , anaesthetic induction was observed at concentrations of 60 to 80 mg L −1 , with the recommendation of 60 mg L −1 for deep anaesthesia (Medeiros Junior et al, 2018). Menthol's anaesthetic action is related, in part, to the activation of GABA A receptors, the main inhibitory neurotransmitter of the central nervous system (Zhang et al, 2008).…”
