“…The measurement of ventilatory frequency (VF) is a non-invasive method that indicates possible physiological changes in the respiratory system of fish caused by acute stressors, such as the manipulation and use of anesthetics (ALVARENGA & VOLPATO, 1995;BARRETO & VOLPATO, 2004;TONI et al, 2014;SILVA et al, 2019;ANANIAS et al, 2022). In the present study, VF during induction and recovery from anesthesia were reduced for fish anesthetized with 150 µL L -1 EOHR, which corresponds to the lowest concentration to be recommended for juveniles of C. macropomum.…”

“…Different techniques are being used to mitigate the effects of stress caused by routine practices in fish farms, including the use of anesthetics (SINK & NEAL, 2009;SOUZA et al, 2019;FERREIRA et al, 2021a;ANANIAS et al, 2022). Anesthetic compounds have been a tool used to promote complete immobilization of fish and/or prevent the physiological effects of stress on animals, providing greater safety for both the animal and the handler (VELISEK & SVOBODOVA, 2004;ROSS & ROSS, 2008).…”

This study evaluated the effectiveness of the essential oil of Hesperozygisringens (EOHR) for anesthesia of Colossomamacropomum by documenting hematological and blood biochemical responses after biometric handling. In Experiment 1, juveniles (14.12 ± 3.53 g) were exposed to different concentrations of EOHR: 0 (control), 75, 150, 300 and 450 µL L-1 (n=10 fish for each concentration), to determine times for induction and recovery from anesthesia, as well as its effects on ventilatory frequency (VF). Based on these results, Experiment 2 evaluated the effects of 0 (control), 75 (with induction and recovery times outside that recommended for fish anesthesia) and 150 µL L-1 EOHR (within recommended times) on hematological and biochemical variables of juveniles (20.52 ± 3.47 g) after anesthesia and after 24 h of recovery (n = 6 fish for each concentration and collection time). Survival was 100%. Induction time showed a quadratic effect of EOHR concentration. Recovery time did not differ among EOHR concentrations. Concentrations between 150 and 450 µL L-1 EOHR caused rapid induction (< 3 min) and recovery (< 5 min). EOHR concentration affected VF. The concentration of 150 µL L-1 EOHR had little influence on hematological and biochemical parameters of C. macropomum of 20 g.

“…Thus, based on these responses and also due to anaesthetic induction occurring in <4 min at the concentration of 80 mg L −1 , and recovery in <10 min, M. piperita oil was TA B L E 1 Anaesthetic activity of essential oils for native fish of Brazil (Continues) considered an efficient anaesthetic for the species, since, according to toxicity tests, it presented a good safety margin for the fish (Spanghero et al, 2019). 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).…”

Aquaculture remains in full development around the world and is still considered to be the sector with the highest growth in comparison with other food production sectors. Global aquaculture production was 110.2 million tonnes in 2016, and of this total 54.1 million tonnes were fish (FAO, 2018). In Brazil, the scenario is not so different; fish production reached 758,006 tonnes in 2019, and tilapia (Oreochromis sp.) continued to hold first place with a production of 432.149 tonnes (Peixe BR, 2020). The production of native fish, such

“…Anesthetics are used in aquaculture to reduce stress and prevent physical injury during handling procedures and transport (Ananias et al, 2022; Hoseini et al, 2021; Yousefi et al, 2022). The most common anesthetics used in aquaculture are benzocaine, quinaldine, tricaine methanesulphonate (MS‐222), and 2‐phenoxyethanol (Ananias et al, 2022; Priborsky & Velisek, 2018). However, these anesthetics cause undesirable effects such as stressors, gill irritation, hyperactivity, excessive mucus secretion, and are also expensive (Aydın & Barbas, 2020; Gilderhus & Marking, 1987; Hoseini et al, 2021; Palić et al, 2006).…”

In this study, anesthetic effects of Ocimum basilicum and Eucalyptus globulus essential oils were investigated on rainbow trout, Oncorhynchus mykiss. Fish (average 10 g) were exposed to 20, 50, 70, 100, 150, 200, 300, 400, 500, and 600 mg L À1 essential oils, anesthesia induction, and recovery times were recorded separately for each fish. Acute toxicities of essential oils (10 min LC 50 concentration) on rainbow trout were determined at 70-400 mg L À1 . In addition, histopathological effects of the essential oils in fish tissues were determined after deep anesthesia. As a result of this study, O. basilicum at 300 mg L À1 dose and E. globulus essential oils at 400 mg L À1 dose showed ideal anesthetic effects on rainbow trout. Anesthesia induction (stage 4) and recovery times at this concentration for E. globulus were found as 186 and 117.5 s, respectively. Anesthesia induction (stage 4) and recovery times were 220.5 and 61 s for this concentration in O. basilicum essential oil, respectively.The toxic effects of essential oils for rainbow trout were not found. No pathological finding in gill, liver, and kidney
