“…The results showed that cineole anaesthetic efficiency in trout is higher than common carp as Mazandarani and Hoseini (2017) reported induction time of~550-150 s at the concentrations of 300-800 ll/L. However, cineole anaesthetic efficacy in trout was lower than a cineole-rich essential oil efficacy in D. labrax and T A B L E 4 Plasma sodium, chloride and calcium levels of rainbow trout anaesthetized with different concentrations of cineole A. regius (Bodur et al, 2018). Such a difference might be due to species difference as reported in previous studies (Cunha & Rosa, 2006 (Benovit et al, 2012) and essential oil of Hesperozygis ringens and Ocotea acutifolia in Rhamdia quelen (Silva et al, 2013).…”

“…At the concentrations of 300-800 ll/L, cineole anaesthetized the fish within 550-100 s with recovery time around 500 s. There is no data about cineole anaesthetic efficacy in other fish species; however, Khumpirapang, Pikulkaew, Anuchapreeda and Okonogi (2018) examined essential oil of Alpinia galangal rhizomes (hydro-distillation) that was rich in cineol (37.4%) to anaesthetize koi carp. The concentrations of 200-800 mg/L anaesthetized the fish within 301-54 with recovery time of 203-388 s. Similarly, Bodur, Afonso, Montero and Navarro (2018) reported that essential oil of Eucalyptus sp. (80.8% cineole) has anaesthetized Dicentrarchus labrax within 150-210 s (at the concentrations of 200 and 300 ll/L), and Argyrosomus regius within 130-210 s (at the concentrations of 150-300 ll/L).…”

“…Eugenol anaesthetic efficacy has been confirmed in several fish species including common carp (Cyprinus carpio), tambaqui (Colossoma macropomum), fathead minnows (Pimephales promelas), pacu (Piaractus mesopotamicus) and iridescent shark (Pangasius hypophthalmus) (Endo, Ohshima, Ogishima & Tanaka, 1972;Gonc ßalves, Santos, Fernandes & Takahashi, 2008;Hikasa, Takase, Ogasawara & Ogasawara, 1986;Hoseini, Rajabiesterabadi & Tarkhani, 2015;Pali c, Herolt, Andreasen, Menzel & Roth, 2006;Roubach, Gomes, Leão Fonseca & Val, 2005). The concentrations of 200-800 mg/L anaesthetized the fish within 301-54 with recovery time of 203-388 s. Similarly, Bodur, Afonso, Montero and Navarro (2018) reported that essential oil of Eucalyptus sp. Cineole is the major component of essential oil in plants of genus Eucalyptus sp.…”

The aim of the present study was to investigate the anaesthetic efficacy and biochemical effects of 1,8-cineole (cineole) in rainbow trout (Oncorhynchus mykiss). The fish were exposed to 200, 300, 400, 500, 600 and 800 ll/L cineole and time of induction of anaesthesia and recovery from anaesthesia were recorded. Thereafter, the fish haematological and biochemical responses to anaesthesia with different concentrations of cineole were studies. Moreover, the haematological and biochemical response of fish anaesthetized for 300 s with either cineole (283 ll/L) or eugenol (25 ll/L) were compared. Cineole at the concentrations of 200-800 ll/L induced stages 2, 3 and 4 anaesthesia within 109-29.3, 226-59 and 418-117 s respectively. Increase in anaesthesia induction time led to higher stress responses and enzymes' activity characterized by elevation in red blood cell (RBC), white blood cell (WBC), blood haematocrit and haemoglobin, and plasma cortisol, glucose and lactate levels, and aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase and creatine phosphokinase (CPK) activities. However, cineole concentrations had no significant effects on plasma alanine aminotransferase (ALT) activity and ions levels. Comparison of cineole with eugenol showed that cineole showed less change in blood RBC and plasma AST, ALP, CPK, cortisol and glucose levels compared to eugenol. In conclusion, cineole is efficient to anaesthetize trout at concentrations of 200-800 ll/L. Increase in cineole concentration shortens anaesthesia induction time, stress response and probably tissue damage. The concentrations of 600-800 ll/L cineol is recommended for rapid sampling as it causes the least stress and enzymatic responses. The present results suggest that cineole causes slightly lower side effects in trout compared to eugenol. K E Y W O R D S anaesthesia, cineole, fish, haematology, stress

Anaesthesia is a widely used tool in fish handling, sampling and surgery in aquaculture; thus, fish anaesthesiology has been studied for a long time. In this case, there are several common anaesthetics in aquaculture, namely tricaine methanesulfonate (a chemical agent) and clove oil (a natural agent). Recently, there was an increasing interest to use herbal materials (other than clove oil) in fish anaesthesia. In this review, current knowledge about the use of herbal anaesthetics has been summarized. To date, essential oils/extracts of different plants have been studied for fish anaesthesia; most of them belong to Lamiaceae, Verbenaceae, Lauraceae and Myrtaceae. In addition, menthol, linalool, myrcene, cineole, globulol, spathulenol, guaiol, caryophyllene oxide, terpinen-4-ol and dehydrofukinone are herbal compounds that their anaesthetic effects have been studied in fish. Compared with clove oil and eugenol as the most common herbal anaesthetic, all tested herbal materials are less efficacious to anaesthetize fish. Some plants' essential oil/extract, namely Aloysia triphylla, Myrcia sylvatica, Lippia alba and Curcuma longa, have beneficial health effects including suppression of physiological and oxidative stress. There is a lack of data in mechanism of anaesthesia and health effects of the herbal anaesthetics, which should be followed in future studies. In addition, most of the current studies have focused on certain fish species such as silver catfish (Rhamdia quelen), tambaqui (Colossoma macropomum) and common carp (Cyprinus carpio), and in most of the studies, essential oils/extracts of South American plants have been used. Thus, there is a need to study other fish and plant species.

BackgroundUsing anaesthetics is an important application in aquaculture especially where the fish transportation, vaccination, grading, sorting activities and many other handling operations have been conducted during the different stages of production periods in the farms or hatcheries.ObjectivesThis study aimed to evaluate the efficacy of oregano essential oil (OO) as an anaesthetic for Nile tilapia and to determine the optimal concentration and post‐application stress effects compared to clove oil (CO).MethodsNile tilapia juveniles were exposed to different concentrations of OO (20–40–60–80–100 mg L−1) and CO (50 mg L−1) for different time periods to determine the optimal concentration and exposure time. After the effective concentration of OO was determined, in the second experiment, stress parameters (glucose, plasma cortisol) were analysed after 0, 2, 6, 12 and 24 h of application. The results compared to the control group and CO results.ResultsThe study found that OO which has carvacrol compound higher than 78% was an efficient anaesthetic for Nile tilapia, and the effective concentration was found to be 60 mg L−1. No significant differences were found between opercular beats in any concentration of OO and CO. Basal glucose level in blood without anaesthesia application and recorded at 39.33 mg dL−1 and significantly lower than OO and CO at first two sampling points, 0 and 2 h (p < 0.05). According to plasma cortisol level results, although CO experimental group showed secondary stress response at 12 h (17.91 ± 4.21 ng mL−1), OO and CO group cortisol levels decreased at 24 h after anaesthesia application 7.13 ± 0.14and 7.01 ± 0.54 ng mL−1, respectively, below the control group cortisol concentration (12.28 ± 1.81 ng mL−1).ConclusionsThese findings have important implications for the aquaculture industry as the use of OO as an anaesthetic could reduce the stress and mortality associated with traditional anaesthetics. Further research is needed to evaluate the efficacy of OO as an anaesthetic agent for other fish species and to determine the optimal concentration and exposure time for different species.
