“…In aquaculture, the use of anaesthetic reduces stress from handling and transportation, as well as when fish are marked, tagged and sampled for weight and length parameters and can sometimes lead to stock mortality. Some common anaesthetics used in fish include clove oil (Masoumeh and Masuomeh 2018), sodium bicarbonate (Altun et al 2009;Avillanosa et al 2019;Hasimuna et al 2019), benzocaine (Bolasina et al 2017), 2-phenoxyethanol (Varkey and Sajeevan 2014), tricaine methanesulfonate or MS-222 and qui-naldine (Ramlochnsingh et al 2014;Shokr and Fathy 2018).…”

Sedation of fish before handling and transporting can help curtail undue stress that can affect their health. This study investigated the effectiveness of sodium bicarbonate (NaHCO3) utilised as an anaesthetic agent for common carp (Cyprinus carpio) with an average weight of 13.5 ± 0.55 g. The experimental fish were grouped and exposed to different concentrations at 0, 40, 45 and 50 g L–1 of NaHCO3 dissolved in water. Fishes were bath-immersed in different concentrations of NaHCO3 solution until such time that they became anesthetised. Results showed that induction time and recovery time increases with increasing NaHCO3 concentration. All fish reached complete anaesthesia in more than 3 minutes under a higher concentration of 50 g L–1. No mortality occurred under any of the concentrations tested. The most optimal concentration leading to complete anaesthesia in 2 minutes and recovery in less than 4 minutes was 45 g L–1. This study showed that NaHCO3 is a potential fish anaesthetic for the common carp.

Simultaneous effect of sex and dose on efficacy of clove oil, tricaine methanesulfonate, 2-phenoxyethanol and propofol as anaesthetics in guppies,Poecilia reticulata(Peters)

We studied the simultaneous effect of sex and dose on anaesthesia efficacy to estimate, if possible, the lowest effective dose (LED) for clove oil, tricaine methanesulphonate (MS-222), 2-phenoxyethanol (2-PE) and propofol in mature guppies. LED is the lowest dose needed to reach A5 stage in a mean time of 3 min, with mean recovery (R5) time of 5 min. We used four doses/anaesthetic: 25, 50, 75 and 100 mg/L for clove oil; 120,140,160 and 180 mg/L for MS-222; 800, 1,000, 1,200 and 1,400 mg/L for 2-PE, and 7.50, 8.25, 10.00 and 11.25 mg/L for propofol. Each dose was tested on 10 females and 10 males. Morbidity, mortality and behavioural changes were checked on two control groups (10 males and 10 females/group). Sedation (A3), A5 and R5 times were recorded. Significant interactive effect dose*sex on A5 time was found for each anaesthetic agent (p dose*sex < .05). Except for MS-222 (p dose*sex = .284), significant interactive effect dose * sex on R5 time was found (p dose*sex < .05). A5 time in females tended to be greater than in males, but, in general, R5 times were longer in males. Body size differences between males and females could explain these differences in MS-222 on A5 time and for clove oil, 2-PE and propofol on R5 time. No dose simultaneous meet LED 0 s conditions relating to both A5 and R5 times; therefore the lowest doses inducing A5 in a mean time of 3 min could be a safe guideline for anaesthetic procedure in both male and females.
