“…The present study revealed that induction time of anaesthesia in H. kurali decreased significantly with increasing concentrations of 2-phenoxyethanol (p<0.05), which are consistent with previous studies employing 2-phenoxyethanol in Cyprinus carpio (Linnaeus, 1758;Josa et al, 1992), Carassius auratus (Linnaeus, 1758;Weyl et al, 1996), Diplodus sargus, Diplodus puntazzo, Solea senegalensis (Weber et al, 2009) and Carasobarbus luteus (Kaya and Faith, 2011). The different stages of induction (I 1 , I 2 , I 3 ) and recovery (R 1 , R 2 , R 3 ) observed in H. kurali are presented in Table 1.…”

“…An induction time of 180 sec or less and complete recovery within 300 sec suggested by Marking and Meyer (1985) was employed to assess the induction and recovery stages in the H. kurali. Dosages of anaesthesia adopted for various teleosts (Weber et al, 2009) was adopted as the base information and four concentrations of 2-phenoxyethanol (300, 400, 500 and 600 μL LG 1 ) were selected to assess the inducement of anaesthesia in H. kurali. Both treatment and recovery water were taken from the holding tank, where the fish were maintained and both the systems were aerated throughout the study duration.…”

“…2-phenoxyethanol, a common fish anaesthetic is widely applied in sedation and transportation of fish (Guo et al, 1995). The effective anaesthetic concentration of 2-phenoxyethanol in a number of fish species have been reported to range between 200-600 µL LG 1 (Gilderhus and Marking, 1987;Guo et al, 1995;Weber et al, 2009;Pawar et al, 2011). Anaesthetising the fish is a practical option for facilitating ease of handling, improved egg yield and breeding response, besides significantly lowering brood mortality rates.…”

Hypselobarbus kurali, one of the most demanded fresh water hill stream fish belonging to the family cyprinidae. In the case of brood H. kurali, injuries inflicted to the sudden death of the fish often pose a major problem. When large brood fish are involved, it can lead to incomplete voiding of eggs and mortality in most cases. Anaesthetizing the fish is a practical option for facilitating ease of handling, improved egg yield and breeding response, besides significantly lowering brood mortality rates. In this context, detailed studies were conducted on the use of a commonly employed anaesthetic 2-phenoxyethanol, in the handling and transportation of the fresh water hill stream fish Hypselobarbus kurali. Four levels of anaesthetic were tried viz., 300, 400, 500 and 600 µL LG 1 . The efficacy of the anaesthetic was assessed by considering four stages of induction (I 1 , I 2 , I 3 and I 4 ) and three stages of recovery (R 1 , R 2 and R 3 ). In the present study, the lowest induction time (<180 sec) was observed at 500 µL LG 1 and therefore, this dose was considered as the lowest effective concentration for anaesthesia in H. kurali. At 500 µL LG 1 , the time to reach anaesthesia stage (I3) of induction (159±13 sec) and recovery (R3) time (133±16 sec) was significantly different (p<0.05) from the other dosages 400 µL LG 1 ( 193±14 sec), 300 µL LG 1 ( 216±78 sec) and 600 µL LG 1 (190±14 sec).

“…The use of anesthetics enhances safety for both fish and farmer during aquaculture operations and management procedures. It allows farm routine practices to be performed with minimum stress for the fish [7][8][9]. Recently, application of clove oil as anesthetic in farmed fish is on the increase, this is because it is safe, cheap, and nontoxic to the fish and environment.…”

Background and Aim: The intensive nature of aquaculture has subjected fish to a number of stressors in the culture medium, anesthetics are widely used to minimize the issue of stress during farming operations and activities. Clove oil is a well known, established and acceptable anesthetics commonly used in aquaculture, this anesthetics is not readily available in developing countries, thus leaving the fish farmers with option of using the locally available plant extracts as anesthetic agent in fish culture. This study therefore assessed the efficacy of aqueous extracts of clove seed and its effect on hematological parameters of the fish.Methods: A total of 300 Clarias gariepinus comprises of 150 juveniles and 150 adult fish were exposed in triplicates to aqueous extracts of clove seed at concentrations of 5.0, 10.0, 15.0, 20.0 and 25.0mg/l at the rate of 10 fish per tank for both juveniles and adult fish. Induction time (Time taken for the fish to be completely anaesthetized) and recovery time (Time taken for the fish to resume normal swimming) was monitored using stop watch. Also, the effect of the extracts on water quality, survival and hematological parameters of the fish were evaluated using standard methods. Results:The result obtained revealed that the induction time indicated a size related response with the adult fish significantly (P<0.05) higher than the juveniles at all concentration of exposure. However, reverse was the case in recovery time, as the recover times in juveniles were higher than the adult fish. The survival was 100% in both sizes. Significant alterations were recorded in the haematological variables of the fish, which was more pronounced at higher concentrations of the extracts.

“…Os estudos sobre o uso de substâncias naturais, como o mentol (Façanha e Gomes, 2005;Gonçalves et al, 2008) e o eugenol (Vidal et al, 2008;Weber et al, 2009) como anestésico em aqüicultura tem origem na necessidade de se encontrar produtos alternativos eficazes em substituição aos anestésicos sintéticos legalmente utilizados. Estas substâncias naturais, geralmente apresentam baixo custo e fácil aquisição (Roubach et al, 2005), justificando assim o desenvolvimento de protocolos adequados para sua utilização em peixes.…”

Endereço para correspondência: Erivânia Gomes Teixeira: vaniaengp@yahoo.com.br RESUMO: O objetivo com o trabalho foi avaliar o mentol como anestésico para diferentes classes de tamanho de tilápia do Nilo. Foram avaliadas três classes de tamanho: alevinos, juvenis e adultos, submetidas a seis concentrações de mentol (30, 60, 120, 180, 240 e 300 mg L-1), expostos individualmente por 10 minutos à solução anestésica e acompanhados durante a indução e recuperação. Para os alevinos, juvenis e adultos as concentrações recomendadas para atingirem o estágio de anestesia profunda foram de 60 (124,8±6,9 s), 180 (202.7 ± 17.0 s) e 240 (210,5 ± 17,3 s) mg L-1, respectivamente. Os tempos de recuperação para as concentrações supracitadas foram, na mesma ordem, de 306,2 ± 27,1, 202,7 ± 17,0 e 328,6 ± 32,0 s. Para indução ao estágio de anestesia cirúrgica, as concentrações foram de 60 (172,8±10,1 s), 120 (313,7 ± 14,7 s) para alevinos e juvenis, respectivamente. A utilização do mentol como anestésico mostra-se eficaz, variando entre as diferentes classes de tamanho de tilápia do Nilo.Palavras-chave: aqüicultura; anestesia; estresse. MENTHOL AS AN ANESTHETIC FOR DIFFERENT SIZE CLASSES OF NILE TILAPIAABSTRACT: The aim of this study was to evaluate the menthol as an anesthetic for various size classes of Nile tilapia. We evaluated three size classes: fingerlings, juveniles and adults, subjected to six concentrations of menthol (30, 60, 120, 180, 240 and 300 mg L-1), individually exposed for 10 minutes to the anesthetic solution and monitored during the induction and recovery. To fingerlings, juveniles and adults the recommended concentrations to reach the stage of deep anesthesia were 60 (124,8 ± 6,9 s), 180 (202,7 ± 17,0 s) and 240 (210,5 ± 17,3 s) mg L-1, respectively. The recovery times for the concentrations above were in the same order, from 306,2 ± 27,1, 202,7 ± 17,0, and 328,6 ± 32,0 s. For the induction stage of surgical anesthesia, the concentrations were 60 (172,8 ± 10,1 s), 120 (313,7 ± 14,7 s) for fingerlings and juveniles, respectively. The use of menthol as an anesthetic is effective, varying between the different size classes of Nile tilapia.
