This study aimed to verify the sedative and anaesthetic effect of the essential oils of basil (Ocimum basilicum) (EOOB) and lemongrass (Cymbopogum flexuosus) (EOCF) in Nile tilapia juveniles. The fish were transferred to aquaria containing different concentrations of each essential oil: 10, 25, 50, 100, 200, 400 and 600 μL L-1. The time of sedation ranged from 7 to 31 seconds and the recommended concentration was 10 or 25 μL L-1 for both essential oils. The best times for anaesthesia and recovery were found for the concentrations of 400 μL L-1 for EOOB (135.2 and 199.1 seconds, respectively) and 600 μL L-1 for EOCF (327.1 and 374.8 seconds, respectively). In conclusion, we recommend the use of EOOB and EOCF for the sedation and anaesthesia of Nile tilapia at concentrations of 10-25 (for both), 400 and 600 μL L-1, respectively.
本研究旨在验证罗勒（Ocimum basilicum）（EOOB）和柠檬草（Cymbopogum flexuosus）（EOCF）精油对尼罗罗非鱼幼鱼的镇静和麻醉作用。将鱼转移到含有不同浓度每种精油的水族箱中：10、25、50、100、200、400和600 μL L-1。镇静时间为7至31秒，两种精油的推荐浓度均为10或25 μL L-1。对于EOOB浓度为400 μL L-1（分别为135.2和199.1秒）和EOCF浓度为600 μL L-1（分别为327.1和374.8秒）时，发现了最佳麻醉和恢复时间。总之，我们建议分别以10-25（两者）、400和600 μL L-1的浓度使用EOOB和EOCF对尼罗罗非鱼进行镇静和麻醉。
