摘要:
在水温为20℃ ± 0.5℃条件下，丁香油对匙吻鲟幼鱼的麻醉作用。根据鱼体在最终麻醉状态和复苏过程中的行为特征，把麻醉程度分为6个时期，复苏过程分为4个时期。随着丁香油浓度的增加，鱼体在轻度镇静期时，呼吸频率略微增加，在2期时的呼吸频率和初始呼吸频率相差不多，到4期时呼吸频率才明显下降。丁香酚麻醉匙吻鲟幼鱼的有效浓度为37.83~44.83 mg/L。结果提示，丁香油在用于匙吻鲟的人工操作时，应准确掌好麻醉剂量和麻醉时间，避免麻醉过度造成损失。This article presents the studies on the anaesthetic effect of clove oil on juveniles Polyodon spathuln at 20℃ ± 0.5℃. According to the behavior characteristic of the fish in the final anaesthetic stage and the recovery process, the anaesthetic degrees could be divided into six stages, and the recovery process could be divided into four stages. The breath frequency of the fish slightly increased when the fish was in the stage 1. The breath frequency of the fish of stage 2 was similar to initial group, and declined until in the stage 4. The effective concentrations of clove oil on juvenile Polyodon spathuln were 37.83 - 44.83 mg/L. The results indicated that when clove oil was used for Polyodon spathuln in the process of manual breeding, it was necessary to control the dose and anaesthesia time of eugenol to reduce the death rate.
