摘要
研究了在20～21℃水温下丁香酚对半滑舌鳎成鱼的麻醉作用。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。鱼体最终麻醉程度不超过3期时,呼吸频率略微增加,到4期时呼吸频率才明显下降。丁香酚麻醉半滑舌鳎成鱼的有效浓度为40～80mg/L,在此范围内,丁香酚浓度越高鱼体达到4期的麻醉时间越短,但复苏时间没有明显差别。丁香酚浓度在40～60mg/L之间时,最长麻醉保活时间>20min;当丁香酚浓度≥80mg/L时,最长麻醉保活时间<8min,鱼体入麻时间与死亡时间的边界很窄,麻醉后应立即进行复苏,否则会导致鱼体死亡。
This article presents the studies on the anaesthetic effect of clove oil on adult Cynoglossus semillaevis Gunther at 20-21℃. 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 final anaesthetic stage 1-3, and clearly declined until in the stage 4. The effective concentrations of clove oil on adult Cynoglossus semillaevis Gunther were 40-80 mg/L. Within this concentration range, the higher the concentration of clove oil, the shorter was the anaesthetic rime needed, for reaching stage 4,whereas the recovery time did not show ally significant differences. When the clove oil concentrations were 40-60 mg/L, the longest survival time for the fish was over 20 minutes. When the concentration was 980 mg/ L, however, the longest survival time became less than 8 minutes. In addition, the time margin in between anaesthesia and death was very narrow. The fish should be restored immediately after being anaesthetic, otherwise, the fish would die.
