• 摘要： 本實驗研究了不同濃度MS-222對細鱗魚幼魚的麻醉效果。結果表明：細鱗魚幼魚的麻醉過程可分為不被麻醉、輕度麻醉、中度麻醉和深度麻醉；在不同濃度MS-222條件下，細鱗魚幼魚進入不同麻醉程度的時間有差異；在30 mg/l濃度下，MS-222處理 900 s，細鱗魚幼魚100%呈現輕度麻醉；在35 mg/l濃度下，301.5 s幼魚全部進入輕度麻醉，567 s呈現中度麻醉；在40 mg/l濃度下，57.5 s幼魚全部進入輕度麻醉，638.5 s呈現深度麻醉；在45 mg/l，120 s幼魚直接進入中度麻醉，528.5 s呈現深度麻醉；在45 mg/l~55 mg/l濃度范圍，幼魚100%呈現深度麻醉的情況，且麻醉時間逐漸縮短。濃度超過45 mg/l，麻醉時間超過12 h，細鱗魚幼魚出現了死亡，因此使用麻醉劑MS-222需要注意濃度和使用時間。
• The anesthetic effect of different concentrations of MS-222 on Brachymystax lenok Pallas was observed. The results showed that the anesthetic effect of juvenile fish was a gradual process, which can be divided into four groups: non-anaesthesia, light anesthesia, moderate anesthesia and deep anesthesia. There were differences in the time of entering different anaesthesia degree at different concentration of MS-222. In the process of 900 s treated with MS-222, 100% of juvenile fish showed light anaesthesia under the concentration of 30 mg/l. At 301.5 s, juvenile fish all entered mild anesthesia during the concentration of 35 mg/l, 567 s showed moderate anesthesia. At 57.5 s, juvenile fish all entered mild anesthesia during the concentration of 40 mg/l, 638.5 s showed deep anesthesia. During the experiment, 100% of 45 mg/l ~ 55 mg/l showed deep anesthesia, and the duration of all anesthesia was shortened gradually. When the concentration exceeded 45 mg/l, and the anesthesia time exceeded 12 hours, the juvenile fish died. Therefore, attention should be paid to the concentration and time of the anesthetic MS-222.
