摘　　要：秦岭细鳞鲑属国家二级保护水生野生动物。为研究间氨基苯甲酸乙酯甲磺酸盐(MS-222)在秦岭细鳞鲑的人工繁育、标记放流和运输环节中使用剂量和麻醉效果,分别以体重为9.8±5.2g和160±5.2g的秦岭细鳞鲑苗种和成鱼为试验对象,探索麻醉剂使用的最适浓度。结果表明,在秦岭细鳞鲑人工繁育和人工标记中以浓度为45mg/L的MS-222为最佳,而放流前麻醉运输的最适麻醉浓度为10mg/L。麻醉剂MS-222的可用浓度范围为0~50mg/L,随着MS-222浓度的增加,进入相同麻醉期的时间缩短,完全复苏的时间延长,成鱼的麻醉时间比苗种麻醉所需时间长。MS-222麻醉秦岭细鳞鲑效果好,鱼体麻醉时间短,苏醒快,安全性高。Brachymystax lenok tsinlingensis is the second class protected aquatic wild animal in China. During the process of artificial breeding, markers and transportation, the additive dose and anesthetic effect of MS-222 on Brachymystax Lenok tsinlingensis were studied in this paper. The additive doses of MS-222 were studied using fish fries and adult fish of Brachymystax lenok tsinlingensis with average weight of 9.8 g±5.2 g and 160 g±5.2 g, respectively. The result showed that 45 mg/L MS-222 was suitable for artificial breeding and manual mark, and 10 mg/L MS-222 had better anesthetic effect than other experiment group doses in transportation. The result showed that the range of effective concentrations of MS-222 was 0-50 mg/L. With the gradual incensement of MS-222, the needing time that experiment fish have the same anesthetic period was shortened, but the absolute recovery time was prolonged. The anesthetic time of adult fish is longer than that of fish fries. The results are important for survival rate of Brachymystax lenok tsinligensis.
