观测MS-222对大鲵(Andrias davidianus)的麻醉效果。12~15℃水温下,使用0.6 g/L MS-222对16尾4.7龄宁陕县东河的大鲵和16尾2.7龄周至县黑河的大鲵进行浸浴麻醉,每间隔5 min,观测个体的逃匿反应、翻正反射及痛感反应,记录个体麻醉时间和恢复时间并进行数据分析。使用0.6 g/L MS-222对大鲵进行浸浴处理,32尾个体均达到深度麻醉,所需时间为11~30 min,苏醒时间为30~180 min;体重与麻醉时间呈显著的正相关关系(r=0.320),水温与麻醉时间呈显著的强负相关关系(r=-0.698)。试验过程中没有个体死亡。
Observe the anesthetic effect of MS-222 on Andrias davidianus. Sixty-four 4.7-year-old Daphne fumigatus in Ningshan County and sixteen Dace-Macphersonaria in Heihe County of 2.7 weeks old were enrolled in the bath at a water temperature of 12-15 ℃ with 0.6 g / L MS-222 for 5 min. Escape response, righting reflex and pain response, record individual anesthesia time and recovery time and data analysis. The bathing time was 30 minutes and 180 minutes with the bathing time of 30 minutes, and the body weight was significantly correlated with the time of anesthesia (r = 0.320). There was a significant negative correlation between water temperature and anesthesia time (r = -0.698). No individual died during the experiment.
