摘　　要：研究了MS-222、丁香酚2种麻醉剂对人工繁养刀鲚(Coilia nasus Schlegel)幼鱼的麻醉效果,探索了2种麻醉剂在安全浓度下麻醉后刀鲚幼鱼暴露在空气中的时间,并运用该2种麻醉剂的适宜剂量对刀鲚幼鱼进行了运输实验。麻醉实验表明:(1)理想MS-222浓度为150 mg/L,理想丁香酚麻醉剂浓度为30 mg/L;(2)经MS-222浓度为150 mg/L深度麻醉后,适宜的暴露在空气中的时间应<4 min;经丁香酚浓度为30 mg/L深度麻醉后,适宜的在空气中的时间应<5 min;(3)养殖长江刀鲚幼鱼采用30 mg/L MS-222和8 mg/L丁香酚分别麻醉后,其复苏率和48 h内的成活率均达到100%,与各自对照组存在明显差异(P<0.05)。The anesthetic effect of MS-222 and eugenol on Coilia nasus Schlegel juvenile fish was investigated. The exposure time in air of juvenile fish was determined under the safe concentrations of the two anesthetics. The transport test of young fish was conducted by using the suitable concentration of the two anesthetics. The results indicated：（ 1） The suitable concentrations of MS-222 and eugenol were 150 mg / L and 30 mg / L,respectively.（ 2） The suitable exposure time in air was below 4 min after the deep anesthesia at the MS-222 concentration of 150 mg / L,the suitable exposure time in air was below 5 min after the deep anesthesia at the eugenol concentration of 30 mg / L.（ 3） The recovery rate and survival rate of the cultural Coilia nasus Schlegel young fish were both 100% after treating with 30 mg / L MS-222 and 8 mg / L eugenol,respectively. There were significant differences between test group and the control both in MS-222 and eugenol,respectively（ P〈0. 05）.
