摘要: 旨在研究MS-222对大鳞鲃幼鱼的麻醉效果。在26±0.5℃的水温条件下,观测了大鳞鲃幼鱼在不同浓度MS-222处理下的麻醉效果,包括麻醉和复苏过程中的行为变化、麻醉过程中呼吸频率的变化以及不同空气暴露时间对麻醉幼鱼复苏时间、复苏率的影响。试验结果表明,大鳞鲃幼鱼的麻醉过程可分为6期,复苏过程分为4期。MS-222对大鳞鲃幼鱼的有效麻醉浓度范围为120~160mg/L。随着麻醉时间及浓度的加大,大鳞鲃幼鱼呼吸频率总体呈下降的趋势。进入5期麻醉的幼鱼,当空气暴露时间在4min以内时,复苏时间随空气暴露时间的增加而减少,当暴露时间在6min以上时,复苏时间随暴露时间的增加而增加,暴露10min以内均能复苏。实验证明,MS-222对大鳞鲃幼鱼有较好的麻醉效果,本实验可为大鳞鲃幼鱼的活体运输以及实验操作等提供理论支持。

Abstract: This study aims to investigate the anesthetic effect of MS- 222(Tric-ainemethanesulphonate) on juvenile Barbuscapito. At the temperature of (26±0.5)℃, the anesthetic effects of different concentrations of MS- 222 on juvenile Barbuscapito are observed, including behavior changes during anesthesia and resuscitation, and changes of respiratory frequency during anesthesia. At the same time, the effects of different air exposure times on recovery time and recovery rate of anesthetized juveniles are observed. The test results showed that the anesthetic process of juveniles of Barbuscapito was divided into 6 stages and the recovery process was divided into 4 stages. The effective anesthetic concentration of MS-222 for juvenile Barbuscapito was 120-160 mg/L. With the increase of anesthetic time and concentration, the respiratory rate of juvenile Barbuscapito showed a decreasing trend overall. For juvenile fish entering the 5th anesthetizing stage, when the air exposure time was within 4 min, the recovery time decreased with the increase of the air exposure time; when the exposure time was more than 6 min, the recovery time increased with the exposure time; none of the experiment fish died when exposed within 10 minutes. Experiments prove that MS-222 has good anesthetic effect on juvenile Barbuscapito.
