MS-222对两种规格的异齿裂腹鱼麻醉效果研究

ANESTHETIC EFFECTS OF MS-222 ON SCHIZOTHORAX O’CONNORI LLORD IN TWO SIZE RANGES

  • 摘要: 通过MS-222对2种规格的异齿裂腹鱼进行麻醉行为特征研究, 为高原鱼类的麻醉以及运输提供技术支持。试验表明: MS-222麻醉大规格(25.0±1.5) cm和小规格(14.8±2.3) cm异齿裂腹鱼时, 在麻醉时期3期以内, 呼吸频率增加并之间无显著性差异, 在麻醉4期以后呼吸频率才开始显著下降。MS-222麻醉大规格和小规格异齿裂腹鱼的有效质量浓度分别为150—180 mg/L和150 mg/L。在此浓度范围内, 大规格异齿裂腹鱼在MS-222麻醉液中, 5min之内达到4级麻醉状态, 5min之内苏醒恢复, 且在麻醉液中浸浴20min后成活率为100%时的浓度; 小规格异齿裂腹鱼在MS-222麻醉液中, 5min之内达到4级麻醉状态, 7min之内苏醒恢复, 且在麻醉液中浸浴20min后成活率为100%时的浓度。大规格异齿裂腹鱼在180 mg/L的MS-222溶液中麻醉5min, 在空气中进行暴露0—15min, 复苏时间无显著性差异(P>0.05); 小规格异齿裂腹鱼在150 mg/L的MS-222溶液中麻醉5min, 在空气中进行暴露0—15min, 复苏时间存在显著性差异(P<0.05)。

     

    Abstract: This study examined anesthetic behaviors of Schizothorax o’connori Llord in two size ranges as induced by MS-222, to acquire useful information on anesthesia of said highland fish species in out-of-water activities (surgery, labeling, measurement, etc.). Test results indicated that for both large (25.0±1.5) cm and small-sized (14.8±2.3) cm specimens, respiration rates showed no significant change in anesthetic stages Ⅰ to Ⅲ, and only begun to significantly decline after entering stage Ⅳ. The effective concentrations of MS-222 were 150—180 mg/L and 150 mg/L for two sizes, respectively. The 150—180 mg/L caused large specimens to enter anesthetic stage Ⅳ within 5min, and recovered within 5min; the 150 mg/L caused small specimens to enter stage Ⅳ within 5min, and recovered within 7min; both doses ensured a 100% survival rate after immersion for 20min. For large specimens anesthetized at 180 mg/L for 5min and exposed to air for 0—15min, there was no significant difference in recovery times (P>0.05); for small specimens anesthetized at 150 mg/L for 5min and exposed to air for 0—15min, there were significant differences in recovery (P<0.05).
