ANESTHETIC EFFECTS OF MS-222 ON SCHIZOTHORAX O'CONNORI LLORD IN TWO SIZE RANGES
摘要
Abstract
This study examined anesthetic behaviors ofSchizothorax 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 Ⅰto 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).关键词
