3种麻醉剂对哲罗亲鱼麻醉效果的比较

A Comparative Study of the Anesthetic Effects of Three Anesthetics on Taimen( Hucho taimen,Pallas)

为寻找哲罗（Hucho taimen,Pallas）亲鱼在标志、催产注射、挤卵（精）时安全与有效的麻醉方法,本试验比较了三氯叔丁醇、丁香油和苯氧乙醇3种麻醉剂对哲罗亲鱼的麻醉效果。试验结果显示：（1）三氯叔丁醇,入麻时间和恢复时间均较长,可达到深度麻醉期;丁香油,入麻时间短,不能达到深度麻醉期,触觉恢复快,完全恢复所需时间较长;苯氧乙醇,入麻时间短,恢复也快,可达到深度麻醉期。（2）3种不同质量分数（0.1‰,0.3‰,0.5‰）的苯氧乙醇麻醉亲鱼的恢复时间y（s）与暴露时间x（s）之间可用线性方程表示,依次为：y1=24.5x＋65.9,（R2=0.990 3,60≤x≤300）;y3=26.5x＋82.3,（R2=0.976 1,60≤x≤300）;y5=55.5x＋176.0,（R2=0.999 8,60≤x≤300）。试验结果表明,在本实验中,苯氧乙醇是哲罗亲鱼进行标记、催产注射、挤卵（精）等操作的合适麻醉剂,其安全效用范围为0.1‰~0.3‰,建议最佳剂量质量分数为0.3‰。

The current study aimed to find the best anesthetic for electronic chip markers,injection of exogenous hormones,squeezing eggs（ semen） of taimen（ Hucho taime）（ parent fish）. The anesthetic effects of chlorobutanol,clove oil,2-phenoxyethanol on taimen（ parent fish） were compared. The results showed that,（ 1）chlorobutanol： anesthetizing time and recovery time were longer,and up to the depth of anesthesia; Clove oil： anesthetizing time was short,did not achieve the depth of anesthesia,tactile recovery was quick,but complete recovery time was longer; 2-phenoxyethanol： anesthetizing time and recovery time were shorter,and up to the depth of anesthesia.（ 2） The linear equations of the exposure time and the recovery time with different concentrations（ 0.1‰,0.3‰,0.5‰） of 2-phenoxyethanol were respectively： y1= 24. 5x ＋ 65. 9,（ R2= 0. 990 3,60≤x≤300）; y3=26. 5x ＋ 82. 3,（ R2= 0. 976 1,60≤x≤300）; y5= 55. 5x ＋ 176. 0,（ R2= 0. 999 8,60≤x≤300）. The results indicated that 2- phenoxyethanol was the best anesthetic for electronic chip markers,injection of exogenous hormones,squeezing eggs（ semen）,and its security utility range was 0. 1‰- 0. 3‰,the optimal dose concentration was 0. 3‰.
