The transportation of rainbow trout in the presence of the anesthetic clove oil was investigated. Before the transportation tests, an acute experiment was conducted to verify that removal of the fish from the water for one minute does not significantly increase the glucose or cortisol concentration of the blood plasma. In the main experiment two different transportation conditions were compared: transport in water only and in water with anesthetic. During transportation without addition of clove oil, blood plasma glucose and cortisol concentrations changed significantly. The concentration of glucose increased from 4.92 mmol/L prior to transportation to 6.16 mmol/L and values similar to the initial ones (4.95 mmol/L) were observed 5 hours after transportation. Concentration of the stress hormone cortisol increased from the initial 37.2 ng/mL to 89.2 ng/mL and returned to a value of 36.1 ng/mL 3 hours post transportation. Respective values of glucose concentration have not changed significantly during transportation in the presence of clove oil (4.3; 4.4; 4.4 mmol/L), whereas those of cortisol showed a slight decrease with the passing of time (28.1; 26.7; 20.18 ng/mL). Results show that transportation stress can significantly be reduced by the use of anesthetics.
研究了在麻醉剂丁香油存在的情况下虹鳟鱼的运输情况。在运输试验之前,进行了一项急性实验,以验证将鱼从水中取出一分钟不会显著增加血浆中的葡萄糖或皮质醇浓度。在主要实验中,比较了两种不同的运输条件:仅在水中运输和在含麻醉剂的水中运输。在不添加丁香油的运输过程中,血浆葡萄糖和皮质醇浓度发生了显著变化。葡萄糖浓度从运输前的4.92 mmol/L增加到6.16 mmol/L,运输5小时后观察到的值与初始值(4.95 mmol/L)相似。应激激素皮质醇的浓度从初始的37.2 ng/mL增加到89.2 ng/mL,并在运输后3小时恢复到36.1 ng/mL。在丁香油存在的运输过程中,葡萄糖浓度的相应值没有显著变化(4.3;4.4;4.4 mmol/L),而皮质醇的值随着时间的推移略有下降(28.1;26.7;20.18 ng/mL)。结果表明,使用麻醉剂可以显著降低运输应激。
