The aim of this work was to determine the impact of etomidate (Propiscin) dose (1 and 2 ml l) and exposure time (2 and 10 min) on the biochemical and haematological parameters of juvenile pikeperch (Sander lucioperca) [mean body length (Lc) 25.9 cm; body weight (W) 189.9 g] that were reared in a recirculating aquaculture system (RAS). Significant changes in the mean values of total protein, globulin, calcium, magnesium, and ammonia were noted in all groups immediately following exposure. The greatest changes in the haematological indicators were observed in groups subjected to 10-min exposure at both doses of the anaesthetic. The specimens from these groups had higher values for white blood cells (WBC), red blood cells (RBC), haemoglobin (HGB), haematocrit (HCT), and mean corpuscular volume (MCV). Statistically significant differences in these same parameters were also noted in the groups of fish exposed to the anaesthetic for 2 min at a dose of 2 ml l, but they were not as pronounced. Twenty-four h following exposure to etomidate, all blood parameters in the experimental groups were comparable to those of the control group. Etomidate can be recommended as a safe, effective anaesthetic for pikeperch.
本研究旨在确定依托咪酯（Propiscin）剂量（1毫升/升和2毫升/升）和暴露时间（2分钟和10分钟）对循环水养殖系统（RAS）中养殖的幼龄梭鲈（Sander lucioperca）[平均体长（Lc）25.9厘米；体重（W）189.9克]生化和血液学参数的影响。暴露后立即观察到所有组的总蛋白、球蛋白、钙、镁和氨的平均值均有显著变化。在两种麻醉剂剂量下暴露10分钟的组中，血液学指标变化最大。这些组的样本白细胞（WBC）、红细胞（RBC）、血红蛋白（HGB）、血细胞比容（HCT）和平均红细胞体积（MCV）值较高。在以2毫升/升剂量暴露2分钟的鱼组中，这些相同参数也存在统计学显著差异，但不那么明显。暴露于依托咪酯24小时后，实验组的所有血液参数与对照组相当。依托咪酯可被推荐为梭鲈安全、有效的麻醉剂。
