Russian or Danube sturgeon (Acipenser gueldenstaedtii) are an important, critically endangered roe-producing species. Despite a wealth of knowledge pertaining to other members of Acipenseridae there is very limited published information regarding baseline blood analytes in Russian sturgeon. The objectives of this study were 1) to establish reference intervals for a suite of hematological and biochemical data and 2) to compare plasma chemistry data to two point-of-care (POC) cartridges, tested on the VetScan iSTAT® 1 analyzer, that use heparinized whole blood for the assessment of clinically normal, aquacultured adult Russian sturgeon sedated with eugenol (Aqui-S® 20E) at a single institution. Reference intervals are reported. The calculated hematocrit measured by the POC analyzer tended 4-5% lower than the spun packed cell volume (PCV), confirming the importance of spun PCV as a reliable measurement of red blood cell mass. Various analytes, notably whole blood urea nitrogen, glucose, sodium, total carbon dioxide, chloride, ionized calcium, and anion gap, were significantly different by both POC cartridges. This study successfully produced reference intervals for blood analytes in adult Russian sturgeon under managed care and creates a foundation for future studies into the effects of extrinsic and intrinsic factors, and into variations of analytical methodologies on blood analytes in this species.

成年水族馆饲养的俄罗斯鲟 (Acipenser gueldenstaedtii) 血液分析物的参考区间

俄罗斯或多瑙河鲟 (Acipenser gueldenstaedtii) 是一种重要的、极度濒危的产卵鱼种。尽管与 Acipenseridae 的其他成员有关的知识丰富，但关于俄罗斯鲟鱼的基线血液分析物的公开信息非常有限。本研究的目的是 1) 为一套血液学和生化数据建立参考区间，以及 2) 将血浆化学数据与在 VetScan iSTAT® 1 分析仪上测试的两个即时 (POC) 试剂盒进行比较，即在单一机构使用肝素化全血评估临床正常的水产养殖成年俄罗斯鲟，丁香酚 (Aqui-S® 20E) 镇静。报告了参考区间。由 POC 分析仪测量的计算血细胞比容比旋转压实细胞体积 (PCV) 低 4-5%，证实了旋转 PCV 作为红细胞质量的可靠测量的重要性。两种 POC 小柱的各种分析物，特别是全血尿素氮、葡萄糖、钠、总二氧化碳、氯化物、离子钙和阴离子间隙都有显着差异。该研究成功地为受管理的俄罗斯成年鲟的血液分析物提供了参考区间，并为未来研究外在和内在因素的影响以及对该物种血液分析物的分析方法的变化奠定了基础。
