The hematological properties and the oxygen-transport system of the antarctic fish Pleuragramma antarcticum were investigated. Most blood parameters are at the lower end of the range of values known for red-blooded antarctic fish, suggesting a link with the sluggish mode of life of this species. P. antarcticum is the only species of the family Nototheniidae and of the suborder Notothenioidei having three major hemoglobins, which were isolated and fully characterized. The complete amino acid sequence of the alpha- and beta-globin chains was determined. The three hemoglobins showed strong Bohr and Root effects, and their oxygen-binding properties were differently regulated by temperature. None of the three hemoglobins of P. antarcticum can be considered as evolutionary (or larval) remnants. Therefore, this oxygen-transport system is one of the most specialized ever found in fish. The data suggest a strong relationship between hematological/biochemical adaptation and life style.
对南极鱼类南极冰鱼（Pleuragramma antarcticum）的血液学特性和氧运输系统进行了研究。大多数血液参数处于已知的红色血液南极鱼类数值范围的下限，这表明该物种的生活方式较为迟缓。南极冰鱼是南极鱼科和南极鱼亚目中唯一具有三种主要血红蛋白的物种，这些血红蛋白已被分离并进行了全面表征。确定了α-和β-珠蛋白链的完整氨基酸序列。这三种血红蛋白表现出强烈的玻尔效应和鲁特效应，并且它们的氧结合特性受温度的调节方式不同。南极冰鱼的三种血红蛋白都不能被视为进化（或幼虫）残余物。因此，这种氧运输系统是鱼类中发现的最特殊的系统之一。数据表明血液学/生化适应与生活方式之间存在密切关系。
