Eleginops maclovinus has been an important fishery resource in Chile since 1957. Caligus rogercresseyi is one of the most prevalent ectoparasite species found on E. maclovinus. Hematocrit, hemoglobin level, red blood cell count (RBC), white blood cell count (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and differential white blood cell count were determined before and after an experimental infestation with C. rogercresseyi. We found significant differences in the hemoglobin level, WBC, MCV, MCH, MCHC, hematocrit level and RBC between infested and uninfested fish. Furthermore correlations between number of C. rogercresseyi with hematocrit, MCHC, neutrophil, eosinophil and lymphocyte counts were found. Hematological reference ranges of E. maclovinus in captivity conditions were also established.
自1957年以来，麦氏智利鲈一直是智利重要的渔业资源。罗氏海盘虫是在麦氏智利鲈身上发现的最常见的外寄生虫物种之一。在罗氏海盘虫实验性感染前后，测定了血细胞比容、血红蛋白水平、红细胞计数（RBC）、白细胞计数（WBC）、平均红细胞体积（MCV）、平均红细胞血红蛋白含量（MCH）、平均红细胞血红蛋白浓度（MCHC）和白细胞分类计数。我们发现，受感染和未受感染的鱼在血红蛋白水平、白细胞、平均红细胞体积、平均红细胞血红蛋白含量、平均红细胞血红蛋白浓度、血细胞比容水平和红细胞计数方面存在显著差异。此外，还发现罗氏海盘虫数量与血细胞比容、平均红细胞血红蛋白浓度、中性粒细胞、嗜酸性粒细胞和淋巴细胞计数之间存在相关性。还建立了圈养条件下麦氏智利鲈的血液学参考范围。
