This study describes the hematological parameters in Iranocichla hormuzensis, an Iranian freshwater cichlid important as ornamental and food fish. Forty fish were captured with seine net at Mehran river Hormozgan province, Iran. Blood was used to determine the total counts of red blood cells (RBC) and white blood cells (WBC), hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and morphometric data of erythrocytes. The Iranian fish showed lower RBC and WBC values than the other cichlids (Oreochromis niloticus, O. aureus, O. mossambicus, O. hybrid, Cichlasoma dimerus and Cichla monoculus). Hematocrit did not vary among the species, but MCV, MCH and MCHC in I. hormuzensis were higher than those for O. niloticus, O. aureus, O. hybrid, C. dimerus and C. monoculus. These differences may be related to different life habit of fish. This study suggests that I. hormuzensis is well acclimated to the environment being the first report for its hematology. It is also suggested high efficiency in oxygen transportation, and an efficient inflow of oxygen by the gills, indicating the welfare of fish on this environment.
本研究描述了伊朗淡水丽鱼科鱼类——霍尔木兹伊朗丽鱼（Iranocichla hormuzensis）的血液学参数，该鱼类作为观赏鱼和食用鱼具有重要价值。在伊朗霍尔木兹甘省的梅赫兰河，用围网捕获了40条鱼。采集血液用于测定红细胞（RBC）和白细胞（WBC）的总数、血细胞比容、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）以及红细胞的形态学数据。伊朗的这种鱼的红细胞和白细胞值低于其他丽鱼科鱼类（尼罗罗非鱼、奥利亚罗非鱼、莫桑比克罗非鱼、杂交罗非鱼、双斑丽鲷和眼斑丽鲷）。各物种间血细胞比容无差异，但霍尔木兹伊朗丽鱼的平均红细胞体积、平均红细胞血红蛋白含量和平均红细胞血红蛋白浓度高于尼罗罗非鱼、奥利亚罗非鱼、杂交罗非鱼、双斑丽鲷和眼斑丽鲷。这些差异可能与鱼类不同的生活习性有关。本研究表明，霍尔木兹伊朗丽鱼对环境适应良好，这是其血液学的首次报告。研究还表明其在氧气运输方面效率较高，鳃对氧气的有效摄入，表明该鱼类在这种环境下的健康状况良好。
