The aim of this study was to obtain a basic knowledge of the hematology of Schizothorax (Racoma) davidi (Sauvage). The results showed that red blood cell and white blood cell counts as well as mean cellular hemoglobin concentration were significantly higher in females than in males, while mean cell volumes were significantly lower in females than in males. No significant differences were seen in other hematological parameters in relation with gender. Under light microscope, erythrocytes (mature and immature), leukocytes (neutrophils, lymphocytes, and monocytes), and thrombocytes were distinguished. Mature erythrocytes were ellipsoidal cells with oval, central nucleus. Neutrophils contained banded or segmented nuclei. Small lymphocytes had a very thin rim of basophilic cytoplasm. Monocytes often possessed vacuoles in their cytoplasm. Thrombocytes existed in several forms with relatively large nucleus surrounded by a pink‐stained or hyaline cytoplasm. The percentage of the different leukocytes revealed predominance of neutrophils and small lymphocytes, followed by monocytes and large lymphocytes. The neutrophil percentages of each stage showed that metamyelocyte accounted for the most, followed by banded neutrophils. This investigation could be used for evaluation of the health status of cultured male and female S. davidi and will provide early detection of clinical pathology.
