The purpose of this study was to assess of some hematological parameters of Esox lucius collected from Anzali wetland from fall 2010 to summer 2011. Variations in hematological parameters such as hematocrit (Ht), hemoglobin concentration (Hb), erythrocyte (RBC) and leukocyte (WBC) counts, mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC), lymphocytes, monocytes, neutrophils, and eosinophils of fish were compared according to age and seasonal differences. Analysis of variance showed significant differences in values of white blood cell (WBC), red blood cell (RBC), MCV, MCH, lymphocytes, monocytes, and eosinophils between ages. Statistical analysis revealed significant differences in RBC and WBC between all seasons. However, there were no significant differences in Ht, Hb, MCHC, MCH, MCV, neutrophils, lymphocytes, monocytes, and eosinophils between all seasons. Results of current study may be helpful in establishing a hematological data bank for this species including standard values of blood parameters.
