Determination of some hematological and biochemical parameters at different ages of reared Persian sturgeon (Acipenser persicus)

The analysis of blood parameters is a useful indicator in assessing the physiological conditions of aquatic animals in response to stress, pollutants, nutrition, and also physiological and ecological changes. In this study, some hematological parameters of Acipenser persicus in three age classes including cultured fingerlings, juveniles and broodstocks were studied in a six-month period (spring and summer 2012). The counts of red blood cells (RBC), white blood cells (WBC), hematocrit (PCV), hemoglobin (Hb), MCV, MCH, MCHC, electrolyte and non-electrolyte biochemical parameters, and also differential leucocyte count were measured in different age classes. For this reason, 30 Persian sturgeon(10 fingerlings, 10 juveniles, 5 males and 5 females) were used. Statistical results showed significant differences in Hb, RBC, MCV, MCHC, WBC, lymphocyte (%), neutrophil (%) and eosinophil (%) in different age classes of this species (P
