Study of blood and serum parameters of golden gray mullet (Liza aurata) in Caspian Sea

Study of bloodand serum parameters is considered as a method for evaluating of physiological state of animals including fishes. Hematological properties of different species of fish can be used as an important indicator for ichthyology.The aim of this study was evaluation of some blood and serum parameters of golden gray mullet (Liza aurata) in Caspian Sea. Bloodparameters including the number of red blood cells (RBC), number of white blood cell (WBC), hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and serum parameters including total protein (TP), glucose (GL), cholestrol (CHOL), alkaline phosphatase(ALP), aspartate aminotransferase (AST), and Alanin aminotransferase (ALT) were measured. The results of this study showed no significant effect of height and weight of the studied fishes on blood and serum parameters.Therefore, there were no significant differences between blood and serum parameters of the golden gray mullet in two studied weights.Blood and serum parameters can displayevident sign of physiological or pathological status in fishes and desirable or undesirable environmental conditions, so regular monitoring of blood and serum parameters can provide valuable information.
