In recent years, common carp cultivation has been proposed for cage culture in the Caspian Sea during the warm seasons, but there is no data available on the effects of water salinity on the physiology of this fish, especially at low weights. Therefore, the present study aimed to investigate the effects of different salinity of water on hematological parameters, including red blood cell count (RBC), hemoglobin concentration (Hb), hematocrit percentage (Hct), mean corpuscular hemoglobin (MCH), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), white blood cell count (WBC), and and differential count of white blood cell in this fish with an average weight of 5.53±0.57 g were designed. In this experiment, four treatments, including 5, 13, 20 and 30 ppt and fresh water (as a control) were considered for 8 weeks. The results showed that with increasing water salinity, the amount of all studied hematological factors changes significantly (p < /em><0.05). However, changes in the hemoglobin in different treatments were not statistically significant (p < /em>>0.05). The results of differential white blood cell count showed a significant increase in neutrophils and monocytes due increasing water salinity (p < /em><0.05).
