Blood parameters regarded as valuable tools for monitoring fish health and growth is influenced by many intrinsic and extrinsic factors. In this study that aimed to evaluate the effect environmental and intrinsic factors on hematological parameters of Alburnus chalcoides,84 fish samples (average body weight 45.69±27.10 gr and average body length 16.50±3.98 cm) were collected from three sampling stations (sea, river, and estuary) in the southern coast of the Caspian Sea in Gilan Province during 12 months. Biometry and determination of sex, blood samples were collected from the caudal peduncle and used for hematological studies. Red blood cell count (RBC), hemoglobin (HGB), and hematocrit (HCT) values were significantly in males higher than in females (P<0.05). These hematological parameters were significantly higher in the river than in the sea and estuary and in the summer than other seasons (P<0.05). In Pearson correlation test, blood factors had significant negative correlation with water salinity and total length as well as weight of fish. They also had significant positive correlation with water temperature (P<0.01). Regression analysis showed a significant relationship between blood factors and water temperature (P<0.01).
