AbstractIn this study, monthly changes of blood protein levels in rainbow trout were examined. For this purpose, fish samples were obtained from cages established on Keban Dam Lake (Elazığ). This study was carried out for one year and 10 fish with same age group were examined monthly. Firstly, total length and live weight of fish samples were measured and then blood samples were taken from caudal vein. Serum in blood samples were separated and total protein, albumin, globulin and fibrinogen levels in blood serum were determined. In the examined blood samples, the highest values were found as 4.52 g/dL for total protein, 2.37 g/dL for albumin, 2.15 g/dL for globulin in March and 198.74 mg/dL for fıbrinogen in January. On the other hand, the lowest values were obtained in the winter season for total protein, albumin and globulin, and in the summer season for fibrinogen. According to the statistical analysis, it was found that monthly changes of all determined values was significant. In addition, the changes of albumin, globulin and fibrinogen levels with the length and weight of fish were also found positive relationship. Monthly changes of all these values were statistically found significant.
