In this study, seasonal changes in some blood parameters related to oxygen transport in adult tilapia (Oreochromis niloticus L.) were detected. Blood samples were collected from caudal vein of each fish. Red blood cell (RBC), mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration(MCHC), hematocrit (Hct), methemoglobin (Hi), serum iron concentration (SI), total iron binding capacity (TIBC), unsaturated iron binding capacity (UIBC), serum transferrin (TRF), transferrin saturation (TRF %) levels were determined. RBC, length and weight of fish were found to be linear relation. It was found that there were linear relations between SI, RBC, Hct, Hb, TIBC, UIBC, TRF and %TRF. Negative relation was found between oxygen level in the water RBC, Hb, MCH, SI, TIBC, UIBC, TRF and %TRF parameters. There is a linear relation among MCH, MCHC and Hi levels, which is statistically insignificant (P>0.05). Negative correlation was found between Hi and other parameters, which are detected. But Hi was found to be differ significantly when compared with SI, TIBC, UIBC, TRF and %TRF by statistical analysis (P>0.05). The data obtained indicated that all parameters were found to be effected significantly by the seasonal changes (P<0.05). In addition, these parameters were determined to be lower in autumn and winter than in spring and summer. However, blood parameters of all the fish tested were detected within the normal values.
