Aims Hematological and biochemical parameters are valuable indicators for monitoring fish health and physiological responses, nutritional status and environmental conditions affecting fish health. In this study, the comparison of hematological indices and some biochemical and hormonal factors of blood serum in male and female sea carp were investigated.
Materials and Methods For this purpose, blood samples were taken from two groups of male and female broodstock with 14 fish from each group.
Findings The results of this study on hematological factors showed that in terms of  red blood cell (RBC), hematocrit (HCT), hemoglobin (HB), mean red blood cell volume (MCV), mean concentration of hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), white blood cell (WBC), monocyte (Mo) and granulocyte (Gr), there is no statistically significant difference between the two sexes (P> 0.05). The results of this study showed that there was a statistically significant difference between males and females in terms of glucose, cholesterol, calcium and cortisol (P <0.05). The amount of glucose and cholesterol in males and the amount of calcium and cortisol in females were higher. There is no statistically significant difference between males and females in terms of triglyceride, total protein, albumin, sodium and potassium (P> 0.05).
Conclusion The results of this study show that sex in sea carp during maturity has no effect on the hematological parameters of fish but can affect some biochemical factors in the blood serum of carp such as glucose, cholesterol, calcium and cortisol.
