The aim of this study was to investigate sex hormones, ionic, lipid metabolism, and hematological indices in female sea carp and farmed sea carp brood stock. Forty female carp brood stock (20 marine and 20 farmed marine) were age-determined. To compare sex hormonal and biochemical factors, blood samples at the time of ovulation were collected from 20 wild (S3 and S4, respectively) and farmed sea carp (C3 and C4, respectively) brood stock with 3 and 4 years old, and divided into two parts. In the present study, the concentrations of steroid hormones had a statistically significant difference between the experimental groups. The highest concentrations of testosterone, 17beta-estradiol, progesterone, and the lowest concentrations of vetilogenin hormone were found in the blood serum of cultured marine broodstock (C3 and C4). The concentration of ions was statistically significantly different between the experimental groups, with the highest concentrations of sodium and magnesium ions and the lowest concentrations of calcium, alkaline phosphatase, and protein were found in the blood serum of female sea carp broodstock (S3 and S4). Triglyceride, cholesterol and LDL concentrations decreased and HDL increased significantly in marine broodstock. The results of statistical analysis showed that the highest number of red blood cells, hemoglobin, hematocrit, neutrophils, and monocytes were observed in the blood of cultured marine brood stock (especially in group C3). In general, the results showed that in the female brood stock, the sex hormones status, Ion concentration, and lipid metabolism was not affected by age, but the factor of the brood stock habitat (marine or farmed) had a statistically significant effect on the reproduction physiological factors.
