Description
In this study, biochemical parameters in the blood serum of the common carp were investigated. To establish baseline blood serumbiochemistry values, blood sampleswere collected from ten common carp per season for three seasons (autumn, winter, and spring). The results showed that protein, cholesterol, and 17â-estradiol increased significantly (p<0.05) during the experimental period from autumn to spring. Total lipid, triglyceride, and 17á-hydroxyprogesterone indicated no significant differences during the three seasons (p>0.05). A Pearson analysis revealed that there was no significant correlation between the studied parameters except for protein and cholesterol. The mean contents of protein, total lipid, triglyceride, cholesterol, 17â-estradiol, and 17á- hydroxyprogesterone obtained were 3.29 g/dl, 615.7 mg/dl, 101.1 mg/dl, 162.9 mg/dl, 46.6 ng/ml, and 0.67 ng/ml, respectively. GSI measurements increased from autumn to spring. Histological measurements detected ovary progression of the common carp from sexual stage III to V, during autumn to spring. These results suggest that sexual maturation can affect biochemical variations of fish blood serum.
