This study aimed to find the relation of Sparus aurata (gilthead seabream) reproductive activities to some blood parameters as complete blood count, liver enzymes, some hormones related to reproduction process and microscopic findings of gonads, as well as expression of Bromodomain testis-specific gene. Eighty-eight sexually mature seabream were collected and investigated through the four seasons. Red blood cells were higher in autumn and spring. Hemoglobin was high in summer, MCV highest values ​​were seen in winter and summer, while MCHC was highest in summer. The values ​​of white blood cells increased significantly in spring, summer, and autumn compared with winter. The highest value of lymphocytes was recorded in spring and autumn. Eosinophil was recorded the highest value in the spring. The highest value of segmented neutrophils was recorded in summer. The highest value of band neutrophil was recorded in summer and winter. Alanine aminotransferase and aspartate aminotransferase showed high values in the winter. Luteinizing hormone (LH) was higher in females, males, and hermaphrodites during winter. Follicle-stimulating hormone (FSH) was higher in females during spring. The highest value of estradiol 17-β and progesterone was recorded in summer. The highest value of total testosterone was recorded in spring. Microscopically, ovaries were immature and inactive during spring and summer but well developed in autumn and winter. During spring and summer, testes were immature and began spermatogenesis process but well developed with the appearance of spermatids and spermatozoa during autumn and winter. The expression of Brdt was higher in testes than ovary. Brdt recorded high expression in autumn and spring than in summer and winter.

本研究旨在找出Sparus aurata (gilthead seabream) 生殖活动对一些血液参数的影响，如全血细胞计数、肝酶、一些与生殖过程相关的激素和性腺的显微发现，以及 Bromodomain 睾丸特异性基因的表达。通过四个季节收集和调查了 88 条性成熟的鲷鱼。秋季和春季红细胞较高。夏季血红蛋白偏高，冬季和夏季MCV最高，夏季MCHC最高。与冬季相比，春、夏、秋季白细胞值明显升高。淋巴细胞的最高值出现在春季和秋季。嗜酸性粒细胞在春季被记录为最高值。夏季记录了分段中性粒细胞的最高值。带状中性粒细胞的最高值出现在夏季和冬季。丙氨酸氨基转移酶和天冬氨酸氨基转移酶在冬季显示出较高的值。冬季，雌性、雄性和雌雄同体的黄体生成素 (LH) 较高。春季女性的促卵泡激素 (FSH) 较高。雌二醇 17-β 和孕酮的最高值记录在夏季。总睾酮的最高值记录在春季。显微镜下，卵巢在春季和夏季不成熟，不活跃，但在秋季和冬季发育良好。春夏两季睾丸发育不成熟，开始生精过程，秋冬季发育良好，出现精子细胞和精子。的表达 丙氨酸氨基转移酶和天冬氨酸氨基转移酶在冬季显示出较高的值。冬季，雌性、雄性和雌雄同体的黄体生成素 (LH) 较高。春季女性的促卵泡激素 (FSH) 较高。雌二醇 17-β 和孕酮的最高值记录在夏季。总睾酮的最高值记录在春季。显微镜下，卵巢在春季和夏季不成熟，不活跃，但在秋季和冬季发育良好。春夏两季睾丸发育不成熟，开始生精过程，秋冬季发育良好，出现精子细胞和精子。的表达 丙氨酸氨基转移酶和天冬氨酸氨基转移酶在冬季显示出较高的值。冬季，雌性、雄性和雌雄同体的黄体生成素 (LH) 较高。春季女性的促卵泡激素 (FSH) 较高。雌二醇 17-β 和孕酮的最高值记录在夏季。总睾酮的最高值记录在春季。显微镜下，卵巢在春季和夏季不成熟，不活跃，但在秋季和冬季发育良好。春夏两季睾丸发育不成熟，开始生精过程，秋冬季发育良好，出现精子细胞和精子。的表达 春季女性的促卵泡激素 (FSH) 较高。雌二醇 17-β 和孕酮的最高值记录在夏季。总睾酮的最高值记录在春季。显微镜下，卵巢在春季和夏季不成熟，不活跃，但在秋季和冬季发育良好。春夏两季睾丸发育不成熟，开始生精过程，秋冬季发育良好，出现精子细胞和精子。的表达 春季女性的促卵泡激素 (FSH) 较高。雌二醇 17-β 和孕酮的最高值记录在夏季。总睾酮的最高值记录在春季。显微镜下，卵巢在春季和夏季不成熟，不活跃，但在秋季和冬季发育良好。春夏两季睾丸发育不成熟，开始生精过程，秋冬季发育良好，出现精子细胞和精子。的表达 睾丸未成熟并开始精子发生过程，但发育良好，在秋冬季出现精子细胞和精子。的表达 睾丸未成熟并开始精子发生过程，但发育良好，在秋冬季出现精子细胞和精子。的表达睾丸中的Brdt高于卵巢。Brdt在秋季和春季的表达高于夏季和冬季。
