This study was designed to investigate any seasonal (spring, summer, autumn and winter) changes in haematological parameters in the blood of Tinca tinca measuring the number of red blood cells (RBC), haematocrit, white blood cells, and total plasma proteins. The results show significant changes in RBC and haematocrit in males comparing spring and summer with autumn and winter, whereas in females the RBC remained constant for all 4 seasons but the haematocrit decreased in autumn and winter compared to spring and summer. The white blood cells of male and female animals were significantly lower in spring and winter compared to summer and autumn. In male fish total protein contents significantly decreased in autumn and winter compared to spring and summer, whereas in females protein output significantly decreased in winter compared to the other seasons. The results indicate marked seasonal variation in the blood of male and female Tinca tinca. This variation may play a important protective role for the survival of the animals.
本研究旨在通过测量丁鱥血液中的红细胞数量、血细胞比容、白细胞和总血浆蛋白，调查丁鱥血液学参数的任何季节性（春、夏、秋、冬）变化。结果显示，雄性丁鱥在比较春季和夏季与秋季和冬季时，红细胞和血细胞比容有显著变化，而雌性丁鱥的红细胞在所有四个季节中保持恒定，但与春季和夏季相比，秋季和冬季的血细胞比容下降。与夏季和秋季相比，雄性和雌性动物的白细胞在春季和冬季显著降低。雄性鱼类的总蛋白含量在秋季和冬季与春季和夏季相比显著下降，而雌性鱼类的蛋白质产量在冬季与其他季节相比显著下降。结果表明，雄性和雌性丁鱥的血液存在明显的季节性变化。这种变化可能对动物的生存起到重要的保护作用。
