人工养殖的家鱼与野生鱼,虽系同种,因其营养情况不同,两者的血液中的化学性貭,便有所不同。一般说来,两者血液中的红血球数目与血红素含量是差不多的,但其血糖含量却有很大的差别。野生鱼较活泼而运动量较高,其血糖含量就较高。到了冬天,鳗、鲤呈饥饿状态,鲤鱼中血清蛋白、红血球、血红素等含量锐减;鳗鱼经长时间饥饿之后,血糖和血液中的尿素也显著地减少,而血清钙和肌酸酐也相应地降低。因为鱼在营养不良状态之下,其造血机能受到障碍 Artificially cultivated domestic fish and wild fish, though of the same species, differ in their nutritional status due to their different nutritional status. In general, the number of red blood cells in the blood is similar to that of heme, but the blood sugar level is quite different. Wild fish more lively and exercise higher, the blood sugar content is higher. In the winter, eel, carp was starved, carp serum protein, red blood cells, heme and other content dropped sharply; eel long after starvation, blood glucose and blood urea also significantly reduced serum calcium and creatinine corresponding Lower ground. Because the fish is under malnutrition, its hematopoietic function is hampered
