Blood biochemical profile can be used to evaluate the health status of fish and ambient environmental conditions. However, it is not well known in the aquaponic systems, let alone their differences between hydroponic and aquatic plants. A 5-month trial was conducted to investigate the changes in the growth performance and blood index of Qihe crucian carp Carassius auratus in eight aquaponic systems (control, Ipomoea aquatica, Lactuca sativa, Lemna minor, Amaranthus tricolor, Ceratophyllum demersum, Vallisneria spiralis, and C. demersum-net, indicated by CK, Ia, Ls, Lm, At, Cd, Vn, and Cd-ns). Results showed that weight gain rate and specific growth rate did not significantly differ among the eight groups. However, most blood parameters significantly differed among the eight groups. The glucose level and activities of alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase were generally larger in Cd, Lm, Vn, and CK groups, and smaller in Ia, Ls, or At groups. Additionally, the triglyceride, cholesterol, albumin, and albumin/globulin were mostly elevated in Ia and At groups. Moreover, the creatinine, total proteins, and globulin levels peaked in Vn group. These findings showed that the blood biochemical profile was more sensitive than the growth performances and that hydroponic plants can induce a higher production and more healthy status of Qihe crucian carp C. auratus when compared with aquatic plants or no plants.
血液生化指标可用于评估鱼类的健康状况和环境条件。然而，在水培系统中，这方面的知识并不普及，更不用说水生植物和水培植物之间的差异了。本研究进行了为期 5 个月的试验，以研究 8 种水培系统（对照、空心菜、生菜、浮萍、苋菜、金鱼藻、水盾草和金鱼藻网，分别用 CK、Ia、Ls、Lm、At、Cd、Vn 和 Cd-ns 表示）中淇河鲫鱼 Carassius auratus 的生长性能和血液指标的变化。结果表明，8 组的增重率和特定生长率没有显著差异。然而，8 组的大多数血液参数有显著差异。葡萄糖水平以及碱性磷酸酶、丙氨酸转氨酶和天冬氨酸转氨酶的活性在 Cd、Lm、Vn 和 CK 组中通常较大，而在 Ia、Ls 或 At 组中较小。此外，Ia 和 At 组的甘油三酯、胆固醇、白蛋白和白蛋白/球蛋白大多升高。此外，Vn 组的肌酐、总蛋白和球蛋白水平达到峰值。这些发现表明，与生长性能相比，血液生化指标更为敏感，与水生植物或无植物相比，水培植物可以提高淇河鲫鱼 C. auratus 的产量和更健康的状态。
