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.
