| This study was done to find the effect of different levels of curcumin on growth performance, immune response, and hematological markers in Siberian sturgeon, Acipenser baerii. For this purpose, a total number of 120 Siberian sturgeons with an average initial weight of 55.05±0.03 g (means±SD) were distributed into 12 tanks with 10 fish per tank (4 treatments with 3 replications) and fed four diets supplemented with 0 (base group, (C0), 0.5 (C0.5), 1 (C1), and 1.5 (C1.5) g kg-1 curcumin at 2.5% of body weight three times a day for 8 weeks. The highest final body weight (83.10 g), specific growth rate (3.12% day -1), and body weight increase (51.1%) were obtained in the fish fed with 1 g kg−1 curcumin (p<0.05). The highest number of red blood cells and white blood cells were measured in C1 treatment. The immune responses were significantly influenced by different curcumin levels in the diets (p<0.05). The alternative complement pathway, lysozyme, and respiratory burst activity were significantly increased, especially in the fish fed with 1 g kg-1 curcumin. In conclusion, the results indicated that 1 g kg-1 curcumin notably enhances growth and non-specific immune responses in Siberian sturgeon. |
