The present study aimed to examine individual nutritional and ameliorative effects of silica nanoparticles (SiO2NPs) and natural zeolite nanoparticles (ZeNPs) and their potential role as carriers to alter the bioavailability of curcumin. Common carps (Cyprinus carpio) were fed during 60 days with a control diet, and curcumin, turmeric, SiO2NPs, curcumin-loaded SiO2NPs, ZeNPs, and curcumin-loaded ZeNPs each at 1, 50, 6.15, 7.15, 39, and 40 g/kg diet, respectively. The highest weight gain (WG) and specific growth rate (SGR) were observed in fish fed with turmeric (P < 0.05). Moreover, dietary curcumin and ZeNPs increased the content of monounsaturated fatty acids (P < 0.05). After exposure to silver nanoparticles (AgNPs), the lowest amount of aspartate aminotransferase (AST) was obtained in fish fed with curcumin (P < 0.05). In addition, alanine aminotransferase (ALT) decreased significantly in the negative control, curcumin, and curcumin-loaded SiO2NPs treatments in comparison to the positive control group (P < 0.05). The lowest silver accumulation was observed in the negative control and SiO2NPs groups (P < 0.05). This experiment demonstrated that while the nanoencapsulation of curcumin on SiO2NPs and ZeNPs did not enhanced the impact of curcumin on the growth and biochemical factors of carps, it can still be considered a potential dietary supplement for enhancing growth and antioxidant indices when added individually to the diet.wysggggggtd5nzjfk
