In this study, the mutual effects of zinc nanoparticles (Zn-NPs) and vitamin E nanoparticles (Vit E-NPs) on growth and immune parameters of fingerling Cyprinus Carpio with an average weight of 9 g was evaluated over a period of 60 days in three different treatments (treatment I : 100 IU/kg normal vitamin E + 15 mg/kg normal zinc sulfate; treatment II: 100 IU/kg Vit E-NPs + 15 kg/mg Zn-NPs; treatment III: 300 IU/kg Vit E-NPs + 15 kg/mg Zn-NPs) compared to the control group that received normal diet without any supplements. The results showed significant increase in the mean percent body weight increases (144.1 ± 56.85%), average daily growth (2.41 ± 0.15 %), specific growth rate (1.46 ± 0.13 %/day) and feed conversion ratio (FCR, 4.59 ± 0.68), immunoglobulin (IgM, 4.49 ± 1.71 mg/dL) in treatment III compared to the control group (p0.05). The survival rate (%SR) was significantly increased compared to the control group, but there was no significant difference between different treatments (p > 0.05). Based on these findings, treatment III is recommended for increasing the growth indices and treatment II for enhancing immune parameters in C. carpio.
