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 (p<0.05). However, the condition factor was the highest in the control group and there was no significant difference between control group and the other treatments (p>0.05). 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. 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.
