This study was conducted to evaluate the effect of different concentrations of selenium and zinc nanoparticles on growth performance, survival and chemical composition of Whiteleg shrimp (Litopenaeus vannamei). For this purpose, shrimp with an average weight of 5.1±0.2 g were distributed in 12 fiberglass tanks with 25 shrimp density and were fed for 56 days with different concentrations of selenium and zinc nanoparticles in four groups with three replicate including 0 (control), T1 (0.3 mg/kg of selenium nanoparticl), T2 (0.15 mg/kg of selenium nanoparticle+ 15 mg/kg of zinc nanoparticl) and T3 ( 30 mg/kg of zinc nanoparticl). Based on these results, weight gain increasing, specific growth rate and feed conversion ratio in T2 treatment compare to T1, T3 and control treatments (p<0.05). Also, there is significant differences in survival rate between T1 and T2 treatments compared to T3 and control (p<0.05). Statistical analysis showed that there was a significant difference in protein and lipid carcass percentage between shrimp-fed diets containing different levels of selenium and zinc nanoparticles compared to control treatment. In general, the effect of different concentrations of selenium and zinc nanoparticles, especially in the T2 on growth performance, survival and chemical composition was positively and significantly evaluated.
