The purpose of this research was to investigate the effect of sub-lethal concentrations of silver nitrate (AgNO3) on antioxidant and stress genes expression and some biochemical indices of zebra fish. For this purpose, zebra fish with the average weight of 0/5±0/03 g were exposed to different levels of silver nitrate (T1: 10%, T2: 25% and T3: 50%) and control group for 14 days, each containing 3 replicates. At the end of the experiment, samples were collected to evaluate Sod, Cat, HSP70 and IGF-I genes expression and some biochemical factors including: ALP, ALT and AST. Results showed that genes expression (SOD, CAT and HSP70) were up-regulated at 25 and 50% which had significant differences with control (P<0/05). The highest IGF-I level significantly was observed in control and the lowest expression was in 50% treatment (P<0/05). ALP, ALT and AST activities in fish exposed to 10% silver nitrate had remarkable differences with others groups (P<0/05). Therefore, it can be concluded, silver nitrate had destructive effects on zebra fish which can be used to evaluate the effect of heavy metals on fish.
