Usage of Silver Nanoparticles progressingly expands in various industries. In order to study the probable usage of these materials in aquaculture, the toxicity effects(LD50) and Maximum Allowable Concentration (MAC) of Silver nanoparticles in the following four fish species, Ctenopharyngodon idella (cultured fish), Barbus grypus (wild fish), Cichlasoma severums and Astronorus ocellatus (ornamental fish), were calculated. The toxicity was calculated based on static OECD standard method. Each species were challenged with 8 serial dilutions of Nanoparticles and daily mortality was recorded for 96 hours. LC50 and MAC calculated using Probit software. Results showed that LC50 96h of Nanosilver in Ctenopharyngodon idella, Barbus grypus, Cichlasoma severums and Astronorus ocellatus were 0.12, 0.086, 6.85 and 7.89 µg/ml respectively, versus The MAC of Nanosilver in these species were 0.012, 0.009, 0.69 and 0.79 µg/ml. There was Significant difference among toxicity rate of silver nanoparticles among fish species (P<0.05). Although no significant differences were seen between Ctenopharyngodon idella, Barbus grypus as well as Cichlasoma severums and Astronorus ocellatus in Nanosilver toxicity, significant difference observed between these groups (P<0.05). According to the results of this study it can be conducted that reared and wild fish were more susceptible to Silver Nanoparticles than ornamental fish.
