Oxidative Stress Bio-markers in Labeo rohita Fingerlings Exposed to Silica Oxide Nanoparticles

Background: The present study was conducted to study the Oxidative stress bio-markers in Labeo rohita fingerlings exposed to Silica oxide nanoparticles. Methods: A total number of 180 fishes were randomly divided into 4 groups with 15 fishes each viz. E0 (control), E1 (SiO2NPs @ 2 mg/L), E2 (SiO2NPs @ 4 mg/L) and E3 (SiO2NPs @ 6 mg/L) and each group was set in triplicates. After acclimatization period of 14 days fishes were exposed to SiO2NPs in groups E0, E1, E2 and E3 and oxidative stress was estimated every 15 days up to experimental period of 90 days. Result: Findings showed a significant decline in Catalase activity and Superoxide dismutase and an increase in Lipid peroxidation at the end of the experimental period in the fingerlings exposed to Silica oxide nanoparticles.
