Abstract
The objective of this study was to evaluate the toxic effects on bioaccumulation, oxidative stress, immune responses and immune-related genes expression of Channa argus exposed for 28days with waterborne selenium (0, 50, 100, 200, and 400µg/L). After 28days, the order of Se accumulation in tissues was kidney > liver > spleen > intestine > gill > muscle. Antioxidant parameters in liver and spleen of C. argus evidenced an oxidative stress condition in waterborne selenium. In addition, immunological parameters and immune-related gene expression were all enhanced with an increase in Se expose levels. Our results suggest that waterborne Se exposure can induce considerable Se accumulation, oxidative stress and immunotoxic effects on C. argus.
