Assessment Of Superoxide Dismutase Activity In Freshwater Teleost Fish Labeo Rohita: Correlation With Environmental Stressors And Oxidative Stress Responses

Abstract

This study investigates the role of superoxide dismutase (SOD) activity in Labeo rohita (Rohu) as a response to environmental stressors, including dissolved oxygen levels and pollutants, along the Gomti River. SOD activity was measured in various tissues, including the liver, gills, and brain, across six experimental sites with differing environmental conditions. Significant variations in Cu-Zn SOD and Mn-SOD activity were observed, with higher enzyme activity linked to increased oxidative stress at sites with lower dissolved oxygen levels. Statistical analysis revealed a strong correlation between environmental factors and SOD activity, highlighting the enzyme's role as a biomarker for oxidative stress. The findings underscore the adaptability of Labeo rohita to environmental changes, and suggest that SOD activity can be used to monitor water quality and the health of aquatic ecosystems.
