Histopathological and Biochemical Changes in Fish Liver Under Environmental Stress: A Case Study of Labeo rohita

Abstract

This study investigates the histopathological and biochemical changes in the liver of Labeo rohita (Rohu) under environmental stress, with a particular focus on the effects of oxidative stress. The liver, being a central organ in detoxification and metabolic processes, is highly susceptible to environmental changes such as pollution, temperature fluctuations, and low oxygen levels. In this study, we assess the histopathological alterations in liver tissues and measure key biochemical markers, including superoxide dismutase (SOD) activity, to determine the extent of oxidative stress. The findings highlight significant liver damage and alterations in antioxidant enzyme activity in response to environmental stressors, suggesting a close relationship between oxidative damage and liver function in fish. The results of this study provide valuable insights into the physiological adaptations of Labeo rohita to environmental changes and underscore the potential of liver biomarkers for monitoring fishhealth in polluted aquatic environments
