Abstract: The present research investigates the toxicological impact of chromium (Cr)?on the freshwater catfish Clarias batrachus, commonly found in the aquatic systems of the Balrampur district, Chhattisgarh. The research focuses on identify histopathological changes in key organs (gills, liver, muscle) caused by metal exposure. Healthy specimens were subjected to controlled experimental conditions and treated with specific doses of metals. Observations were recorded at intervals of 24, 48, 72, and 90 hours (acute), 30?60 days (sub-acute), and up to 90+ days (chronic). The study concludes that Clarias batrachus serves as a sensitive bioindicator of aquatic heavy metal contamination. Its hematological and histopathological responses offer reliable biomarkers for early detection of ecological stress. The research emphasizes the urgent need for pollution control, water quality monitoring, and public health awareness in fish-dependent rural communities. It also advocates for future research into DNA-level toxicogenomics and bioremediation approaches to mitigate long-term ecological risks.
