This study assessed the effects of sublethal Cd exposure (0.66 mg·L-1) on Labeo rohita (n = 270) of different size groups over 1, 7, and 14 days. Results revealed that Cd accumulation in gill, intestine, and kidney increased significantly, with the highest levels in smaller fish. Antioxidant enzymes (CAT, SOD) and GST activity declined, particularly on day 14. Treated groups showed elevated liver/plasma protein, glucose, and cortisol levels, indicating oxidative stress and disrupted biochemical homeostasis. Smaller fish were more affected. These findings highlight Cd toxicity's implications for aquatic ecosystems and human health, emphasizing the need for environmental monitoring and pollution control.
