Histopathological Investigation On Superoxide Dismutase (SOD) Enzyme Activity Of Fresh Water Teleost Fish (Labeo rohita)

Abstract

Present paper deals with the investigation of superoxide on the physiological impacts of environmental stressors, namely pollution, on the health of freshwater teleost fish by investigating their histopathological hepatosomatic index (HSI) and superoxide dismutase (SOD) enzyme activity. Bindeshwari Fishery pond in Bhilampur, Jaunpur district, was used to collect fish samples. The fish's liver, kidneys, testicles, and ovaries showed major changes after being exposed to the contaminants, according to histopathological analyses. Normal cellular architecture and well-organized liver structures were hallmarks of the healthy histological findings seen in the control group. Atrazine, contaf, and fenvalerate, on the other hand, caused oxidative stress symptoms in fish, such as inflammation, cellular necrosis, and structural alterations in hepatocytes, which were associated with elevated SOD activity. These results point to a physiological reaction to environmental pollutants that cause oxidative damage.
