Effects of Chlorpyrifos Technical Grade on Glycogen Metabolism in Channa Punctatus

Author(s): Dr. M Sunanda

Abstract:

This study investigates the biochemical effects of chlorpyrifos technical grade, an organophosphate insecticide, on glycogen metabolism in the freshwater fish Channa punctatus. Glycogen content was assessed in the liver, brain, kidney, gill, and muscle tissues after exposure to lethal and sub-lethal concentrations of chlorpyrifos for 24 hours. The results demonstrated a significant reduction in glycogen levels across all tissues, with the liver exhibiting the most considerable depletion. The depletion of glycogen is attributed to increased energy demands under pesticide-induced stress, along with potential inhibition of enzymes involved in glycogen synthesis. This study highlights the adverse metabolic effects of chlorpyrifos exposure, emphasizing its potential risks to aquatic ecosystems.
