Abstract– Chlorpyrifos (CPY), an organophosphate pesticide, has been extensively used in agriculture to manage pests. However, its widespread application has raised concerns about its potential toxicity to non-target aquatic organisms, particularly freshwater fish. This study investigates the effects of sublethal concentrations of chlorpyrifos on biochemical parameters in the freshwater fish Anabas testudineus. Fish were exposed to 5%, 10%, and 20% of the 96h LC50 concentration of CPY over a 96-hour period. The study assessed blood glucose, serum cholesterol, and plasma protein levels. The results revealed significant alterations in these biochemical parameters, indicating the toxicological impact of CPY on the metabolic functions of Anabas testudineus.
