Sublethal Effects of Paraquat on Some Plasma Organic Constituents (Metabolic Parameters) of African Catfish: Clarias gariepinus (Osteichthys-Clariidae)

摘要

The plasma levels of glucose, protein, cholesterol and triglyceride were determined in Clarias gariepinus exposed to sublethal concentrations of paraquat (0.30 and 0.15 mg L-1). There were significant decrease (0.05) in plasma glucose (showing hypoglycemia situation), plasma protein and triglyceride with a significant increase (0.050) in plasma cholesterol when compared with the control. These changes were directly proportional to the toxicant concentration and the exposure periods thus it is dose dependent and time-dependent.
