Impact of cypermethrin on biochemical aspects of clinical importance in the blood of freshwater fish Cyprinus carpio

Abstract

LC50 96 hr value of cypermethrin to the freshwater fish Cyprinus carpio (Linn) was determined through static bioassays. The fish were reared in sublethal concentration of the pesticide for 28 days. Blood was collected from the treated and control fish and used for clinically important biochemical analysis. The biochemical variables such as glucose, urea and creatinine increased in the blood of C. carpio whereas the proteins, albumin and globulin decreased significantly. The study evidenced that the fish might have experienced a higher energy demand as well as conditions like hyper glycemia, proteinemia, liver damage, kidney destruction and muscle destruction under cypermethrin exposure.
