Sublethal Copper Exposure Effect On Protein Metabolism In Fish, Oreochromis Mossambicus (Peters)

Authors(2) :-Jagadeshwarlu. R, Dr. G. Sunitha Devi

The natural aquatic systems have been extensively contaminated with heavy metals released from domestic, industrial and other man-made activities. Among all types of pollution, aquatic pollution is of greater concern as each and every kind of the life depends on water. Pollution of the aquatic environment generally causes changes in the physiological and structural aspects of the inhabitant organisms, particularly the fishes. Heavy metals cause several ill effects to aquatic organisms and environment. In the present study, Oreochromis mossambicus were exposed to sublethal concentrations (1/16, 1/12, 1/8 and 1/4th of 96 hours LC50 value) i.e. 3mg/L, 4mg/L, 6mg/L and 12mg/L of Copper Sulphate for four different exposure periods of 10, 20, 30 and 40 days. The proteins, Free Aminoacids, Aspartate amino transferase (AST) and Alanine amine transferase (ALT) levels in two different tissues such as Gills and Kidney were studied. Decreased tendency was observed in protein levels and an increased tendency was observed in Free Aminoacids, AST and ALT levels in all the vital tissues of fish exposed to Copper Sulphate over control. Proteins gradually decreased, Amino acids, AST and ALT levels gradually increased with increased exposure period and the increase was observed to be directly proportional to increased sublethal concentrations.
