摘要：

The sublethal toxicity of sodium arsenite on protein metabolism was investigated in teleost fish, Tilapia mossambica at the end of 24, 48, 72 and 96 h of exposure. Total protein content,free amino acid content and activities of the enzymes aspartate amino transferase (AAT) and alanine: amino transferase (ALAT) in liver, gill, brain and muscle exhibited significant (P<0.05) alterations throughout the investigation in relation to that of control. It is suggested that the fish is able to respond to the stressful situations by gearing up the metabolic activity as revealed by the elevated protein, amino acid content and the activities of AAT and ALAT.
