Effect of arsenic on certain biochemical parameters in liver tissue of tilapia mossambica

In the present study, the sub-lethal effects of arsenic on various biochemical parameters of Tilapia mossambica were studied. The fish was exposed to sub- lethal concentration of arsenic for 15 days for chronic toxicity studies. In the present study, total protein, amino acid and acetylcholinesterase, glycogen and lactic acid were observed. The present study showed the protein content was decreased and amino acid content was increased significantly and also Acetylcholinesterase was increased in the liver tissue of arsenic treated fish, Tilapia mossambica. The present study shows the level of glycogen decreased and lactic acid increased in the liver tissue of fish exposed to arsenic. These changes were concentration dependent.
