Study of effect of Zn exposure on some biochemical parameters in air breathing fish, Heteropneustes fossilis

The present investigation has been designed to study the effect of heavy metal Zn on the blood glucose, plasma protein, cholesterol and enzyme activity in Heteropneustes fossilis after exposure of 24hrs, 48hrs, 72hrs and 92hrs. The present study shows that serum metabolites such as glucose, protein and cholesterol were increased while liver cholesterol and serum alkaline were increased. Thus, this study gives an overview of the manipulation of fish, Heteropneustes fossilis as a biomarker of heavy metals through alternation in biochemical parameters
