Abstract

The effect of induced ammonia toxicity on selected enzyme systems of
carbohydrate and nitrogen metabolism of freshwater fish, Tilapia mossambica was
studied. An increas-s in lactate dehydrogenase (LI>H) and decrease in succinate
(SDH) and malate dehydKjgenase activity levels were noticed in all the tissues
studied. The activity levels of asparate aminotransferase (AAT) decreased in all
the tissues, while that of alanine aminotransferase (AlAT) had shown an increase.
An elevation in the levels of Eirginasts activity and urea was found in the gill and
liver tissues. The mettbolic sigmficance of these results is discussed
