Histological Changes in the Liver and Kidney of <I>Clarias gariepinus</I> Fed <I>Chrysophyllum albidum</I> Seedmeal as Maize Replacer

This study investigates the histological changes of kidney and liver of <I>Clarias gariepinus</I> fed diets containing <I>Chrysophyllum albidum</I> as maize replacer. Five isonitrogenous diets containing maize which was replaced by <I>Chrysophyllum albidum </I>at a rate of 0, 25, 50, 75 and 100% were made. The diets without<I> Chrysophyllum albidum</I> seedmeal served as the control. The diets were isonitrogenous and isolipidic. Experimental diets were assigned randomly to the tanks and each group of fish was fed 5% body weight in equal proportion per day. The results of this study showed that there was a marked vacuolation of hepatocytes among the treatments after the experiment which is not dietary treatment related. The experiment showed that it is technically feasible to replace maize with <I>Chrysophyllum albidum </I>seedmeal in the diet of <I>Clarias gariepinus</I> without adverse effect on the histology of kidney and liver
