Abstract

The effect of replacing maize with fermented cassava (Manihot esculentus) supplemented with enzyme on the growth response, nutrient utilization and histopatholgical parameters in the diets of Clarias gariepinus fed with various inclusion levels of fermented cassava supplemented with enzyme and maize were investigated. The initial mean weight of the fingerlings fish was 3.37, the protein content of the feed diet was 40% CP.

The livers observed under histopathological parameters in this study proved T3, 50% fermented cassava supplemented with enzyme to have no visible lesion on both plates of liver in T3. The histopathological parameters were represented by plates 1A - 5B. There were no significant difference (p>0.05) among the treatments in the final weight and MWG, It was observed that the highest weight gain value was recorded in (T2) containing 11.60g. Percentage weight gain (PWG) of the experimental fish equally did not show any significant difference. From the experiment, 50% fermented cassava supplemented with enzyme replacement was recommended.
