ABSTRACT
The carcass composition and product quality of Clarias gaiepinus fed dietary levels of 0%, 5%, 10% and 15%, Ocimum gratissimum Leaf Meal (OGLM) was investigated. The 36% isonitrogenous diets were fed to the post fingerlings, randomly assigned to four treatments-control (Tzn), 5% (T0), 10% (T02), 15% (T03) in three replicates of 15 post fingerlings each using twelve plastic aquaria of 250 x 150 cm dimension. The fish were fed at 5% body weight twice daily within the experimental period of 56 days. Significant differences were recorded in carcass composition, with fish on Tzn and T01 diets having higher values in crude protein and ash content. Fish on T02 and T03 diets were higher in moisture content, lipids and nitrogen extract. Fish on Tzn diet were significantly superior (p<0.05) in quality to fish on T01, T02 and T03 (for raw fresh fish). However when cooked, the fish on Tzn and T03 were not significantly different (p>0.05). The results of this study showed that up to 15% dietary inclusion level of OGLM could support optimal carcass composition of Clarias gariepinus without grossly affecting the quality of the fish.
