The study evaluates the carcass composition and product quality of Clarias gariepinus fingerlings fed varying dietary inclusion levels of blood meal at different level of inclusion for 49 days. Six diets of approximately 40% crude protein were formulated with Fish meal, Blood meal, Soybean meal, Corn meal, Palm oil, Table salt, vitamins C, Bone meal, vitamin/mineral premix and starch, which served as the binder were used as feed ingredient, at 0%, 5%, 10%, 15%, 20%, and 25% levels. One hundred and eighty Clarias gariepinus fingerlings with mean length of 5.64±0.11cm and mean weight of 1.49±0.05 g were used for the experiment respectively, all treatment was in three replicates of 10 fingerlings each, using eighteen plastic aquaria of 250x150cm dimension. The fish were fed at 5% body weight twice daily within the experimental period of 49 days. There were significant differences (p<0.05) in carcass composition, with fish on Treatment with 25% (BM) diet having higher crude protein value, but least in moisture and nitrogen free extract. Fish before experiment were higher in moisture and ash contents, while there was significant difference (p<0.05) with initial fish before the experiment having higher in crude fibre of 0.45±0.01 and lowest in treatment with 10% (BM). The result noted a considerable effect on carcass of the fish with blood meal inclusion.
