A total of 150 juvenile Clarias gariepinus of mean weight (17.14g) were randomly distributed in triplicate of 7 fish per tank. Graded levels of Baker’s yeast were mixed with commercial feed (COPPENS) at 0% (Diet 1), 2% (Diet 2), 4% (Diet 3), 6% (Diet 4) and 8% (Diet 5). Mean weight gain was significantly different with the highest MWG recorded by fish on Diet 3 (174.80g) and least on Diet 1 (116.85g). The least feed conversion ratio (0.56) was recorded in Diet 3 and the highest Diet 1 (0.71). The protein efficiency ratio was highest in Diet 3 (4.28) and least in Diet 1 (3.35) while the highest gross profit of (#1889.0) was recorded in Diet 3. There was no significant difference (P>0.05) in haemoglobin, PCV, Red blood cell, White blood cell, MCH and MCV across the test diets. The result of the organ analysis showed no significant difference (P>0.05) in spleen, kidney, heart, large intestine, stomach, bile, lungs and fat, while liver, small intestine and air sacs showed significant difference (P<0.05). The study showed that inclusion of Baker’s yeast at all levels of inclusion positively enhanced growth performance and feed utilization without any adverse effect on the fish growth and performance, though the best result was recorded at 4% inclusion.
