The inquisition into feed flotation has led to the bio-chemical combination of some conventional feedstuffs with Duckweed Lemna Paucicostata meal fixed at 0, 4, and 8 percent in iso-nitrogenous 30% crude protein, iso-caloric 37 kcal/g diets for Oreochromis niloticus fingerlings mean weight ranged 21.00 21.50g in a fifty-six day feeding trial. Significant (P<0. 05) feed flotation were obtained at 4 and 8% over 0% Lemna inclusion. There were no significant differences (p> 0.05) in growth food utilization and survival of fish in all diets. The Cost evaluation and Feed Conversion Efficiency were positive in 8% Lemna diet than the whole artificial feed. However, because of the positive imparts on tilapia culture, Duckweed meal was recommended up to 8% inclusions in diets for tilapia fingerlings.
