INCORPORATION OF LOCAL PLANT RAW MATERIALS IN THE FEEDING OF JUVENILE NILE TILAPIA (OREOCHROMIS NILOTICUS, LINNE, 1758) IN SENEGAL, WEST AFRICA

A research for eight weekswas conducted to evaluate the effect of substituting fish meal with local agricultural products in diet Nile Tilapia (Oreochromis niloticus).Three treatment dietaries were prepared. The dietary composition tested diets is as follows: A1/plant based-diet (Groundnut cake, sesame millet bran, maize and 0% meal) A2/fishmeal partial replacement meal, 10% A3/fishmeal 25% meal). All isoprotein isolipidic diets. initial average weight was 3.45±0.5g. fishes fed twice a day triplicate weeks. After experiment, final weights 4.97±0.5g, 5.43±0.5g, 5.86±0.5g A1, A2, A3, respectively. There significant differences (p < 0.05) among three Feed Conversion Ratio (FCR) juveniles on A3 (1.77) significantly better (lower) compared A1 A2 (3.41 2.59, respectively). FCR not different. Specific Growth Rate (SGR), Individual Daily (IDG), relative gain However, they higher than those diet. no > 0.05)among all survival rate. This study revealed possibility but total substitution fishmeal by plant materials 3.45g Oreochromis niloticus fingerlings considering both growth economic factors.
