Nutritional Studies on Partial and Total Replacement of Fishmeal by Jojoba Meal (Simmondsia chinensis) in Nile Tilapia (Oreochromis niloticus) Fingerlings Diets

AbstractThe present study was carried out to investigate the potential use and economics of replacement Jojoba meal (JM), Simmondsia chinensis, instead of fishmeal at different levels (0, 25, 50, 75, and 100%) through assessing the effect of adding Jojoba meal on growth performance, feed and nutrient utilization, and carcass composition of Nile tilapia, O. niloticus fingerlings.Fingerlings (average weight 1.65±0.01g/fing.) were stocked at a rate of 10 fingerlings/aquarium for.84 days experimental period. All experimental diets were isocaloric (437.69 Kcal/100g DM) and isonitrogenous (30.5% crude protein) and supplemented with L-Methionine (0.5%) and L-Lysine Hcl (0.5%). Results showed that there were a significant differences (P
