In: Mansoura Unviersity Journal of Agricultural Sciences 2008.v.33(10)Summary: This study was conducted to determine the nutritional value of different protein levels of practical diets for Nile tilapia (Oreochromis niloticus) fingerlings (mean initial body weight 14.789). The experimental diets were designed to contain four different dietary protein (CP) levels, 20(D1), 25(D2), 30(D3) and 35% (D4). The results showed that there were significant differences (P<0.05) among the final average body weight of fish (at the end of the 12 weeks feeding period). The average final body weights of fish fed the experimental diets were 99.62, 100.74, 107.32 and 116.9/g for fish fed D1, D2, D3 and D4, respectively.
