ABSTRACT: A 3-month randomized factorial design 4 × 2 (four levels 0, 15, 30, and 45%) of wet Date (WD), two levels (0 and 0.03%) of Digestarom? (D) and three replicates. The trial was conducted in twenty four glass aquaria. Ten fingerlings of Nile tilapia were placed in each aquarium with an average weight 15.40±0.3 g fish. Fish were fed twice daily (six days a week) at a rate of 3% of body weight. The results revealed that, mean final weight (g/fish), SGR (%/day), feed conversion ratio, PPV and PER, were significantly (p ≤ 0.05) affected by the levels of WD and level of D. And the best diet achieved which containing 30% WD supplemented with 0.03% D. From the above results and the economic information of these studies it can be concluded that, diet containing 30% of WD with 0.03% D exhibited the highest net profit and would seem to be the most desirable level of WD and D in the system studied.
