A feeding trial was conducted to determine the effects of different feeding levels on growth performance and body composition. During 31 days, the experiment was carried out in the “Dunărea de Jos” University facilities from Galați, Romania. 720 fish, with an initial weight of 10.92 ± 0.17 g, were randomly distributed in twelve RAS rearing unit, with the same stocking densities. Four experimental variants were created, in triplicate: V1 - 3% from body weight per day (% BW day-1), V2 - 3.9% BW day-1, V3 - 4.9% BW day-1 and V4 -6% BW day-1. Fish were fed with 45% crude protein and 16% lipids at a feeding frequency of three meals per day. At the end of the experiment, significant differences (p˂0.05) were recorded between the four experimental variants. The body composition showed significant differences (p<0.05) also. The highest protein content and the lowest lipid content being recorded in variant V4 with 6% BW day-1.
