The replacement of fish meal with sunflower meal (SFM) in the diet formulation for sharpsnout seabream, Diplodus puntazzo (Walbaum, 1792) was tested. Sixteen baskets (300 L capacity), each with thirteen fish, were distributed in a recirculated saltwater system to allow four experimental diets containing 40 percentage crude protein (CP) and 20 percentage crude lipid (CL) with 0, 11.7, 23.5, and 34.8 percentage SFM partially replacing fish meal to be used in quadruplicate for this experiment. The fish were fed these diets ad libitum during the experiment, which lasted for 162 days. Growth, nutrition efficiency, biometrics, carcass composition, amino acid composition, and amino acid retention of the experimental fish were evaluated. Fish fed a diet containing 34.8 percentage SFM had the lowest feed intake (FI), lowest feed conversion ratio (FCR), and the highest protein efficiency ratio (PER)
