| Popis: | The replacement of fish meal (FM) by corn gluten meal (CGM) in practical diets for juvenile spotted rose snapper, Lutjanus guttatus, was evaluated. Six isonitrogenous (47% crude protein), isoenergetic (19.03 kJ g−1) diets were formulated by replacing 0, 20, 40, 60, 80, or 100% of FM protein with CGM protein. Diets with CGM inclusion were supplemented with crystalline Arginine (Arg) and Lysine (Lys). Juvenile fish (mean body weight 31.2 ± 0.3 g) were fed the experimental diets (n = 45 per diet) for 70 days. Growth performance, feed efficiency, hematological parameters, protease activity, body composition, and nutrient digestibility were evaluated. Growth performance and feed efficiency at 60% FM replacement showed no significant differences (P |
