Abstract


Alternative protein sources are potential substitute for fish meal in the diet of spotted rose snapper (SRS). This study was designed to evaluate the partial replacement of fish meal protein with meat and bone meal (MBM), including tuna byproduct meal (TBM) as a reference ingredient in diets for spotted rose snapper (SRS). Three isonitrogenous (47.6-49.0% CP) and isoenergetic (20.9-22.9 kJ g-1) diets were prepared by replacing 35% of fish meal protein in the control diet (FM) with (MBM) or TBM. A 120 days growth trial was carried out in an indoor flow-through system in triplicate groups of SRS juvenile (average of 8.2 ± 0.02 g), fed to apparent satiation, three times a day. Growth performance, hematological parameters and digestibility of SRS from 8 g up to 98 g fed MBM or TBM diets were not significantly different from FM diet. However, the whole body crude protein was significantly the lowest in TBM group and the highest MBM group; and the values were comparable to FM group. Based on these results, the meat and bone meal is a viable option as tuna byproduct meal in practical diets for juvenile spotted rose snapper.
