Popis:	We conducted a 26-week study to evaluate the performance of cage-raised hybrid Striped Bass (female White Bass Morone chrysops × male Striped Bass M. saxatilis) fed fish meal (FM) and soybean (SOY; soybean meal + soy protein concentrate) based diets. A FM reference diet was formulated to contain crude protein (CP) at 450 g/kg, lipid at 120 g/kg, and an estimated digestible energy level of 13 MJ/kg. Two test diets (SOY and SOY+GBA) were formulated to replace 70% of the CP in the reference diet with SBM in the absence or presence of GroBiotic-A (GBA), a yeast-based prebiotic, at 20 g/kg. The other 12% of dietary FM in the reference diet was replaced with SPC in the test diets, further reducing FM inclusion to 70 g/kg. Each diet was fed to quadruplicate groups of 40 advanced juvenile hybrid Striped Bass (initial weight ∼ 54 g/fish) stocked into each of twelve 1-m3 floating cages, which were equally divided into four 0.05-ha, rubber-lined ponds according to a randomized complete block design.
