title: Dietary amino acid profiles and growth performance in juvenile kuruma prawn Marsupenaeus japonicus.
abstract: To assess the reference dietary amino acid profiles for juvenile kuruma prawn Marsupenaeus japonicus a feeding trial was conducted using six semi-purified diets containing casein-gelatin and pre-coated supplemental crystalline amino acids (CAA) and a control diet containing intact protein (casein-gelatin). Pre-coated CAA were supplemented to the diets to simulate dietary amino acid profiles to those of the prawn egg protein (PEP), prawn larvae whole body protein (PLP), prawn juvenile whole body protein (PJP), squid meal protein (SMP), short-necked clam protein (SNP) and brown fish meal protein (BFP). The result showed that kuruma prawn juveniles are capable of utilizing the pre-coated CAA and higher growth performances were observed in the groups fed the PJP, SMP and the control diets than those fed the PLP, SNP, BFP and PEP diets. The essential amino acid proportions (A/E ratios) of the whole body of kuruma prawn differ slightly when compared with the other penaeids or freshwater prawn. The results suggest that PJP and SMP would be suitable as a reference dietary amino acid profile for juvenile prawn.
