WHOLE-BODY AMINO-ACID-COMPOSITION OF EUROPEAN SEA-BASS (DICENTRARCHUS-LABRAX), GILTHEAD SEABREAM (SPARUS-AURATA) AND TURBOT (PSETTA-MAXIMA)WITH AN ESTIMATION OF THEIR IAA REQUIREMENT PROFILES

The amino acid compositions of whole body tissue of European seabass, gilthead seabream and turbot of two different size classes were determ ined. No significant differences were detected between species and the composition was not affected by body size. Based on whole body indisp ensable amino acids (IAA) to total IAA ratios (A/E ratios), the IAA re quirement profiles for the three species were estimated and compared t o data available to date for some amino acids, obtained using dose-res ponse curves.
