Abstract
Abstract We report a promising dietary model for amino acid (AA) requirement studies in fishes. An eight-week feeding trial was carried out to compare the efficacy of free leucine (Leu) and dipeptide Leucinyl-Glycine (Leu-Gly) in diets for olive flounder. Growth performance and whole-body AA compositions were examined. Triplicate groups of fish (average weight, 0.27 ± 0.001 g) (23 fish per replicate) were fed seven isonitrogenous and isocaloric experimental diets containing 6 (basal), 9, 12 and 15 g Leu/kg diet in the two different forms. The basal diet contained 6 g Leu/kg from fish meal and the other six diets were prepared by adding 3 g incremental levels of Leu or Leu-Gly. Growth rate was significantly (P
