Abstract
In order to identify the feeding stimulants for flatfish, the feeding tests were conducted using some diets added the amino acids, nucleotides, betaine and TU and acid hydrolysates to basal diet formula, respectively, The feeding stimulant activities and synergistic effects of those compounds were evaluated by a bioassay method. The KH, a kind of acid hydrolysate, possessed a remarkable feeding stimulant activity. It's stimulant activities were increased up to the concentration of $1.05\%$ (w/v), and were independent of pH. The formulation of KH and glycine had a most synergistic effect, The feeding rate of diet with feeding stimulation was 1,4 fold than that of diet without one. The costs for optimum formulation of feeding stimulants were cheaper than some additives in diets. It suggest that the results can practically used in preparation of diet containing feeding stimulant effects for flatfish.
