Descriptions
The effect of feeding stimulant mixture on feeding activity, grouth, feed efficiency and other physiological conditions of jack mackerel Trachurus japonicus were asseyed by using the formulated diet based on brown fish meal or casein. When fish of 6.0g average body weight were fed on diets with and without feeding stimulant, inosine monophosphate and tryptophan, for 30 days, feeding activity, growth and feed efficiency of the group fed the fish meal diet with the feeding stimulant were higher than the diet without the feeding stimulant, equivalent to the group fed sand lance Ammodytes personatus. These revealthat the feeding stimulant in the diet promotes feeding activity as well as digestion, absorption and metabolic functions of jack mackerel.
