| Abstract;Ayu Plecoglossus altivelis with 11g initial body weights were reared on two different diets. Growth, feed utilization, characteristics of gut, and the ingestion of nutrients were investigated. Two experimental diets were prepared, crumbling the extruded pellet produced Diet 1, and Diet 2 was prepared by cutting extruded ingredients into a disk shape. Diet 2 maintained its shape in water and in the fish gut for a long time and gave better results in terms of growth than Diet 1 and there were significant differences in feed efficiency and protein efficiency ratio. The characteristics of gut, such as intestine size, and height of tunica mucosa, and height/intestine diameter ratio were variable in response to dietary types. Fish fed Diet 2 had more muscle protein and but less lipid than fish fed Diet 1. These findings demonstrate that dietary types affected the characteristics of gut and digestion system in ayu.
