The effects of supplementation of dietary medium chain triglycerides (MCT) at different levels (0, 2, 4, 5, and 6%) to the commercial diet on the quality of Ayu Plecoglossus altivelis were evaluated morphometrically and biochemically. The supplementation of MCT was effective to accelerate body weight grain and to suppress lipid accumulation in the body. Body weight and muscle mass increased and the intraperitoneal fat body, hepatosomatic index, and viscerosomatic index decreased gradually with the increasing level of MCT. The highest weight gain and the lowest lipid accumulation were observed in the 6% MCT sup-plemented group. Supplementation level of 6% or more would be available for the im-provement of growth without deposition of lipid in the body. The view that MCT can used to improve the quality of fish has been further strengthened.
