This study was carried out to determine the optimum dietary supplementation level of oyster mushroom in cherry salmon (Oncorhynchus masou masou). Juvenile cherry salmon averaging 5.0±0.5g (mean ± SD) were fed one of the five experimental diets containing 0, 3.5, 7.0, 10.5 and 14.0% oyster mushroom (D0, D3.5, D7.0, D10.5 and D14.0) for 12weeks. Increasing of dietary beta-glucan content were observed at a high dietary oyster mushroom powder. After the feeding trial, average weight gain (WG) of fish fed D0, D3.5 and D7.0 diets were significantly higher than those of fish fed D10.5 and D14.0 diets (P < 0.05), however there were no significant differences in WG among fish fed D0, D3.5 and D7.0 diets (P > 0.05). Average feed efficiency (FE) of fish fed D0, D3.5 and D7.0 diets were significantly higher than those of fish fed D10.5 and D14.0 diets (P < 0.05), however there were no significant differences in FE among fish fed D0, D3.5 and D7.0 diets (P > 0.05). Average hepatosomatic index (HSI) of fish fed D0, D3.5, D7.0 and D10.5 diets were significantly higher than those of fish fed D14.0 diets (P < 0.05), however there were no significant differences in HSI among fish fed D0, D3.5, D7.0 and D10.5 diets (P > 0.05). Therefore, these results indicated that the optimum dietary supplementation level could be greater than 3.5%, but less than 7.0% in juvenile cherry salmon under our experimental conditions. And additional research on the immune response will be necessary to carry out.
