In order to search the index of the starvation of the cherry salmon young fish of a river life term, this natural fish of the nature of spring, the product from a hatchery, and winter is used. Respectively triglycerides in liver (TG) and glycogen (GC) Change of the content was analyzed. it is not concerned with the difference in a season or a fish or tallow triglyceride content decreased gently. The tendency for the dying fish to appear was suited the time of the value of TG content of a fast group becoming low intentionally rather than the value of a feed group. Therefore, a possibility of becoming an index of the starvation in connection with TG content and life and death was able to be considered. On the other hand, it was thought that the GC content should take it into consideration according to a season for a trend to consider it as the index of a difference and starvation.
