Claim:
1. An elapsed-time determination apparatus comprising: a non-transitory computer-readable storage medium that stores correlation information indicating a correlation between a state of a melanophore of a fish and an amount of time elapsed since death of the fish; and a processor that executes a control program to cause the elapsed-time determination apparatus to function as: an acquisition unit that acquires an image of a fish; an analysis unit that detects a state of a melanophore of a fish by analyzing the image acquired by the acquisition unit; and a determination unit that determines the amount of time elapsed since the death of the fish in accordance with the state of the melanophore of the fish detected by the analysis unit, based on the correlation information, and outputs determination results, wherein the correlation information indicates a correlation where the smaller the size of a black portion of a melanophore is, the longer the elapsed time after death is, and wherein the analysis unit detects the size of the black portion of the melanophore as the state of the melanophore of the fish.
