We compared egg number and the eyed egg rate between artificial and natural spawning sites in streams for both masu salmon Oncorhynchus masou masou and red-spotted masu salmon O. m. ishikawae. No differences in egg number or eyed egg rate for both subspecies were found between the artificial and natural spawning sites. Artificial spawning sites may enhance reproduction of masu salmon and red-spotted masu salmon in degraded streams.
