- Abstract
The present study investigated the validity of two male-specific molecular markers, OtY2 and sdY, in two wild populations of red-spotted masu salmon (Oncorhynchus masou ishikawae). All phenotypic males were positive for both markers in both populations. On the other hand, some phenotypic females were also positive in each population: 32% and 11% in OtY2 and 71% and 67% in sdY. Individuals with no male-specific amplification would be identified as female, suggesting the applicability of these markers (especially, OtY2) when selecting females for life-history studies, strategic conservation, and effective breeding programs.
