Outline of Final Research Achievements

Sex-determining genes can be used for sex identification, potentially providing important information regarding the ecology and conservation of many wild fish species, as well as management in aquaculture. Since the sex-determining gene(s) are not identified for most fish species and not well conserved among them, it has been difficult to obtain sex-specific markers for a target species of fish. In this study, we show that a combination of linkage and linkage-disequilibrium mapping implemented with high-throughput sequencing technologies is an efficient strategy for identifying novel sex-determining genes/regions in fish.
