Sex determination in fish is often genetic, where segregation of sex-determining (SD) locus assigns the phenotypic sex. In these species, SD genes can be used for sex identification, potentially providing important information regarding the ecology and conservation of many wild species, as well as management of cultured species. However, no SD gene had been identified in aquaculture species at the time when this project started. We investigated fugu (Tiger pufferfish) that is one of the most important aquaculture fish in Japan. We provide a line of evidences showing that a SNP in the Amhr2 gene determines phenotypic sex in fugu. In addition, for high-throughput sex identification of fugu, we developed an efficient assay for this SNP site. Moreover, we successfully produced all-male population of fugu through marker-assisted selection.
