| Outline of Final Research Achievements |
We proposed a mangrove killifish (Kryptolebias marmoratus, Km) as a new model for aquaculture. Km is the only vertebrate species known to reproduce by self-fertilization and therefore, each strain is a natural inbred strain. We established hybrid inbred lines between two genetically distant Km strains. A genetic map was constructed by RAD sequencing of the F2 individuals. 9,224 polymorphic RAD-tags (DNA markers) were mapped to 24 linkage groups. The total length of the map was 1,249 cM. The results demonstrate utilities of RAD sequencing on aquaculture.
