| Outline of Final Research Achievements |
To test the possibility of direct selective breeding using wild parents for aquaculture, I have investigated and detected genetic effects of fugu <i>Takifugu rubripes</i> in the early mortality and growth rate and the resistance against monogenean parasite <i>Heterobothrium okamotoi</i>. Additionally, I have revealed that linkage disequilibrium rapidly collapse within 1kb. These results suggest large genetic improvement by means of selective breeding can be expected for fugu and direct selection on wild fugu requires SNP chip as large as 300k.
