| Outline of Final Research Achievements |
In aquaculture, selective breeding has not developed yet. The selective breeding takes much time to establish a new breed, so it is not adequate for aquaculture where new breeds are required immediately. We tried to develop new breeding method for aquaculture using genome editing technology, CRISPR/Cas9. With red sea bream and tiger puffer, the single guide RNAs were designated on the genome sequence in exon 1 of myostatin gene and microinjected into the one-cell stage eggs which are artificially inseminated. As results, the myostain gene of both fish has successfully disrupted and new breeds with enhanced muscle mass have established.
