| Outline of Final Research Achievements |
In this study, bacterial key species which would regulate organic matter flux in a bluefin tuna farming environment have been identified. Bacterial production in seawater was enhanced by released coral mucus regardless of the season. It was found that only a few bacterial species were dominant in the community of active growing bacteria from the analysis of next generation sequencing, suggesting they play a key role in the enhanced production. These bacteria should be "key species" as regulators of organic matter flux in the bluefin tuna farming environment where corals inhabit.
