| Outline of Final Research Achievements |
Deep-sea resource development at submarine hydrothermal deposit is important for us in our future. However, it is needed to conserve chemosynthetic ecosystems. Deep-sea resource development at submarine hydrothermal deposit is important for us in our future. However, it is needed to conserve chemosynthetic ecosystems around hydrothermal vent for development of deep-sea mining.
In this study, population analysis of vestimentiferan tube worm, Lamellibrachia satsuma, using lipofuscin, age pigment, as an age indicator and genetic analysis of COI gene. As a result, there were different age structure between two populations with same body size. Moreover, genetic structure changed by age structure. On the other hand, microbiota in an artificial chemosynthetic ecosystem tank (ACET) was analysed. It was cleared that the microbiota in ACET was resembled to the microbiota at the deep-sea whale-fall. The ACET was found to be effective in the observation of settlement of vent animal larvae.
