| Outline of Final Research Achievements |
Coral fluorescence has been shown to vary with coral health and environmental factors, making it a possible non-destructive proxy for coral health. However, due to the lack of adequate system for in-situ observation, available data are rather limited.
We developed a "handy multi-fluorescence imaging apparatus" based on the measurement of the fluorescent spectra of several coral species and marine organisms.This apparatus is constructed in six kinds of exciting lights (470, 530, 591, 617, 655 nm, and white (5650k)) and five kinds of cut filters(<390, <480, <540, <620, <640nm).This system allows the imaging of not only the conventional blue to red wavelength but also longer wavelength such as deep red fluorescence. In the future, such method will make it possible to understand the relation between corals' fluorescence and their physiology, and to provide an useful monitoring tool for more effective marine ecosystems managements and environmental impact assessments.
