[Coral-List] Fluorescence of A. palmata/cervicornis under LED lighting.

[Tim Wijgerde]

Hi Damien,

If you study the work by Cecilia D'Angelo et al., it seems the production of bright, (non-)fluorescent colours in corals is stimulated by blue light. However, you don't need light that is optically blue, only a full spectrum white light source which has sufficient blue in its emitted spectrum. To properly reveal FP's, a blue/actinic light source is required. If you photograph them under blue or actinic light, combined with a yellow long-pass filter, they will look fluorescent green. Such footage is great promotion for these species if you want to share it with the public at large.

Cheers,

Tim

Hello Coral-list,

Has anyone grown A. palmata or A. cervicornis under high powered LEDs used for commercial coral aquaculture? I am curious if these corals, given time grown under intense but specific spectrum LED lighting would fluoresce like many Acropora sp. It’s my understanding aquaculture has mainly been 10-20k metal halides.  The advancement of modern LEDs could show their beauty much more and help give these endangered corals more of a fight. Even if it’s just time a lapse of a single branch fluorescing.

What is the scientific value to figuring something like this out?

Warm regards,
Damien Beri
