[Coral-List] measuring light respiration in corals

Dear coral-listers,
for my PhD research I am trying to create energy/carbon budgets of
scleractinian corals growing in aquaria under different abiotic
circumstances. One important parameter in such an energy/carbon budget
is light respiration. So far I am aware of two methods to measure light
respiration: the stable oxygen-isotope technique and the light/dark
shift technique using microsensors. Is anybody aware of other methods
that may have been developed to measure light respiration? I was
thinking about using a photosynthetic inhibitor to temporarily knock
down photosynthesis and then measure respiration. However, the
measurement should be harmless to the coral (nubbin), because I need to
do more measurements on the same coral(nubbin) during the experiment.
Thanks in advance for any suggestions,
Miriam Schutter MSc.
