effects of shrinking zoox?

Hi coral-listers!

Does anyone know how gross primary production may be affected by 
decreasing/ shrinking zooxanthellar size in corals, clams or culture 
(assuming constant chlorophyll content and number of algae cells)? Will 
denser concentrations of pigments in zooxanthellae shade each other 
and decrease production efficiency, or what? 

I have been unable to find any references on this. I have only seen 
references where dense populations of zooxanthellae may shade each 
other and cause diminishing efficiency...
