I m wandering if the attenuation of visible light in lakes could be used as an indicator for the predation risk for zooplankton, while they do the diet vertical migration. 

I have searched on google scholar, not found any information on this subject, however, most articles have the basic data of fish biomass and light attenuation coefficient (Kd). 

I suppose if there is no direct link between those 2 factors of DVM. It might be good to do an meta-analysis for this kind of study. 

I just want to know is anyone have maybe study on the same topic?
