Egg laying

Hi everyone.  I was wondering what people's opinions were on the 
following:  when we set up fish in our lab, we typically remove dividers 
at 9am, when the lights come on.  Some people in our lab prefer to 
check the fish every 15-20 min to look for eggs, while others leave the 
fish until about noon before checking.  Does repeated checking disturb 
or stress the fish so that they might not lay/lay less eggs?  Is it better to 
leave set up fish completely undisturbed while waiting for eggs? 
Thanks very much,
