Going on field experience alone I am a big believer in the moon effect for both animal and fish activity. I have had better hunting and fishing when the moon and sun are both up. Full moons can be tough if the rise, peak, or set don't fall near normal activity times. However, when there is a sunrise/set near a moonrise/set I have had very good luck. I hunt as much as I can but I try to spend my allotment of time in the woods when I feel my chances are best. I just checked moon data for the 5 dates and times that I shot mature (3 yrs or older) whitetails and all but one time had positive lunar effects. That buck was driven to me by other hunters. Go figure.
