I've always used the website below because it provides information for any day, anywhere in the world. It also provides sunrise and sunset data. The peak feeding period begins one hour before moon transit, and then ends one hour after. A lesser eeding periods occurs 12-1/2 hours later. In other words, the theory is that fish and game are most active when the moon is directly overhead, and then again about 12-1/2 hours later. I have never followed the belief the minor feeding periods occur half-way between these two periods.http://aa.usno.navy.mil/data/docs/RS_OneDay.php
Looks like opening day morning should be a decent one this year, with the middle of the lesser feeding period happening around 9:30am. Definitely a morning to stay late.
I should add that times can differ from one source to another. That's why I have always followed the belief that the peak time is when the moon is directly overhead. It's simple and straight forward.http://www.acurite.com/moon-phase-hunting-fishing
