Not really...

Predicting when "activity (feeding) windows" open is like guessing the number of jelly beans in a jar. That's why I said, "not really." The previous reply is pretty much right on. Get out there and get a bait in the water.

To answer your question...

Lots of documentation and studies exist around the relationship of the sun and moon to activity levels. Lots of it really helpful. Lots of it rubbish. And as every decent angler knows, weather/local conditions trumps just about any guess as to when and how long activity levels will occur.

Boiled down to a simple advice...

1. 1/2 to 1 hour before and after sunrise, sunset, moonrise, and moonset. (When the two events overlap all the better.)
2. 3 days either side of major moon phases. (People will tell ya all sorts of stuff about different quarters...just note the full moon and its opposite).

That said, fish when you can and keep a bait in the water (especially when the barometer is cooperating) and like the rest of us you can "hope to find a muskie." Try to fish days around major moon phases. Be on a prime spost around key times during the daily cycle (sun and moon/rise and set).
