I hate full moons for catfishing. The fishing is always screwed up, and more often than not, nothing bites anywhere near usual times.
I have beeter success fishing daylight hours than with a full moon in the sky. It doesnt make much sense, but its a definate pattern in my success.
My most successful outings have been the 4 days leading to the new moon cycle, but often times the new moon, or the day after.. the fish do the same thing for a night or 2.. turn off. Why, I have no idea, I wish I knew.. but it is a consistant pattern for me.
Anything is better than a full moon!
