I look at them just out of curiosity, but have never taken them too seriously for fishing. I believe the barametric pressure of a given day has more of an impact on the fish than does the gravitational effects of the moon, etc. Most of the waters we fish aren't large enough to be tidal like the gulf, oceans or the great lakes. Quite the contrary when it comes to hunting, though. I know a guy here that is a very successful whitetail hunter who swears by the moon charts.
