growing up my dad always told me the bigger the moon the less catfish bit. i'm sure he was told this from my grandpa who was a trotliner from way back. my dad and i fished practically every weekend till hunting season started. i've always found this to be true. about 15 years ago my brother in law and i took a weeks vacation and night fished below a lock here in ok. it was in the spring. the moon happened to be close to full. every night the bite started right at 1:00 am and lasted till around 1:30am and that was pretty much it. i came to the conclusion that maybe the feeding "window" is not open as wide when the moon is in its larger phases. i don't let the moon keep me from going because i'm like most folks i work so i go when i can. i do know i don't catch as many fish at night when the moon is larger. i would like some insight from anyone out there that watch the moon phases while fishing.
