I ran across a situation that I didn't expect today, the big girls had started to move shallow and I don't believe it was a feeding migration. It got me to thinking about the influence the amount of daylight has on seasonal fish movements. I know that in the spring, despite cooler than ideal water temps,. a large percentage of the bass will spawn based on the angle of the sun/ length of daylight/ moon phase. I never considered it to be a factor in the early fall, but after browsing through my fishing logs, I discovered that, despite the water temp. that first movement happens right around the new moon every September here.
Unlike their movements in the spring when they'll retreat to deeper water and back during early pre-spawn, what my experience shows is that once they begin that movement in the fall, they don't retreat to deeper water until the winter cycle begins. Can anyone confirm my suspicions or post links to articles that talk about the early fall migration? If this is, in fact, a general rule to follow, I and you can eliminate any areas below a certain depth after the movements begin. I don't know about you guys, but anytime I can narrow down my search, prior to getting on the water, it gives me more time to locate that zone the fish are using and at this stage of my life, time management becomes a major factor.
