Marc/Cecil -- just one small observation that may or may not be helpful. I fished one our ponds with good bluegills near the end of June. There is always a spawning colony on one particular point where a gravel bar runs out into the pond. The bluegills were there, as always. :-) Anyway, when I threw my jig/twister tail up in 3 feet of water, I always caught a male. However, when the wind drifted us off the bar, all the fish we caught in 5-6 feet of water were females. So, would the females gather near the colony, but not come in except to spawn?? I hate to draw a strong conclusion because this was just one day on one pond. However, that was my thought.
Actually, when I first saw Marc's post, I quietly waited to see if we could get a bunch of observations here. I was hoping to learn something! So, if any of you bluegill pondmeisters out there read this, please respond with your observations, even if limited. Thanks.
