Update #2
While there were more fry visible all over the lake, I saw something today I had never seen before.
Two weeks ago, there was a ball of about 1000 fry staying close to the dock, with papa bass swimming just out deeper than them, chasing off intruders. They were near the surface in about 3 feet of water. Today, that fry ball is no longer near the dock, but there is a much larger ball (I would guess over 10,000 fry) hanging out away from the dock, near the surface in about 8 feet of water. I am not exaggerating the amount of fry there were, the ball was as long as my 10 ft Pond Prowler as I drifted through them this afternoon. They were 20 feet away from the dock, but there is a sunken Christmas tree below them that may be the reason for them being that far from shore. I don't ever recall seeing fry that far from shore, but I also have never seen a grouping of them this large either.
So will different groups of fry join up together for safety? I would think there is a good chance they had the same mom, so they might be half-brethren and are just having a family reunion before 90% of them become meals for other predators.
BTW, the most effective lure today was a 3" tube, it produced the most bass and the average size was significantly bigger.
