They are eating machines. Usually they are full of other fishes fry, often crappie fry. We use 1 oz Mann-o-lures or 7/8 oz bomber spoons, preferably in hammered chrome, bounced off the bottom aggresively. One reason for the big spoons is to get back down to them quickly before they move. They are aggressive. We have caught them not a whole lot longer than our spoons. These spoons seem to help weed out the little ones. Fish in the early morning will be from surfacing in shallow to 17 ft. When the sun raises they will drop back to 15-30 ft of water. I will run 15 lb big game and my ugly stick, because once in a while you will get a surprise. Have caught an occasional flathead and up to 30 lb smallmouth buffalo on them. Now is the time you can catch a lot of them. Watch your graph and when the bottom 2' is covered you are in them. If fishing with someone that is less industrious, rig a weight on bottom with a small circle hook tied with a dropper loop up about a foot. Use a small piece of fresh cut bait(white perch works well), worms, or minnows and have the weight just contact the bottom. We have done well on the east side north of the boat ramp, but they are everywhere. I am trying to get my old boat back together to get after them. They are really nomadic, if you are not catching them move. Often you will find more aggressive schools. Sometimes a move of 30 ft may put you in them. We will usually catch 100-150 in half a days fishing, and hit the electric knife. They are really good eating and multiple really quickly. We try to catch all we can, but I am afraid we are losing the battle. Come on Blues, get to eating. If you have problems catching them, pm me.
