I was having the same issue and finally found a set up that worked, a swim jig paired with a MegaStrike fat shad swam slowly. Even then the bites a few and far between. I literally ran a crank bait into a what looked to be a nice 3lb bass and it just moved slightly forward to get out of the way. Seconds later a very large school of fry showed up and I couldn't get him to bite, he knew what I was up to so I gave up and went home .
