I have been crappie fishing for about 45 yrs & I seen this one time in my life at Barren River Lake. During october when the lake was in winter draw down a big school of minnows (shad?) were close to the surface over a stump row and crappie was coming to the surface after them. We thru a jig about 6" under a bobber & caught several. They didn't jump like bass or stripe but swirled just under the surface where you could see them.
