Believe me it's been tried......I fished over some condos that were dropped by Gasper Goule a couple of yrs ago.....nuthin'....... I should have been suspicous when game and fish were counting and measuring every crappie brought out of that lake for several months straight 2-3 yrs back. I just assumed at the time that they were glad the Crappie were in there..........but maybe they were just checking to see how much mossy cover to eliminate and how many Crappie Eaters to turn loose to keep the population down so they wouldn't compete with the bass???? Anyway, for whatever reason, the crappie are really hard to find and catch at LM now.
