keep spreaders just off the bottom sometimes a slow lift and back down will help especialy when the bite is light. we also use crappie rigs sometimes in the mud sometimes a crank up from the bottom. kind of early for perch we went twice caught 21 1 time and 40 the next 4 guys western end of lake. fish for 20 minutes if you do not get them move got to find them also running your engine sometimes brings them in the perch are curious. good luck use shinners and get a limit. we keep 8 inchers and better
