I bet they work just after ice out well but I've only heard that not tried it myself.

Hey Glenn, in regard to the perch/bluegill thing...at Piney Run we have noticed huge spawns the past few years and thousands of 4 to 7 in yellow perch are observed in the shallows from late April to late May. This year, alot of 12 to 14 in perch are caught around the docks this past 2 weeks on minnows and worms fished on the bottom. Just recently, however, and I believe in conjunction with the record high temps of a week ago, anglers were getting some bruiser gills in the mix, likely fish that are in pre-spawn mode as the water has actuallly dropped from 72 to 62 F this past week. We look for perch to fade out and gills begin to dominate during this overlap period of high aquatic activity that is seeing everything in the lake move shallow and feed aggressively. Hope it lasts a few more weeks!

what lakes and or ponds do you fish at?
