I don't fish deliberately for pickerel, but they occupy the same places as the bass where I fish, so you could say I'm fishing for either species when I'm in pickerel waters. They will take any lure that exists, from topwaters to bottom draggers and everything in between. If I had to choose one lure, I'd give the nod to spinnerbait, but not by much, as they will readily take anything.
They're fun to catch and I've always felt that they fight better than largemouth.
