There is limited Perch fishing in the area. Because of the high population of Pike most of the Perch stay in the thick weeds. In the morning if you are catching Walleye and it's in an area with thick weeds, then most likely the Perch are in the thick weeds. As the day gets brighter the Walleyes will slow down so try mooring into the thick weeds and fish straight down off the boat with a small hook and a piece of worm. If you stir up the bottom with your anchor you should attract more Perch from a distance. Make sure you have a second Pike rod handy. A perch feeding frenzy attracts big Pike.
With a sports fishing license you are allowed to bring home 50 Perch, which is a great way to have lots of fish for the big fish fry.
