I have mentioned it before, but I am seeing it happen more than ever. Commercial Fisherman dropping Hoop Nets around Wingdams. You fish a wingdam and notice an area you can’t get passed, like a tree moved in. You lose a few lures, then just quit fishing the area because it’s too much trouble. When no one is around a commercial fisherman will show up and pull up his hoop net, or his gill net. He should throw back all the walleye, dead or alive. They are easy to notice because they are scarred up from the metal trap or from being buried under hundreds of pounds of carp in the bottom of a boat.
Here is what the rig looks like, they drop an heavy anchor of some sort, then feed out 50′ of rope, then the hoop net. After that they drop in a long rope with a visible float or an anchored float rig where they can snag the rope to retrieve the rig. It’s so long it’s pretty easy to find without a gps.
They drop these in front of wingdams, in any holes in wingdams and off the end of wingdams, everywhere where the walleye like to congregate. Most guys drop them below wingdams, where they are not in the way, but they do catch a lot of walleye and most do not check these every 2 days as required, they could sit for weeks or months as the fish slowly fill up the trap. They also drop these in along drop offs where all fish migrate through, usually ahead of wingdams. There are a lot of holes and shallows with lots of rough fish, I do not know why they have to drop these in around wingdams except maybe because it makes them easy to find.
