I was back in SE Minnesota this week, and did a night of mudcat fishing from shore in the Winona area after a day of fishing from my boat for walleye. The walleye were not biting, but the mooneye were.
I have heard of people having great results with fresh cut mooneye for cats, but when I have tried it in the past I got nothing but turtles. None the less, I kept one mooneye for cut bait. In the past I just threw bait-bound mooneye on a stringer, but this time I wrapped it in a plastic grocery bag and tossed him in my cooler with ice as soon as I caught it.
After dark, I set up on one of my flathead shore spots, and put out live suckers. Nothing. So I tossed out a rig with fresh, cold, mooneye steak, just to see what would happen. Within five minutes I had a run, which I assumed would be a gar. Instead, it was a 25″ channel cat. While my (baitshop) sucker was largely ignored, I got runs non-stop for the first couple hours on mooneye steaks. Then things quieted down, although I did get a mudcat on a sucker. I missed most of the mooneye strikes, which I suspect were either gar or turtle. I did land several more 20″ish channel cat on mooneye meat.
Anyhow, I am convinced that mooneye steaks work very well at least some of the time after dark for channel cat. I wonder if chilling the mooneye right away after catching it made a difference, since I never had any results with them in the past when I let them lay in the sun before slicing them up.
