I wonder if large predator fish such as catfish & musky would take over the bed. Probably would depend on how big an area the bed covered. I have a lot of excitement on a few of my beds (one's a pallet bed) once the catfish finish spawning and are very hungry. Hard to slow down a 20 or 30 pounder heading for the brush with a crappie rod, but makes for some excitement. Yet to land a musky, they straighten the hook or break the line.
