I know perch eat them. But I've never heard of walleye eating them. I guess thats one positive thing to come from them.They are providing food for gamefish.
While ice fishing Black Lake in northern NY we had perch spit up zebra mussels. There are no gobies in there and the small perch were only as big as some of the gobies I've caught on Lake Erie.
ive used dollar bills for stripers, then used muscles for sport billybono
