No redear in there? They tend to grow a bit bigger than the bluegill and keep the snails under control.
Yep I’ve got nice redear in the pond. Quite a few of them >12” in size. They only spawn once per year so they don’t tend to get out of control the way bluegill do. I stocked the redear specifically for snail control so we don’t take them out unless gut/gill hooked and not going to survive. We swim in the pond and nobody likes a bad case of swimmer’s itch.
