Yes on the shiners. Might be able to raise fathead minnows in that same pond concurrently. Probably need all the forage you can get. Maybe raise some bluegill in that pond too.
I like the idea of a larger predator like the tiger muskie, but also feel that would take a few years to make a huge difference. If you could do some electroshocking and use that as a major culling tool, along with some larger predators, you may see some results in a year or two.
