Dave, that's about what I thought. I wanted help to manage it, not just stock it with larger fish. I asked what happens to the little fish that hatch, and he told me they get eaten, that's why I need big fish stocked. With that logic, you'll always have to stock forever. So, my plan is:
1. Kill the willow and water weeds, primrose I think.
2. Aerate
3. Put some type of structure for the little fish
4. Maybe feed?????

Again, thanks so much for the advice.
