I've been putting in some thought on long term survivability of forage fish in the pond, and I wonder if stocking YP will make this even more challenging for me?

If your goal was primarily trophy SMB would you stock YP or leave them out of the mix? I know the YP will provide a lot of forage for the SMB, but they will also eat a lot of the other varieties of forage in the pond and possibly make the long term chances of their survival less likely?

Would a scenario of SMB and RES stocked with FH,GSH,LCS,Killifish and crayfish be a better long term setting to meet my goal?
