PS only is excellent news!
They are certainly less prolific than bluegill.
I know some of the members in the northern U.S. have talked about PS in their ponds, but I am not sure we have anyone that has only PS as their sunfish forage.
Do you ever have grubs on the bass or trout that you catch in the area? I only ask, because that is a parasite that usually passes through snails. The most common solution is to add some redear sunfish to the lake to eat the snails. They live a little different lifestyle than the PS, and also are not too prolific.
If you have no snails (or can't get RES in your area), then I would post questions about your pond balance and mention PS as the only sunfish forage. That should get you some expert advice from the members that are really good at that stuff!
