Perch Pond, it all depends on how many YP are in the pond, and what size they are. In my case I don't think the GSF would have been a problem if SMB would have been stocked after year 1. If there are predators in the pond that are able to eat the GSF, then no worries.

It also depends on how the pond was constructed. In my case, there was no water that could flow over the ground to bring GSF into the pond, so that hasn't been an issue since I killed it.

In your case, if water can flow into the pond that may be contaminated with GSF, then they could be reintroduced to the pond.
