Thanks ewest! I've considered a light stocking of adult PS as a fallback plan in case the initial forage base doesn't sustain itself well. Considering your comment, this makes me lean towards thinking that we could successfully manage the PS population in a small BOW, using GSH-YP-SMB to prey on PS from fry up to juvenile size, and then human predators to remove a few adults (given the small-sized BOW and that PS are quite easy to catch).
