In re-reading this thread I am wondering why you stocked PS before the SMB since the original plan was to put PS in after SMB.
Yeah, it was the plan, but I kept being let down by fish farms not having the SMB.
Also, my usual fish farm told me to let the YP & PS spawn before adding predators, kind of opposite of what this forum recommends.
I just have a lot of trapping of PS for the rest of this year...
