FWIW local pondmeisters have had very little luck maintaining a healthy population of BCP. My YP outstrip them in reproduction and voracity. I started off worried about my 1/2 acre pond being overrun when I first learned about the issue of not being a small-waters fish. Now I am concerned they are slowly fading away.
If I were to guess, the perch love the cool climate and waters, and out-breed them.
Plus my waters are alkaline and not very fertile.
So like anything else here, it depends...
