Pat, even with the broodfish, if you find a skinny 8" BCP take it out. I stocked some 9"-11" CC in my pond years ago, and was removing them when they were around 5#. I caught one that was 12" long and thought that I had reproduction, which I didn't want. I then noticed the missing adipose fin, which I clipped off of all the stockers. That one didn't grow.
Same with the broodfish BCP. If you have one that isn't growing, why leave it in there to reproduce??
