I would not rely on CP to control PS reproduction to prevent stunting. RBS would likely be a better option.
CP are not as nearly picky about their spawning needs as are NP or musky. CP tend to not compete overly well with LMB or even SMB, more so with the LMB though. I see CP in ponds that are high acidic where LMB cannot live or struggle to live. That is where they excel...
