Pond Boss Forums INTRO Questions & Observations Tiny crappie pond, need advice

I have a 2.5 acre old pond (40 + years) with BCP and LMB among other things. I had loads of stunted small crappie when we bought our place. We removed 200 each summer for 3 years. Once my LMB got a big enough gape (in my estimation) I started clipping fins off any BCP that was underperforming (thin body, big eyes like Pat says0 and tossing them back in for an easy to catch snack for the LMB. So all those things helped my pond. BUT....having 'good water' i.e. stable depth, weeds under some measure of control, dam and outflow in good repair, are key for ALL species. But crappie are an enigma. Why my pond produces some trophy size BCP and Pat's hasn't (so far) is puzzling.
