The best Crappie pond I have seen was managed by accident, Every winter several High school boys would fish the deepest part of the pond and sack up a lot of nice crappie when it got to where they would only catch 4 or 5 they would quit. I saw this year after year. There were no bass in this pond. I don't know if that matters.
I have one pond with white crappie. I manage it fair I harvest smaller bass and turn loose any over 3 -4 pounds. I am building a pond downstream and before I do I will drain the crappie pond to prevent them from entering the new pond. I think if you really will eat a lot of crappie it is a fine choice. I also just cant hardly dump them on the bank. I clean a lot of 6" crappie.
I had another pond That I stocked crappie in and they never spawned as far as I could tell , no idea why.
Not sure I am any help
