I fish an 6 acre pond and a 25 acre pond. Both are extremely clear. Originally these ponds had lots of white crappie stocked by well meaning neighbors. The neighbors no longer fish it, at least while we are watching, and the white crappies have been replaced by big black crappie. Unless you have a very clear pond, I would suggest staying away from crappie. If it is very clear, BC may be able to sight feed and be fed upon to control them. This is just my observation. I would defer to those on here that may have more technical knowledge. Good luck on your new pond.
