5,400 six inch Crappie a day is a problem, LOL.

I've fished a 4 to 5 acre pond once that was full of huge Black Crappie. A locale said it had stayed that way for 20 plus years. I think the key in this pond was it was also very heavy populated with pound and a half to two pound Bass. When I say heavy, I mean catching a 100 plus in an afternoon with a small spinner. Spannerking is correct, 99 percent of the time you'll just have a pond over populated with tiny Crappie. The reason it works in the sloughs and back water areas is during high water you get a big toilet flush moving many of them out.
