The very best crappie pond I've ever seen for size had an extremely high density of small LMB. Very few YOY crappie survived each year due to heavy predation from largemouth. The survivors actually turned the table and began eating small largemouth.

The average sized black crappie was 13-14 inches. The average sized largemouth that we would catch was more like 9 inches.

There were apparently a few big LMB--likely they were cannibals.

Holding a redear sunfish is like running with scissors.
