BT .... my money is on it being a hybrid Crappie. Check your pic against the one on this site and you'll see why : TWRA - Tennessee Wildlife Resources Agency - Black Crappie
According to the Southern Regional Aquaculture Center studies, hybridization between the Crappie species occurs naturally in the wild, due in part to several possible environmental factors. A female Black Crappie x male White Crappie hybrid shows higher survival, growth, and reproduction rates than a female White Crappie x male Black Crappie hybrid. But, there's literally no way the average Joe can tell which one occurred & produced their fish.
