We fish for them all the time here in Ohio. Fine eating.
Bluegills, green sunfish, pumpkinseeds, redears, longears and shellcrackers are all sunfish (plus a few others). Note the small mouth and disc shape as compared to a crappie.
I've noticed that Southerners seem to call everything perch, whether they're in the perch family or not. My father-in-law does that, too, and it drives me nuts when he's fishing up here in the land of yellow perch, walleye, saugers and saugeye - all members of the true perch family.

IMO, for their size, you can't beat the fight in a bluegill. - Roberta
