Crappie, Bluegill and Sunfish...Well I have caught all and eaten all as a child! Crappie is pronounced Croppie in Indiana. Bluegills are of the Sunfish family, probably the crappie, too. But "sunfish" stay small...probably get eaten by other fish. Bluegills swim in a circle as you "haul" them in on an old cane pole...or modern equipment. Fall is the time to Crappie fish. Summer great for the others. Nothing scientific here, just old timer experience! Here in the South all grow larger because of the climate of course. All full of little tiny bones!!!!
Bluegill meat is very sweetlike for a fish. Now you know more than you want to...I am sure!
