The Bluegill is a freshwater fish and a member of the sunfish family (family Centrarchidae) of order Perciformes. It is native to a wide area of North America, from Québec to northern Mexico, and has been widely transplanted to stock game fish for anglers. It is commonly fished in Minnesota, but it is the state fish of the U.S. state of Illinois. It is renowned as an excellent tasting fish on par with Walleye
Of typical sunfish body shape, the bluegill's most notable feature is the blue or black "ear", actually an extension of the gill cover called the opercular flap. Its name, however, comes from the bright blue edging visible on its gill rakers. It can be distinguished from similar species by the (not always pronounced) vertical bars along its flanks. The bluegill grows to a maximum overall length of approximately 40 cm (16 in).
Bluegills are popular game fish, caught with live bait, flies, hot dogs, raw chicken or other lures, chiefly at dawn and dusk. One of the easiest baits to use for them is white bread or a corn kernel. Another efficient bait would be redworms or waxworms on ice jigs.
The Bluegill goes by other names such as bream, brim, or coppernose.
