Photo Gallery: Fish: Bluegill
The bluegill is a deep, slab-sided sunfish with a rather small mouth. Males in breeding colors often have a deep red, almost dark brown breast. The side usually display vertical bars, but these are more prominent in smaller fish. The gill covers and chin are bright blue, giving the bluegill its name.

Growth of bluegill varies widely with population density. High population density retards growth while the opposite occurs with low density. Bluegill will reach 1 to 2 inches in length on the average in their first year of life. Bluegills mature during the second year under suitable conditions, but slower growth will delay maturity to the third year. Bluegill attain a length of up to 12 inches and weigh up to 2 pounds, but most bluegill caught by anglers seldom exceed 8 inches. The very popular and beautiful bluegill is also known as a sunperch, blue sunfish, copperbelly, copperhead, coppernose bream, redbreasted sunfish, yellowbelly, bluemouth sunfish, baldface, plumb granny, pumpkinseed, pond perch.
