Bluegill
Bluegills were origionally introduced in 1932. Bluegills have blue coloring on the chin, a solid black opercle flap, and a small mouth. 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) 5-9 vertical bars along its sides. Their body is very compressed or flat.
Bluegills are an excellent fish for young kids to fish for. They are fun to catch and can usually be caught in numbers when you find a school of them.
Average Length: 4 to 13 inches.
Average Weight: 3 ounces to over 3 pounds.
Habitat
Bluegill are found in most reservoirs or ponds below 4,000 feet elevation and rarely occur in streams and rivers. They are prone to stunting and large populations of tiny bluegill are common.
Diet
Insects are the favored food but Bluegill will eat worms, snails and small fish.
