Usually olive-colored with a purple luster, greenish stripes, and a large black spot at the rear of the dorsal fin. The sides of its head and chin are commonly a dark shade of blue, hence the name “bluegill”. Bluegills are most commonly found in lily ponds and around docks and boat landings. A favorite of both fly and bobber fisherman, the freshwater Bluegill is the most popular freshwater sport fish in the U.S. and is known as a tasty pan fish (just the right size for frying whole in the pan). State regulations apply, but “keeping size” is generally the span of your hand or larger.

Diet
Bluegills are carnivores, primarily eating invertebrates such as snails, worms, shrimp, aquatic insects, small crayfish, and zooplankton.
Behavior
Bluegill are most active at dawn. During the day they stay hidden under cover, and they move to shallow water to spend the night. Bluegill are social and schools may contain 10 to 20 fish.
Ecological Role
Bluegills play an important role in pond and lake management to keep crustacean and insect populations low, as a single bluegill population may eat up to six times its own weight in just one summer.
