A member of the sunfish family, the bluegill is one of the most popular freshwater game fish with anglers because of its tasty flesh and the fact that it puts up a pretty good fight for its size.
There is a limited amount of water that is able to be suctioned, so the fish must get within 1.75 centimeters. Bluegills also play an imporant 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.
