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.
Bass appear to have two effects on bluegill. First, bass simply eat a lot of sunfish helps control their numbers. Second, bass force small, vulnerable sunfish into thick weeds; but the big sunfish -- too large to be eaten by the bass -- are free to forage wherever food is most plentiful. So the presence of bass reduces the competition between small sunfish and large, thus allowing the large sunfish to grow even larger and faster.
