Much of this can be traced back to vulnerability during two key periods – both the winter months where gills heavily concentrate, and during the spawn where high numbers of males guard beds. The age at which a bluegill becomes sexually mature depends on water temperature, available food, and competition, but it usually occurs around 2 to 3 years of age or when the fish is about 3 inches long.
