The Hybrid Bluegill is a cross between the Bluegill and Green Sunfish. They have larger mouths than straight Bluegill and are very aggressive feeders. This hybrid is 90-95% male and reproduction is minimal. This characteristic prevents the overpopulation problems seen with the straight Bluegill. Because of low reproduction, they should be stocked with a forage species such as Fathead Minnows. This will ensure that there is sufficient food to sustain a healthy Largemouth Bass fishery. The Hybrid Bluegill have a 4-6 year life span.
