The Hybrid Bluegill is a cross between a male Bluegill and a female Green Sunfish, and is sometimes referred to as a Hybrid Sunfish. As a result of the cross the Hybrid Bluegill is ~80-90% male, giving it a reduced reproductive potential and making it an ideal choice for those ponds prone to Bluegill stunting. Keystone Hatcheries utilizes “Out of Season Spawning” techniques to hatch the fish indoors during the winter. This ensures a 100% pure cross, unlike many hybrids hatched in ponds, and it gives us a good supply of fingerlings early in the growing season. The Hybrid Bluegill is a voracious feeder, depending mostly on insects, zooplankton and very small fish. For this reason, they should only be stocked in ponds with a strong forage base. Generally, we recommend 500 Hybrid Bluegill per Surface Acre in ponds 2 acres or smaller.
