Surefire method? Really? I don't believe that a blanket statement such as this will apply to every situation. HBG have their place, and when properly managed will do quite well, and will NOT become GSF.
urup, congrats on the fish!!
The most common hybrid bluegill is crossed with the green sunfish. A redear cross would be labeled as such and worth more as they're far superior in beauty and size. With Hybrid Bluegill/Greenies you're basically stocking fish that are half green sunfish. Eventually some of the offspring will resemble green sunfish more than bluegill.
I didn't say they didn't have a purpose either. The do have bigger mouths than bluegill.
