SPG

Sorry I misread your post...you have GSF, but no verified female BG yet - no BG reproduction? If that's the case I think you dodged a bullet. Still you could be seeing lepomis reproduction/recruitment of hybrid BG/RES, GSF or PS - but I don't think that's a bad thing. Good news is those F1 fish should be mostly male, and may not serve as a management issue at all provided you make an effort to keep population in check.

If you don't have BG reproduction in your fishery I think you may be able to manage the GSF without doing anything other than population management. Remove all GSF you can through angling, trapping, seining, and cast nets when fish are feeding. I think the opportunity to catch BG, HBG, PBG or BRES is pretty cool.
