Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Large mouth bas vs blue gill

Like CB1 sez, no.

IIRC BG & LMB, when force crossed in the lab or hatchery, exhibit some success as far as eggs being fertilized, but very little success at producing viable hatchlings and virtually none grow to adulthood. I have a copy of the paper showing this at home, and ewest may be able to post the link.

IMO (like Cecil's) what you have is a SunfishXSunfish hybrid, quite possibly the classic BluegillxGreen Sunfish. GSF are frequently described as having a "bass mouth" as are the hybrids. It could just be GSF.

See HBG Pic/Question for pics of hybrids and GSF.
