Hmmm ... again this is news to me. I would just say that BG-RES even if they are 97% male still need a predator. They will reproduce way too much without predator fish. Also, in a case where they are stocked with other species that will readily mix with them, their offspring will exhibit BG-RES characteristics. Where big BG-RES males dominate spawning habitat, there could be alot of that going on.

Just to give you an idea of how prolific lepomis species are ... RES which are considered low among lepomis for reproductive potential are stocked in Michigan DOW ponds at the rate of 5 pairs to the acre in the spring. On average by fall there is a crop of 25 to 30 THOUSAND 1" to 3" RES for stocking into Michigan lakes. So high reproduction even from RES which are considered low reproducers among lepomis species.
