All interested need to remember the basic genetics of HBG.
Firstly - The best available hybrid bluegill (HBG) is the result from cross breeding a male bluegill (BG) and a female green sunfish (GSF). Most often, but not always the MALE BG and FEMALE GSF are used by hatcheries for the genetic cross breeding, but there is no rule that is what has to happen. Hybrid BG (HBG) can also occur with either species as male or female. Hybrid bluegill percentage of males ranges from 66%-99% (often 80-95%) depending on the parent species. mBG (male BG) X fGSF (female green sunfish) is a common genetic cross for HBG and results in the higher percentage of males(hopefully 90%-95%). IMPORTANTLY - Percentage of males ranges from often 80%-95% depending on the parent species. If your cross is the alternative cross a fBG (female BG) X mGSF (male green sunfish) then your percentage of males will be in the lower range 66%-80%. See the twist? The source of your stocker HBG and which parent was the MALE is a big very important part of your HBG fishery.
Secondly- Once you have F2 HBG (second generation) the male or female can reproduce with any type of HBG from any generation. Each non-standard cross will likely produce closer to a 50% mix of males & females. Again see the twist? Some of this could be going on in the ponds with the problems described of too much reproduction from HBG.
