ealong59 I missed your question early in this thread about HBG %s. There is a lot still unknown about HBG and a # of posts here discuss those matters. Studies on HBG are not in agreement on some issues. For example the male % of the cross BG x GSF ranges in studies from 66% to 98%. This is a large difference if you are counting on low recruitment rates. Some think that is partly a result of non-pure GSF stock. There is speculation and some info that suggests that there is a noticeable difference between a HBG from a mBG x fGSF and a HBG from a mGSF x fBG. There is data and conclusions wrt genetics that say which parental species is the male or female makes a difference in Centrarchid fishes. There is also serious question about whether a HBG can backcross with either parental species . There is proof that an Fx HBG can reproduce with its parentals (HBG) but at low success rates. Those factors alone are enough to make one scratch his head. There is almost no independent published info on GG from which to draw any unbiased conclusions.
