I don't know (does anyone for sure?) if the GSF in my old pond were pure, but to my knowledge the original ones that came from the puddle I left behind that turned out to be the brood stock would have been as pure as was possible. As far as I know, there were previously never any BG in that pond.
Since I have stocked BG, RES and also put some known hybrids in there, with future generations who knows. But I think the originals would have been as pure GSF as possible for this area.
