There is very little written material (studies) on CNBG. I have seen none on F-1 BG and in fact never seen them referred to as that. If they exist ( and I think they do) then they do so in 2 of our ponds which have had both types stocked for at least 8 years. I have never seen one that I could tell was an F-1 or Fx. I would assume that they are intermediate between BG and CNBG but as to what genetic traits I don't know. It would be shear speculation on my part.

Walt were you aware that a least 1 state level manual ( by a PhD fisheries scientist) says don't stock just F-1 LMB in southern ponds because of the risk of genetic outbreeding depression? I don't agree based on studies I have read but we don't stock just F-1s because of the unknown potential.
