There is a lot more to come on this topic.
FYI to those who don't know . I have used Todd's fish ( Fla LMB And CNBG etc) and am pleased with the results.
Get PB mag - great articles on this subject and so many more. I will post one such article later.(no access right now).
iMO the reason no studies show outbreeding depression in natural LMB integrades is because what you are seeing in this zone is evolution at work - a new sub species of LMB is developing before our eyes.
