Re: [Killietalk] Hybrids

What F1 means in fish terms is, the breeding of either unrelated parents OR
the first
crossing of wild parents. No hybred involved.... Spawning the resulting fry
from F1
to each other, would be F2, and so on...

I'm sure there are others on this list that can answer your other
questions....
