Now I know that it technically means the generation of the fish from it's wild parent (F0xF0=F1, F1xF1=F2, and so on....), but what is the precise definition of it? Who made up the term? Is the F# referring to the generation of the fish from it's wild parents, or the generation of the clean bloodline? For example (F0(new blood)xF0(new blood)=F1(offspring of new blood) now take offspring from a different F0 pair: F1(pair 1)xF1(pair 2)= ? F2(new blood)). It's technically a new blood line, that is traced back to 2 separate parents, just as in the wild. No inbreeding at all (which imo is the whole reason the F# system is even used for fish...to tell how clean a bloodline is). Is it the same as interbreeding F1's from the same parents?
If the true definition for F0 is the "base" bloodline, then breeding a pair of F1's from 2 separate parents would bring the F# back to 0? But that sounds absurd right? If the true definition is the generation from wild parents, then that would make the F1's from separate parents F2, just as F1's that are inbred from the same parents. Either way, it get's pretty confusing. If it's generation from wild parents, how do you differentiate the F2(from F1 same parent) fry from the F2(from F1 different parent) fry? Maybe F2*! If it's bloodline how do you differentiate the wild caught F0 from the captive bred F0? Maybe just call them that... wc F0 vs cb F0!
Imo the wc F0 would still be a bit more desirable due to the fact that cb F0 don't have to deal with "survival of the fittest" in the wild as wc's do, thus making weaker fish from the brood, still able to reproduce. I'm not saying this is how it works, just pointing out the difference between a wc clean bloodline, and a cb clean bloodline.
Wouldn't it be less confusing to just label a wc fish as wc, and leave it to the breeder to explain the generation of the cb offspring? Example: your fish's grandparents were wc. Most people stop counting/caring after F3 anyways, so it shouldn't be that hard.
I'm not looking for any arguments, just some clarification and discussion. Thanks in advance for any input
