Not really
The Fx system comes from crossing experiments in genetic sciences. There F0 is wrong, and should be P, as the parent generation gives offspring (filia in Latin, hence the F)
We however do not intent to cross at all, and therefore all generations are supposed to be similar. Further, we see a contimuum between the fish in the wild, and the fiosh we have in captivity
Therefor I would not know which generation is the parent generation. Thus we start with the zeroth generation offspring, which were collected in the wild - F0
