Rookie Question

[breaktime]

What does F1 or F2 next to a fish name mean? Some sort of ranking?

[Steve]

I'm sure others will chime in because I could be wrong, but I believe F1 means one generation away from wild caught, F2 means two generations from wild caught. At least I think that's how that works. Could be wrong.

[PowerCerg One]

That's correct, Steve.

[breaktime]

ok thanks for clearing that up. I would of never guessed that.

[Arturtle]

I believe the F designation can also be used for line breeding/hybrids, but I am not positive.

For the most part it is used to designate generations from wild, as others have said.

[Ogre44]

I believe that the F stands for Filial, which pertains to an offspring's relation to their parents.

[TrailerParkFishTanks]

Also if you see WC next to the the name its wild caught.

[atmagoulick]

Thanks,

I did not know that either.

I believe that the F stands for Filial, which pertains to an offspring's relation to their parents.

And in the fish world we don't use the Filial system properly and only use it as a designation to the origin of wild caught fish.

Also if you see WC next to the the name its wild caught.

Or "F0".

[Ogre44]

Or "F0".

I thought that just designated rude fish

The F designation applies to the number of generations removed from the wild so, F₀ means wild, F₁ is the first generation tank raised and so on.  Knowing which generation a fish is helps in crudely understanding how much or how little gene diversity there likely is present in a strain.  It is believed that maintaining the wild traits is reinforced by keeping the gene pool diverse or, in other words, rotating new stock into one's breeding groups.  As certain species become generally common and breeders do not consciously mix in other strains of the same species to maintain a diverse gene pool, it's more common to see misshapen or deformed stock in succeeding generations.  That is believed in many cases to be caused by not maintaining a diverse gene pool.

And here I thought I was asking a silly question  ..........  Good stuff I'm glad I asked
