Is Your F0 Really F0

[nolapete]

I think the whole f# thing is a misnomer of sorts. If I understand correctly, this it how it works:

F0 = Wild stock
F1 = Progency of wild stock bred in captivity
F2 = Progency of F1 stock
and so on

Well, F1's are just as wild as F0's. They haven't been tainted with any captive bred stock, so the only difference is that they were born in captivity. Nothing genetic is different than their parents is it?

If I only use wild fish for breeding, why aren't the progency just wild instead of being F1?

Survival of the fittest...

If you catch a fish in the wild it has outlived the vast majority of it's siblings borrn at the same time... the fish's fittness helped it survive...

A F1 fish was nutured from birth... many F1 fish survive to be sold that would have parashed in the wild... the fish's owner helped it survive, not it's fittness...

It's all about survival of the fittest...

so what is when a F0 and a F1 breed

F2... although some say F1...

You cannot literally translate the F# scale, so there are some bumps...

The F# was established to help scientists track experiements. F1 was the the first generation of the experiment, F2 the second generation, and so on. It is very rare for these experiments to include crossing generations with each other, so there is no F# for doing so. In the rare cases this is done in science, they explain what happened and drop the shorthand (which makes a TON of sense, no shortening forefits detail).

F0 is also something that was not included in the original use of F#'s...

To many people try to whimsically "fix" the F system by their own whims... but the only way it has any value is if we all use it the same way... "fixing" it only further ruins it...

I used to think it would still be F1 but found out in a big discussion thread that the general consensus on this is that it would be an F2.

FINS..the fins on wild caught fish are mostly more tattered and split than captive bred fish because there r more dangers so they r more active and n older fish that have spawned they lay on the bottom to fan, hide and lay the eggs

In my experience, none of the fish we caught had tattered fins. I remember being very impressed by this. The opposite is true in fact. The Convicts and Motas we caught had Fin trailers that would rival those of show specimens kept solo.

I think the reason for this is fish that are injured(tattered fins etc.) by a predator and get away have a higher chance of being eaten later. they may not be able to swim as efficiently.

Actually the torn fins are from handling, not from the dangers in the wild. Fish in the wild usually are more spectacular because of the natural food selection and survival of the fittest as was said.

In regard to F#, it always defaults to the highest progency number. i.e. F0 x F1 = F2 not F1. F1 x F3 = F4 and so on. The designation is the generation of captive breeding genetics removed from wild F0 fish.

if u want's to be sure ........catch it ur self

it's the only way

ROFLMAO
