The f and number is used to represent the generation of the animal. Wild
caught animals are referred to as F0, the first captive offspring are
referred to as F1, their offspring (grandchildren of the F0) would be F2 and
so on.

I think it is intended as a universal term for how far the animals are
removed from the wild. In many animal markets wild caught animals are not
the preference (due to collecting issues and health/acclimation problems
among other things) where in some fish varieties wild caught (or F0) would
be highly desirable.
