I figured I would forward this to the acn-l list just for general info.
The question originally appeared on the killie list and this was my
response to it. Feel free to add to it.

Are you referring to killikeepers specifically or anyone keeping the
fish? In terms of North America the only species I am aware of that are
extinct in the wild and still in captivity are in captivity because of
the efforts of a few such as the folks at the Universidad Autonoma de
Nuevo Leon, Mexico and the subsequent exchanges with a few American
zoos. Some of these fish have gotten out to aquarists but it is largely
the zoos that are trying keeping the fish going permanently in captivity.

Species include:

Cyprinodon alvarezi
C. longidorsalis
C. veronicae (I think may now be extinct in the wild)
Megupsilon aporus

There is also a few Goodeidae and Poeciliidae in the same boat and there
will be many joining them in the coming years from northern Mexico.
