The worse problem that several students have worked on here is mortality from mosquitofish. Like you said Bruce, they can raise them just fine, here, TN state hatcheries, CFI, TNARI, but the mortality rate is so high its nearly futile. The real key is finding places where mosquitofish aren't or can be 100% eliminated. Just met the new student the other day working on exclusion and survivability.

They are state threatened I believe.

John, I suspect you're talking about Barrens Topminnows, Fundulus julisia.
Pat Rakes of Conservation Fisheries, Inc. in Knoxville did a widespread
survey for them several years ago, and as you know they've pretty much
disappeared from most of their original range. They may be down to two
springs, maybe three, all on private land. For a variety of reasons they
don't have federal protection, but the state of Tennessee extended some
level of protection to the species (I forget which off the top of my head).
If you found a new (or rediscovered, really) site that would be impressive.
Breeding this species is not a major challenge, the CFI people have produced
lots of them and I think there's still an exhibit-in-the Chattanooga
Aquarium with lots of them. Habitat protection is the name of the game, and
there are limited sticks to use on private landowners (like, almost none).
One of the ironies with this species is that a major threat to their springs
has been tree farmers raising saplings to be distributed through the
National Arbor Day Foundation; many of these farmers are kinda slack with
their soil conservation efforts, which of course destroys key habitat for
this fish.

I hope you find Barrens topminnows, and not their common distant cousin the
northern studfish, F. catenatus.
