Michael, I'm not sure how freezing embryos would benefit Devil's hole
pupfish restoration. The fish lays eggs. Embryos are produced only
when the eggs are fertilized, of course. At that point, the best
husbandry would seem to be to grow them up to fry rather than to
freeze them. Or am I missing something about freezing them? Is it
that you think that might be a hedge, raise fry and freeze embryos for
later?

I don't think the problem-in-Devil's hole is that the habitat has
become unsuitable, though the water level has been a problem
sometimes. But isn't that solved for now-in-least? Or am I mistaken?
