Fish from dried eggs?

I was browsing the web for info on killifish and came accross a surprise. A product called Fish in a Jiff which hatches killies from dried eggs.

It didn't say the species name or where they were from. But it got me thinking. Can any north american species survive as dried eggs? If so this could revolutionize native fish shipping. Just have a species sent in diapause (I think that was the term) and rehydrate later.

We have Kryptolebias marmoratus, the mangrove killifish. I knew it came out of the water to lay eggs (climbing up mangrove trees), but now I'm seeing wikipedia says it can spend "up to sixty-six consecutive days out of water, which it typically spends inside fallen logs, breathing air through its skin". That is even more dry-resistant than I thought, wow. Here's a link to its eggs on aquabid being sold like any of the other dry killi eggs: http://www.aquabid.c...fishe1372546161

I wonder if any of the desert fish in the southwest have dry-defenses. Artemia (brine shrimp) and triops are native there and have a dry egg stage. Fairy shrimp eggs can completely dry out, too, which is useful because they live in temporary vernal pools.

You can buy fresh eggs of the Gulf Killifish, Fundulus grandis, from commercial breeders along the Gulf coast. They're not really dried out but they can be shipped damp. You could probably do the same with mummichog eggs, F. heteroclitus, and I would guess a surprising number of North American killifishes would be tolerant of such handling. Their distant annual life cycle relatives in South America and Africa are famous for producing eggs that may not hatch for years depending on how hydrated they are, or aren't, and hobbyists keep them soil that's as damp as pipe tobacco (if that registers with you).

Now I am reminded of a story Justin lawson said a few years back, where he went to collect livesand from the Rhode Island coast for his saltwater tank. Left it out to dry, and it rained and killies hatched from eggs in the sand.

Killie eggs can be dryish on the outside, but if too much water from the inside evaporates they die, which is why killie breeders keep the eggs in slightly damp peat in plastic bags. The egg shell is kind of like a Kordon breathing bag. They are not like brine shrimp eggs, which can be truly dried.
