Warm? At 75F, I find about 75% hatched in 24 hours.
You want to use the baby brine shrimp as soon after hatching
as you can to get the maximum nutritional value from them.

I have two 'soda bottles' going, and harvest the 24 hour shrimp,
then leave it to 'cook' another day. I use use up, empty the older
bottle from the day before, and start another hatching in it.

One tablespoon of non-iodized salt (Kosher, table, rock)
Plus a 1/4 tsp of baking soda & a 1/4 tsp of epsom salts.

I've read, but haven't tried, a 24 hour light yields better hatch
rates.
But, I'm satisfied with the rate I get (eggs that settle to the bottom
supposedly are the unhatched eggs. floating shell hatched)

Interesting. They used to sell a device in the UK which did more or less
the same thing, with the added advantage that the bit in the light was had
a net built into the bottom attached to a handle that poked through the
surface. You just pulled the handle up and all the BBS were pulled up
with it. I used one for years, and occasionally I would buy eggs that
failed. Eventually practically all the eggs failed, and they took the
device off the market.

The explanation given at the time was that UK eggs used to be harvested
from Lake XXXX and that now they came from Lake YYYY, and that Lake YYYY
eggs needed aeration

>"Why can't we just feed brine shrimp eggs to fry?"

Because it's not digestable..
Because the fish won't eat them.

Use the amount of eggs that yield the amount of
naupli you'll feed. The "hatchery" described earlier,
is fine for San Francisco eggs (no air stone) but
doesn't work with Great Salt Lake eggs (needs air)
