30 year old brine shrimp eggs

Sounds like a silly question:
How did you hatch it? in details.. Did you rehydrate it?

If you still have some eggs left, you could try to decapsulate them using bleach.

Nice attempt though.

Well here's what I did:

-made a hatchery out of a 2 liter bottle.
-filled it up with 2 quarts of dechlorinized water
-salted the water with 4 table spoons of "table salt" (is this why it didn't work? Is there different salt for aquariums?) Other then possibly using the wrong salt the water was salted according to the directions on the package.
-added 1/2 teaspoon of eggs
-added an air tube to keep the eggs moving
-added a heater to keep the water at 80F
-shined a 60w incandescent light on the whole works
-waited 3 days.

and nothing.


Thats about as detailed as I can go. And yes I have 100's of thousands of eggs left. If I did something wrong im willing to try again

they can be kept dried for 15 years. within 15 years they will hatch for sure.

Well I generally follow the steps found here:
http://www.sfbb.com/faqs/hatchingbshrimp.html

First thing, mind the temperature. You might lose all brood if temperature is greater than 30degreesC.

Second point, you should hydrate the eggs in plain water for at least one hour before adding salt.

Third point, I'm not sure about why use table salt(I think they add fluorine in it). I use unprocessed salt(Directly obtained by evaporation of sea water) In your area you might get rock salt which can be used too. Don't buy the salt used for aquaria, it might be quite expensive.

update?

Quote from article:

The pH of the water should also be between 8.0 and 8.5. If your pH is below 8.0 your hatch rate will drop dramatically.

The PH straight out of my tap is 6.8
If I understood the article baking soda increases PH?

If we can clear this up I might give it another go.

non iodized salt

EDIT: Whats is non iodized salt?

At almost any grocery store, you can get Kosher salt, which is perfect for aquaria use. It is the same stuff as "aquarium salt", and at maybe 1/10th the price.

I find it a shame that it didn't hatch...

Could have been one of those "you wouldn't believe it" type stories...

baking soda is sodium hygrogen carbonate( or sodium bicarbonate) Its really cheap stuff available from your grocery. add a pinch to the water.

non-iodized salt is untreated salt. That is, no iodine compound has been added to it.
