How long can brine shrimp cysts last?
Brine shrimp cysts have been found in Great Salt Lake geologic core samples up to 600,000 years old, so we know they’ve been in the area for a long time. Brine shrimp cysts are packaged and sold as Sea-Monkeys. Brine shrimp cysts can remain viable for up to 25 years.
Why are my brine shrimp eggs not hatching?

Will brine shrimp lay eggs?
Brine shrimp have the ability to produce dormant eggs, known as cysts. This has led to the extensive use of brine shrimp in aquaculture. The cysts may be stored for long periods and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans.
How do you Decapsulate brine shrimp eggs?
1) Put the 1/3 cup of water into the mixing container. 2) Add the 1/2 Tablespoon Brine Shrimp Eggs into the mixing container. 3) Use the airline tubing to aerate the eggs for about an hour and stir them up several times during the hour.

How do you keep hatched brine shrimp alive?
Harvest the baby brine shrimp (BBS) into a fine mesh net and rinse with fresh water. Divide the harvest from 1 gram of brine shrimp eggs into 3 or 4 shallow dishes (petri dishes) with a saturated brine solution. Place the dishes in the refrigerator. The BBS should remain alive for 2-3 days for later feedings.
How long can brine shrimp eggs lay dormant?
two years
These eggs, also known as cysts, are metabolically inactive and can remain in total stasis for two years while in dry oxygen-free conditions, even at temperatures below freezing.
What do you do with unhatched brine shrimp eggs?
Allows you to feed even the unhatched eggs to fish, since the undigestible outer layer of the egg is no longer present.

How long do baby brine shrimp live after hatching?
