Brine Shrimp Cysts Hatching Method & Trouble Shooting Guide
Hatching methods
1) Prepare hatching solution from non-iodized salt.
2) Incubate and aerate cysts in a conical shaped container
with cyst to solution density not exceeding 2 grams
per liter.
3) Provide hatching tank with natural or artificial light and
maintain constant temperature of 82 degrees (28 deg. C).
4) Stop aeration and remove fresh nauplii after 18-24 hours.
Note : If cysts are frozen or held in cold storage while in
inventory, allow cysts to acclimate at room
temperature for at least 5 days before attempting to
hatch.

If you have followed the above procedures for hatching Artemia cysts and are still experiencing poor hatching results, the following may help to determine the reason(s) why.
problem. Insufficient chlorination will definitely have an adverse effect on the hatch rate. Also,over chlorination (depending on levels) could cause decapsulation or at least the beginning stages of decapsulation. This too, will adversely affect the hatch rate. Also, make sure the
chlorine being used is of good quality (Chlorine that sits around for extended periods of time will weaken in strength and lose its effectiveness).
