Brine Shrimp Eggs (Artemia Cysts) are harvested from salt concentrative ponds 

or salts lakes. Naupli hatched from the  cysts provide one of  Nature’s finest, 

nutritious foods for tiny shrimp and fish.

1. Hatching tank:  use a clear plastic or  glass bottle for small quantities.

2. Use  clean seawater or artificial saltwater with a specific gravity of 1.01 to 1.02. 

3. The optimum  pH is  7.5-8.5.  If necessary, add alkaline solution made from 

     soda ash or sodium sulfate  to raise the pH.   

4. During hatching, use sufficient aeration to keep all eggs in circulation at all 

     times.  Pump the air through  an airstone to get a smooth flow.
5. The optimum hatching temperature is 82-86  °F (28-30 °C ).

6. Most hatching will occur after 18-36 hours.

7. To harvest, remove the air supply and wait 10-15 minutes.  The naupli will 

    school on the bottom. Siphon them  into a fine mesh net by using a plastic tube.

8. Store cysts in a cool, dry place. For maximum preservation cysts can be frozen.
