How to Hatch Baby Brine Shrimp


Live baby brine shrimp are an easy live food source to hatch at home and are an excellent supplementary food source for small freshwater or saltwater fish, as well as marine invertebrates.

Supplies you need to hatch baby brine shrimp:

  • Air pump
  • Airstone
  • 3 ft section of air pump tubing
  • Baby brine shrimp cysts ()
  • 2 quart or larger canning jar (new, or not previously used to store non-food stuffs)
  • Freshly prepare synthetic seawater with a specific gravity of 1.020-1.022 at 80 F.

Step 1
Fill your canning jar approximately 2/3 full with your fresh salter mix, and add 2 teaspoons of brine shrimp cysts (you can use more or less depending on how much you want to hatch out)

Step 2
Connect your airstone to your pump and place inside the container.  You want a vigorous “current” in your jar, but not so much as to cause the water to bubble out.  At this point, it may be a good idea to lightly cover the opening with aluminum foil to keep the saltwater from splashing out.

Step 3
After 24-48 hours, the brine shrimp should hatch, and you can turn off the airstone.  Shine a bright lamp at the bottom of the jar.  After 10 minutes, you should see a light orange mass of baby brine shrimp congregating at the bottom of the jar while the empty cysts float at the top.

Step 4
Insert your extra section of air pump tubing into the jar and suction the baby brine shrimp into a smaller container.  You feed them directly to your fish, and store any extra in the refigerator for 2-3 days.

Step 5
Clean your container and airpump out and repeat the process or store until you next hatch out more brine shrimp.
