How To Hatch Brine Shrimp?

Hatching Brine Shrimp is a very simple process that requires only five things:

  1. Seatures™ Brine Shrimp Eggs
  2. Bottled Water (avoid using tap water) 
  3. Seatures ™ Water purifier (or 100% pure, unprocessed salt without any additives) 
  4. Light source
  5. Brine Shrimp aquarium

In this blog post, we'll provide you with everything you need to end up with baby Brine Shrimp with the easiest hatching method for your next aquarium hobby. 

Brine Shrimp, as the name suggests, require salt water as their hatching solution. They can live in fresh water for a very short duration of up to 30 minutes. 

The first step in the hatching process is the preparation of the hatching solution:

Using bottled water is highly recommended as tap water often contains chlorine that may shorten the life of the Brine Shrimp. Furthermore, tap water contains various metals that can damage the egg.

The salinity for hatching the Brine Shrimp Eggs is calculated as one and a half tablespoons of Seatures™ Purifier for every quart of water (or 1.2 liters of water).

The purifier must completely dissolve prior to adding the eggs to assure an even salinity of water. 

The next step is adding the eggs to the hatching solution.

Using fresh eggs is very important as the shelf life has a direct impact on the hatching rate.

The eggs will gradually sink to the bottom of the water tank, if they float you can stir the water with a spoon during the first hours.

There are several tips you can use to make the baby Brine Shrimp hatch faster in the ideal condition and increase the hatching rate too. 

The water temperature is very important for the Brine Shrimp hatching, the optimum water temperature / Optimum Hatching temperature should be about room temperature (range between 20°C25°C or 68°F79°F) to decrease the hatching time and increase the hatch rate. A warm incubation temperature works wonders on the hatch rate and survival rate so if you live in a very cold area you may consider using an aquarium heater. 

The eggs require light to hatch as part of their hatching mechanism.  Keep the aquarium in a well-lit area, avoiding direct sunlight for the entire incubation period. Remember that water evaporates with time so adding salty water is advised for keeping a sufficient water level at all times.

Another important thing to keep in mind is the PH of the water, keep it around the PH level of 8 for the entire life cycle of the Brine Shrimp, from baby Brine Shrimp to adult Brine Shrimp. You can decrease the acidity of the salt solution with Sodium Bicarbonate (baking soda).

During the incubation period, adequate aeration should be provided. If you do not have an air pump that provides strong aeration, using a pipette to draw some air will do.

Proper Aeration during hatching will not only increase the survival rate during the first hours post hatch, but will also mix the eggs with the salty water.

Within a time period of 24-48 hours of incubation, considered the optimum incubation time,  (slightly less if you are using a Brine Shrimp Hatchery) the eggs will start hatching. A floating egg shell / outer shell is expected hours after hatching.  You can use a small net to keep the water surface clean. Un hatched eggs may require additional incubation time. Be patient as the time period varies based on the physical condition of the egg and your saltwater aquarium. 

Aerate the water every 1-2 days as explained above.

Keep a sufficient water level as water level will decrease due to evaporation (No need to add any additives but only bottled water as the existing additives do not evaporate)

Feeding starts three days after hatching. 

The kit comes with a 6 month supply of food, each month requires the content of one capsule. 

Carefully open the capsule and empty the contents to a small container, use a very small amount of food each time (just a few small grains picked by the tip of your finger is more than enough)!

Feed every 3 days, avoid overfeeding.
