How to Raise Brine Shrimp at Home

If you’re looking for an interesting and rewarding project to do at home, culture brine shrimp!

It’s a fun and easy way to produce a high-quality, nutrient-rich food source for your fish and invertebrates.

In this post, we’ll walk you through the process of setting up a brine shrimp hatchery, as well as how to care for your shrimps.

Let’s get started!

What Is Brine Shrimp?

Before we get into the how-to, let’s take a quick look at what brine shrimp are and why they make good live food for fish.

Brine shrimp (Artemia salina) are a type of plankton that inhabit saltwater.

They’re small crustaceans that range in size from 0.5 to 2.0 millimeters in length and are a popular food for fish, amphibians, and crustaceans.

As juveniles, brine shrimp possess a characteristic orange-red color that fades as they age.

Brine shrimp eggs are also sold as a feed for fish, especially fry, as they are high in protein and other nutrients.

How To Grow Brine Shrimp

Now that we know what brine shrimp are and why they make good live food, let’s take a look at how to culture them at home.

1. Gather the Necessary Equipment for Brine Shrimp

five-gallon bucket or Large Rubbermaid box (for the adult culture shrimp tank)

Brine shrimp thrive in specific conditions and they need at least two containers for your brine shrimp.

You can use aquariums too; however, they aren’t necessary.

Two-liter soda container (for the brine shrimp hatchery)

A 2-liter soda bottle is another option for a hatching container. It just needs to be cleaned and sanitized before use.

Also, for better results, you need to use a 5-gallon bucket with it.

The choice of either an aquarium or a plastic bag is entirely up to you, and they’re both quite low-cost.

Sponge filter

A filter and an intake will also be required.

Brine shrimp are tiny, and they can quickly be drawn into standard fish filters.

As a result, it’s critical to utilize a sponge filter.

The brine shrimp will be able to swim through the sponge, but other organisms will be trapped.

This will keep the water clean and free of bacteria.

Air pump

Artemia will grow more quickly if you provide it with air, which is why an air pump and a sponge filter are required.

Artemia needs access to oxygen and moving water in order to thrive and be healthy.

Heat lamp

Because brine shrimp are cold-blooded, their metabolism slows down when the water is chilly and speeds up when it is heated.

So, a heat lamp is important since it will be used to rapidly raise the temperature of the water.

Ocean salt

Aquarium salt is also needed to help brine shrimp thrive.

It can be purchased at any pet store that sells fish supplies.

2. Properly Place The Shrimp Tanks

Placing the shrimp tank in the right location is important for their well-being.

Here are some tips:

  • Avoid places with temperature fluctuations such as windows, near doors, or outside walls.
  • Avoid places close to an air conditioning or heating vent.
  • Avoid direct sunlight.
  • Find a place close to an outlet.

3. Set Up Brine Shrimp Hatchery

A 2-liter bottle is one of the simplest ways to start a brine shrimp hatchery.

Turn the bottle upside down and cut off the bottom.

Attach the sponge filter inside the container.

You may either pull your air tube in through the bottle’s spout or drill a new hole, depending on the type of sponge filter you are using.

This keeps your baby shrimp and eggs safe from filtration while allowing the sponge to filter your water.

4. Get The Salt Level Correct For Healthy Brine Shrimp

Brine shrimp are saltwater fish. They will not live in freshwater and will not do well in water that is too salty.

So, It is critical to maintain your salt concentration high.

Your brine’s salinity range should be 35 to 40 ppt (or specific gravity of about 1.024 to 1.028).

You can utilize any sort of table salt, rock salt, or other sorts of salts while setting up your hatchery.

However, if you are using ocean salt to create your brine shrimp culture water, the 5-gallon bucket is superior, this will create the best salinity environment for the shrimps.

The sodium chloride in the water will cause the brine shrimp to grow larger, as it creates a more suitable environment for them to develop.

It more closely resembles their natural habitat.

5. Set The Right Acidity To Keep Shrimp Happy

The pH of your water is also important for brine shrimp, it should be between 7.5 and 8 for the best results.

And to do that, there are various commercial products that can be utilized to adjust the pH levels of your hatchery water.

Baking soda, for example, can reduce the acidity of water since it is highly alkaline.

However, you must be careful when adding it, since too much baking soda can also raise the pH level and make it unsuitable for your shrimp.

Sodium hydroxide or peat, on the other hand, can be used to lower the pH of your water if it is too high.

In general, it’s very important to check the pH levels of your hatchery water on a regular basis to ensure that they are in the optimal range for your shrimp.

6. Provide Warm Water For Hatchling Growth

As mentioned before, brine shrimp are cold-blooded creatures and their growth rate is directly related to the water’s temperature.

That’s why providing a heat lamp is so important, as it will help to speed up the process of hatching your eggs and growing your young shrimp.

The warmer the water, the faster they will grow.

As a rule of thumb, the optimum water temperature for a 24-hour complete hatch is 80-82°F.

Although the warmer the water, the less time it will take for the eggs to hatch, it is recommended not to exceed 86°F.

If you’re using a heat lamp, make sure to monitor the temperature on a regular basis until you’ve figured out how far away from the water your heat source should be.

However, if you have a heater, make sure it is set to maintain the water at the correct temperature and doesn’t allow the water to cool too much or heat excessively.

7. Set Up Good Aeration

Brine shrimp need excellent aeration to develop and hatch, therefore, the circulation of water is critical.

If you don’t have adequate circulation, the eggs of your shrimp may not hatch in specific areas of your tank.

Also, it can have a negative impact on your shrimp’s general health.

So, when establishing an effective aeration system, ensure it produces big bubbles to thoroughly aerate the water.

And as a result, the eggs will hatch more evenly and increase the survival rate of your shrimp.

8. Use A Low-Level Light To Grow Quality Shrimp

Low-level light is beneficial when hatching brine shrimp eggs.

It helps to reduce the number of algae that will grow in your hatchery.

On the other hand, too much light will stimulate the growth of unwanted algae in your tank, which can compete with the brine shrimp for food and oxygen.

And this will ultimately result in the death of your shrimp.

9. Have Enough Food To Go Around

Brine shrimp need to eat a lot in order to grow.

And due there are a lot of foods that they like to consume.

They eat phytoplankton, detritus, and other microorganisms. You can also feed them commercial food pellets that are available at most pet stores.

If you’re raising your brine shrimp for food, it’s important to make sure they have enough to eat. You can do this by adding algae or commercial food pellets to their tank on a regular basis.

If you’re not rushing to increase your shrimp population, or if you don’t have a lot of them, feed them every 1-3 days.

10. Keep Your Tank Clean

Tank maintenance is an important part of raising healthy brine shrimp. It’s important to keep the water clean and free of algae.

If you don’t clean your tank, the water will become cloudy and filled with algae. The shrimp will not be able to thrive in these conditions.

It’s important to siphon out any uneaten food or detritus on a regular basis. You should also do a partial water change every week or two.

Make sure to use a good quality water filter to keep the water clean and free of debris.

If you’re using an air stone, make sure to clean it regularly to remove any algae that may have built upon it.

11. Move Adult Brine Shrimp Into The Culture Tank

Once your brine shrimp have reached adulthood, it’s time to move them into the culture tank.

Adult brine shrimp are about 1/2-inch long and they’re a light pinkish color.

You can tell they’ve reached adulthood when their egg sac has turned a deep orange color.

When you’re ready to move them, use a fine mesh net to scoop them up and place them in the culture tank.

Make sure to add some food to the tank so they can start eating right away.

12. Keep The Culture Tank Well-Stocked

The culture tank should be well-stocked with adult brine shrimp so they can continue to reproduce.

If there aren’t enough adult brine shrimp in the tank, they won’t be able to reproduce and you won’t be able to increase your population.

It’s important to make sure the culture tank is well stocked with adult brine shrimp so you can continue to produce new generations of shrimp.

13. Choose The Right Shrimp To Feed Your Fish

Brine shrimp vary in quality as they mature.

Newly hatched shrimps, for example, are high in fat, making up about 23% of their weight.

Adult brine shrimp, on the other hand, is a rich source of protein, they have a protein content of 63 percent.

This makes them an excellent source of protein for fish.

In general, younger fish should be fed a diet that is higher in fat.

Older fish, on the other hand, require a diet with more protein.

14. Clean Equipment After Using Brine Shrimp

Brine shrimp can be a bit messy and they can leave behind a lot of debris.

It’s important to clean your net, siphon hose, and airstone after using them.

This will help keep your tank clean and free of algae.

Brine Shrimp Hatching at Home

The process of hatching brine shrimp is not as difficult as it might seem.

It just takes a bit of time and some basic supplies that can be found at most stores.

Here’s how to do it:


  • Hatchery kit
  • Air pump and accessories
  • 6 mm Airline tubing and check valve
  • Airline manifolds and Micro ball valves: You can use one air pump to run many cultures and manage the air to each with tiny valves.
  • 2 liters plastic bottle: Choose the most robust, solid bottle that will not crush under pressure.
  • Painters tape and a market
  • Measuring devices; you can also use teaspoons
  • RO or Dechlorinated water
  • Baby shrimp eggs
  • Aquarium salt; Still, even though salt is also allowed, rock salt is fine as well, and it is quite inexpensive.
  • Baking soda or Epsom salt
  • Any other appropriate light source that works with incandescent or halogen bulbs, such as a desk lamp or another suitable light source
  • Thermometer
  • Bottle holder or hangers; You can try out your DIY skills on this one.

Step By Step Guide To Hatch Your Brine Shrimp

  1. Use a drill to make a hole in the bottom of the bottle. This will be your air intake.
  2. Set up your air pump. You can do this by using an air pump and tubing, or you can use an air manifold with Micro ball valves. This will allow you to control the amount of air that goes into each hatchery.
  3. Take your 2-liter bottle and cut it in half with a sharp knife. You should make sure that the hole you drilled earlier is on the bottom of the bottle.
  4. Take your painter’s tape and mark off a section in the middle of the bottle that is about 2 inches wide and 6 inches high. This will be your hatchery.
  5. Take your airline tubing and connect it to the air pump. You can use a check valve to keep the water from flowing back into the air pump.
  6. Cut off a section of tubing that is about 6 inches long and put it in your bottle holder or hanger.
  7. Take your hatchery and place it in the bottle. make sure that the hole you drilled is at the bottom of the hatchery.
  8. Take your measuring spoon and add 1 teaspoon of salt to each liter of water you are using. You can also use baking soda or Epsom salt.
  9. Fill your bottle with dechlorinated or RO water. You should make sure that the water is at a temperature of around 78 degrees Fahrenheit.
  10. Add your baby shrimp eggs to the hatchery.
  11. Wait for 24 to 48 hours for the eggs to hatch.

Once the eggs have hatched, you can feed the baby shrimp brine shrimp food, or other appropriate food.


  • You should also change the water in the bottle every two days.
  • If you are using an air pump, make sure to clean the tubing regularly.
  • You can use a desk lamp or another light source to keep the eggs warm.
  • The temperature should be around 80 degrees Fahrenheit.


What Type of Algae Does Brine Shrimp Eat?

Freshwater invertebrates, especially brine shrimp, consume microscopic planktonic algae.

Cultured brine shrimp can be fed with different particulate foods including yeast, wheat flour, soybean powder, or egg yolk.

Do Brine Shrimp Eat Bacteria?

Yes, brine shrimp eat bacteria.

Brine shrimp are filter-feeders that sieve out small organic particles from the water as they swim through it, including microscopic algae and bacteria that are unicellular in nature.

Alternatively, you may powder fish food flakes and sprinkle the dust over the water’s surface.

Shrimp also can be fed on a yeast solution, which is an easy way to provide nutrition.

What’s The Difference Between Sea Monkeys And Brine Shrimp?

The term “brine shrimp” refers to a species of freshwater invertebrates known as sea monkeys.

They’re not brine shrimp as you’d find in nature, but rather Artemia NYOS is a hybrid strain developed in 1957 by Harold von Braunhut.

I Had Many Eggs That Didn’t Hatch. What Should I Do with Them?

The majority of these eggs take a long time to hatch.

Make a fresh batch of saltwater and add the eggs to it.

On the second attempt, they should hatch.

How Long Does It Take Brine Shrimp to Reach Adulthood?

In ideal circumstances, nauplii develop rapidly and mature in 3 weeks.

The adults are approximately 8 millimeters long, although they can reach up to nearly double that length.

How Can I Tell If My Brine Shrimp Are Healthy?

Examine the culture for signs of disease. If the shrimp concentrate in the light, they are healthy.

Also, examine the digestive system (the straight tube running down the length of a shrimp’s body) if they don’t and you have access to a dissection scope. It should be filled with food if not—feed them.

Can I Refrigerate Brine Shrimp?

Yes. They may be kept in the refrigerator for several days (not frozen) and refrigerated.

Make sure before placing them in the fridge, that you have fed them for a few hours.

Why Are My Brine Shrimp Dying?

They might be overcrowded.

If this is the case, split the culture up. As there may be a lack of aeration, or you could be using a wooden air stone or another type of air stone that creates a fine “mist” of bubbles.

That is because small bubbles from the airstone can obstruct the shrimp’s feeding system and cause them to starve.

Last Words

Now that you know how to grow brine shrimp, you can enjoy watching them grow and thrive in your own aquarium.

Not only are they a beautiful addition to any tank, but they are also an excellent source of food for fish.

By following these simple steps, you can have a thriving hatchery of brine shrimp in no time!
