Brine Shrimp (Genus Artemia) in the Aquarium

Whether you want to breed Brine Shrimp or use brine shrimp for your fish food, we will explore everything you would like to know about this fascinating Aremia Saline Shrimp that has existed since the Triassic period. 

They have perhaps lasted so long as they avoid most types of predation, such as fish, because they live in waters of extreme high salinity: up to 25% (250 parts per thousand).

Yes they are known as Sea Monkeys and are a great gift for children – but they also have another, much larger, role in the aquarium industry.

Why is Brine Shrimp SO popular?

The main reason – Brine Shrimp is one of the best fish food fish can eat! And interestingly humans as well. You may like to try some sometime. The type of shrimp used for food is called nauplii and raising brine shrimp is a interesting hobby.

However for small fish and fry – decapsulated brine shrimp eggs is even more amazing for accelerating the growth of these fish.

The reason? Highly bio-available proteins. In particular, the amino acid profile is high in alpha amino acids. An index called The Protein Digestibility Corrected Amino Acid Score, is 1 Out of 1 – so that must be pretty good.

It comes down to the fact your fish will grow much larger eating Brine Shrimp vs other foods.

Brine shrimp anatomy

“Brine shrimp have a head, middle (thorax) and a tail (abdomen). They usually move around on their backs, upside down with their flat-legs above. The eleven pairs of flat-legs are used as filters, paddles, and as gills. On the front of the head are three black eyes.” – https://en.wikipedia.org/wiki/Brine_shrimp

So take wikipedia’s word for it – shrimp move upside down and have an extra eye in addition to their compound eyes!

A hard exoskeleton covers the entire body and they generally grow to be 15mm long.

Creating a brine shrimp Ecosphere

Rather than producing shrimp for food, another popular hobby using Brine Shrimp is to create a little Earth that simply runs on sunlight and maintains itself! You may also see the product called “Sea-monkey’s”. This is a Brine Shrimp Eco-sphere!

DIY ecosystems aren’t awfully hard to get up and running, but it does require some fairly in-depth knowledge. There are many concepts involved, however, it can be a very rewarding pursuit.

Brine shrimp water parameters

Brine shrimp die quickly in fresh water, and have some other particular parameters we must account for in the fish tank, or ‘shrimp tank’.

Salinity: Approx.y 1.5 tablespoons of salt per quart (or liter) of water to achieve the correct salt concentration. Table salt may be used.

Water Quality: Only use tap water if you can add PRIME to the water to clear the chlorine.

pH: For hatching brine shrimp alkaline water is required. A pH of 8.0 or higher is recommended. 

If pH of your water is 7 or lower (ie. tap water), use baking soda at the rate of 1/2 a teaspoon per liter.

Aeration: Aeration is necessary to keep cysts floating provides sufficient oxygen for the cysts to have healthy cells.

Stocking Density: 1 gram per liter / half a level teaspoon of cysts per liter is a good level.

Temperature: Optimum water temperature for a 24 hour complete hatch is 27 Degrees Cs within a range of 1 degree.

Light: Illumination is not required.

How to Culture Brine Shrimp

Brine shrimp facts

  • Females tend to be larger than males.
  • Brine shrimp circulatory and respiratory systems work together to remove extra salt from their body and distribute oxygen.
  • They breathe through gills on their feet.
  • Like humans, Brine shrimp have a protein called hemoglobin in their blood. They need hemoglobin because oxygen levels can be very low in salty water.
  • Then, the shrimps gills & glands pump out the excess salt, and carbon dioxide.
  • They move by beating their tails and by the continuous movement of the legs along their body.

Brine shrimp facts egg facts

  • .Adult female brine shrimp ovulate about every 140 hours. In favourable conditions, the female brine shrimp can produce eggs that almost immediately hatch. 
  • In extreme conditions, such as low oxygen level or salinity above 150‰, female brine shrimp produce eggs inside cysts.
  • Cysts are metabolically inactive and can remain in total stasis for two years in dry oxygen-free conditions, even at temperatures below freezing. While in cysts, brine shrimp eggs survive temperatures of liquid air (−190 °C) and a small percentage survive above boiling temperature (105 °C or 221 °F) for up to two hours.
  • Once placed in normal briny (salt) water, the eggs hatch within a few hours. The nauplius larvae are less than 0.4 mm in length when they first hatch. Brine shrimp have a biological life cycle of one year 

Brine shrimp alternative as a food source

At commercial quantities, many look for alternatives as the word shrimp supply can be unstable. Shrimp naturally occur in about salt ponds & lakes around the world and the Mediterranean area however primarily the supplies come from one place, the Great Salt Lake in Utah, USA. 
The GSL provides between one-third and one-half of global supplies – can be significantly affected by various natural phenomena like variations in the salinity and water level in the lake.
For aquarium fish keepers, there is no equivalent quality food for small fish,  period.

Breeding with Brine shrimp eggs

If you are looking into Breeding Brine Shrimp for fish food you have made an intelligent investment. The initial outlay in time and money will be recouped by not spending on fish food – and it is an interesting endevour.  

Fully grown brine shrimp will take all of three weeks to mature from babies to the adult stage, a very fast rate of growth!

There are critics when it comes to growing your own fish food (suppliers claiming the process is difficult) at NanoTanks Australia we like to not just sell you the food and act like its hard. We would rather spend our time furnishing our tanks with great pet fish than selling fish food.  

The counterpoint to this argument is for specialty mixes and in this case it is better to buy brine shrimp eggs from us as they are decapsulated enabling easy digesting.

And to breed properly we recommend you buy Brine Shrimp Hatchery rather than DIY.

Do you have a Brine shrimp hatchery for sale?

Yes we do, the Brine shrimp hatchery for producing live Brine Shrimp. We trust the the JBL Artemio for creating a positive breeding experience.

The Hatchery It is funnel-shaped with a lid, and can be wall mounted. 

Baby brine shrimp vs decapsulated brine shrimp egg

Some people recommend your fish eat the baby shrimp. If you are growing shrimp yourself this is a great food source! If you are not growing your own why not just buy the decapsulated egg it is superior in nutrients and is just as digestible without the shell.  

Brine shrimp eggs for sale Australia

These eggs are available from most aquarium shops in Australia. Our decapsulated eggs are available here.

Brine shrimp for betta fry?

Of particular note Betta fry does extremely well with the high protein diet, creating a larger Betta than you would otherwise expect!
