Hey there! If you’re wondering whether brine shrimp need salt water, let me cut to the chase – yes, they absolutely do! These tiny critters can’t survive without it. But there’s way more to the story than just that simple answer. I’ve spent years raising brine shrimp, and I’m excited to share everything I’ve learned about keeping them happy and healthy.
Why Salt Water is Non-Negotiable for Brine Shrimp
Brine shrimp have evolved to live specifically in super salty environments. Here’s why they need salt water to survive:
- Their bodies are specially designed to handle high salt levels
- They use salt for important stuff like digesting food and moving their muscles
- Without salt water, they basically dehydrate and die pretty quickly
- They can’t regulate their body’s water balance in fresh water
Getting the Salt Levels Just Right
In my experience hitting the sweet spot with salt levels is super important. Here’s what you need to aim for
- Ideal salt concentration: 25-40 parts per thousand
- Perfect specific gravity: 1.018 – 1.025
- Quick recipe: 1 cup marine salt per gallon of water
Pro tip: I always start with 1.020 specific gravity – it’s like the Goldilocks zone for brine shrimp!
What Kind of Salt Should You Use?
Not all salt is created equal! Here’s what works best:
Best Options:
- Marine salt mix (my top choice)
- Aquarium salt
- Non-iodized salt (in a pinch)
Avoid These:
- Table salt (contains harmful additives)
- Iodized salt
- Rock salt
Setting Up Your Brine Shrimp Habitat
Here’s my tried-and-true setup for keeping brine shrimp:
-
Container Shape
- Use cone-shaped or V-bottom containers
- Avoid flat-bottom tanks
- Keep it transparent for easy monitoring
-
Water Parameters
- Temperature: 26-28°C (80-82°F)
- pH: 8.0 or higher
- Good aeration is crucial
-
Additional Requirements
- Decent lighting (helps with hatching)
- Regular water changes
- Clean equipment
Common Problems and Solutions
Sometimes things go wrong. Here’s what I’ve learned about fixing common issues:
When Salt Levels Are Too High
- Shrimp become sluggish
- Reduced reproduction
- Possible death
Quick Fix Slowly dilute with properly prepared salt water until reaching correct levels
When Salt Levels Are Too Low
- Shrimp look stressed
- Swimming problems
- Quick death if not corrected
Quick Fix: Add marine salt mix gradually while monitoring with a hydrometer
Feeding Your Brine Shrimp
Even with perfect salt levels, they need proper nutrition:
- Feed 2-3 times daily
- Use quality microalgae
- Supplement with:
- Spirulina powder
- Yeast
- Egg yolk
Tips for Success
After lots of trial and error, here are my top tips:
- Always test salinity before adding shrimp
- Keep equipment clean
- Make changes gradually
- Monitor water quality regularly
- Don’t overcrowd your container
FAQs About Brine Shrimp and Salt Water
Q: Can brine shrimp survive in regular tap water?
Nope! They’ll die within hours in fresh water.
Q: How long can they live in the wrong salt levels?
Not long – maybe a few hours in low salt, even less in fresh water.
Q: Can I use ocean water?
Technically yes, but I wouldn’t recommend it due to pollutants and inconsistent composition.
The Bottom Line
Brine shrimp absolutely need salt water – it’s not optional! They’re fascinating creatures that have evolved to thrive in salty environments. With the right setup and care, they’re actually pretty easy to keep. Just remember: proper salt levels, good food, clean water, and you’ll have happy, healthy brine shrimp!
Remember, these little guys have been around for millions of years, surviving in some of Earth’s saltiest places. The least we can do is give them the salty home they need!

Great crustaceans! Does more or less salt in the water create super shrimp? Make your own seawater and discover how salt helps or hinders hatching.
Brine shrimp are tiny crustaceans that live in salt water. This means that they’re related to crabs, lobsters, and other shrimp. However, brine shrimp are much smaller than other shrimp, and they make intriguing pets. In this experiment, you’ll see how different amounts of salt change the hatching rates of brine shrimp.
The ocean and some lakes are salty, and this salt comes from the rocks in the water. You can’t see the salt in the water because it is dissolved, but it has a big impact on the creatures that can live in an environment. The amount (or concentration) of salt in the water is called salinity.
Brine shrimp have an interesting life cycle. The adult shrimp lays cysts that contain baby shrimp. These cysts have a superpower: if conditions in the environment are bad, they will stay dormant for a while and wait until conditions improve before they hatch.
For this experiment, you’ll get three different containers and make them each into a different ocean. Create a hypothesis, your best guess as to what is going to happen. Will the brine shrimp prefer water that’s very salty, somewhat salty, or not very salty?
What is the ideal salinity for hatching brine shrimp?
- Three clear, one quart plastic containers
- Three quarts of distilled water
- Tablespoon
- Four tablespoons of aquarium salt
- ¾ tablespoon brine shrimp eggs
- Teaspoon
- Wooden spoon
- Magnifying glass or microscope
- 3 petri dishes
- Notepad
- Pencil
- Fill each container with a quart of warm distilled water.
- Get your aquarium salt, and stir half a tablespoon of salt into the first container, one tablespoon into the second, and two tablespoons into the last. Label the containers.
- Stir until the salt is dissolved, and check for crystals on the bottom before you go on.
- Now it’s time to add the baby shrimp! Stir in a quarter tablespoon of eggs in each container.
- Put the containers on a sunny window ledge or under a light. Make sure that the water stays warm, but not too hot. It should be room temperature. Why is the room light and at room temperature important?
- Gently stir the water every few hours. Why do you need to stir the water?
- Over the next two days, watch the baby shrimp hatch. Take notes about the progress in each container.
- After 48 hours, take a teaspoon-sized sample from each container, and place the sample in a small, clear container such as a petri dish.
- Look at each sample with your magnifying glass and see how many shrimp have hatched. If you have a microscope, this is a good time to use it, because you’ll be able to see the shrimp babies very clearly.
- Go back the next day and take another sample. Which container has the most baby shrimp?
Brine shrimp do best at a salinity of 1 2/3 tablespoons of salt per quart of water.
Before it is born, a brine shrimp lives in a cyst. When conditions are right, the babies will hatch. These babies are called nauplii. If conditions are bad, the females release dormant cysts. These cysts don’t turn into babies and hatch until the conditions are good. That way, the nauplii will have the best chance of survival.
What makes brine shrimp happy? Shrimp develop at different rates depending on the conditions around them. They like to have lots of oxygen in the water – you added oxygen when you stirred the solution. They also like to have a temperature that’s not too hot and not too cold. Of course, the food needs to be good too: brine shrimp use their bodies to move tiny, microscopic organisms into their mouths.
Brine shrimp also need saltwater. They are tough and can handle very different amounts of salt. Salinity is usually measured in parts per thousand (ppt), which means the number of grams of salt in a kilogram of liquid. Brine shrimp do best at a salinity of nearly 2 tablespoons of salt per quart of water. However, whether they grow and reproduce well depends on all of the other factors in their environment as well.
Depending on the conditions of the place where they live, it can take as little as a week or a many as six weeks for the babies to turn into adults.
Scientists in labs use brine shrimp to test for pollution in water. Many animals like birds eat small animals that live in the water. If the water is polluted, the shrimp may not be as successful, or they may die. You can try other experiments using tiny amounts of cooking oil or dish soap to see how brine shrimp hatching rates change when there is pollution in the water.
What other environmental conditions might change how brine shrimp hatch and grow? How else could you make the best home for your brine shrimp?
