What Do You Need to Keep Brine Shrimp Alive?: The Definitive Guide
Keeping brine shrimp alive requires providing them with the correct salinity, oxygen levels, food, lighting, and temperature. This guide will delve into each of these crucial aspects, ensuring your brine shrimp thrive.
Introduction: The Tiny Titans of the Aquatic World
Brine shrimp, scientifically known as Artemia, are small crustaceans that inhabit saltwater environments worldwide. They are incredibly resilient creatures, able to withstand extreme salinity levels that would kill most other aquatic life. This hardiness makes them a popular choice for aquaculture, aquarium hobbyists, and even educational projects. However, despite their resilience, what you need to keep brine shrimp alive is a carefully controlled environment that mimics their natural habitat. Success hinges on understanding and providing the right conditions for their survival and growth. This article provides a comprehensive guide to achieving just that.
The Fundamentals: Creating the Right Environment
The key to successfully raising brine shrimp is understanding the factors that contribute to their well-being. These can be broadly categorized into water quality, feeding, and environmental conditions. Neglecting even one of these areas can lead to high mortality rates.
Water Quality: The Foundation of Life
- Salinity: Brine shrimp thrive in saltwater environments, typically ranging from 1.010 to 1.026 specific gravity. Using a hydrometer or refractometer is essential to accurately measure and maintain the correct salinity.
- pH: Maintain a pH level between 7.5 and 8.5. Baking soda can be used to increase pH if needed, but gradual adjustments are crucial.
- Oxygen: Adequate oxygen levels are vital. Use an air pump with an air stone to aerate the water. Overcrowding can quickly deplete oxygen levels.
- Water Changes: Regular partial water changes (10-20% every week) help remove waste and maintain water quality. Use aged saltwater for these changes.
Feeding: Nourishment for Growth
- Algae: Brine shrimp primarily feed on microscopic algae. You can either grow your own algae cultures or purchase commercially available algae suspensions.
- Yeast: A small amount of baker’s yeast can be used as a supplementary food source. However, overfeeding yeast can quickly foul the water.
- Flour: Very finely ground wheat flour can also be used sparingly as supplemental food. Ensure it is extremely fine to prevent clogging the brine shrimp’s feeding appendages.
- Feeding Schedule: Feed small amounts 2-3 times per day, ensuring the water clears between feedings. Overfeeding is a common mistake.
Environmental Conditions: Temperature and Light
- Temperature: The ideal temperature range is 75-85°F (24-29°C). A heater may be necessary to maintain this range, especially in colder climates.
- Light: Brine shrimp need light for optimal growth and development. Indirect natural light or a fluorescent lamp is sufficient. Avoid direct sunlight, which can overheat the water.
Step-by-Step Guide to Raising Brine Shrimp
- Prepare the Hatching Tank: Clean and disinfect a suitable container (e.g., a glass or plastic aquarium).
- Prepare the Saltwater: Mix non-iodized salt with dechlorinated water to achieve a specific gravity of 1.010-1.026.
- Aerate the Water: Place an air stone at the bottom of the tank and connect it to an air pump.
- Add Brine Shrimp Eggs: Sprinkle brine shrimp eggs evenly over the surface of the water. Use a reputable brand for best hatching results.
- Maintain Temperature and Light: Place the tank in a location with adequate light and maintain the temperature within the ideal range.
- Monitor and Feed: Observe the tank for hatching. Once hatched, begin feeding the nauplii (baby brine shrimp) with algae or yeast.
- Perform Water Changes: Regularly perform partial water changes to maintain water quality.
Common Mistakes to Avoid
- Overfeeding: This is the most common mistake. Overfeeding leads to a build-up of waste and a depletion of oxygen.
- Inadequate Aeration: Insufficient aeration leads to low oxygen levels, which can suffocate the brine shrimp.
- Poor Water Quality: Neglecting water changes and failing to maintain proper salinity and pH can create an unsuitable environment.
- Temperature Fluctuations: Rapid temperature changes can stress and kill brine shrimp. Maintain a stable temperature.
- Using Iodized Salt: Iodized salt is toxic to brine shrimp. Always use non-iodized salt.
Troubleshooting
- Low Hatch Rate: This could be due to old or poor-quality eggs, improper salinity, or incorrect temperature.
- High Mortality Rate: This could be due to poor water quality, overfeeding, inadequate aeration, or temperature fluctuations.
- Slow Growth: This could be due to insufficient feeding or inadequate lighting.
Important Considerations
- Egg Quality: The quality of the brine shrimp eggs directly impacts hatch rates and the vitality of the nauplii. Source eggs from a reputable supplier.
- Water Source: Use dechlorinated water. Tap water contains chlorine and chloramine, which are harmful to brine shrimp. Let tap water sit out for 24 hours to dechlorinate, or use a dechlorinating product.
- Cleaning: Regularly clean the tank to remove debris and prevent the buildup of harmful bacteria.

Frequently Asked Questions (FAQs)
What is the best type of salt to use for brine shrimp?
Non-iodized salt is crucial for successfully raising brine shrimp. Iodized salt contains iodine, which is toxic to these crustaceans. Sea salt mixes designed for saltwater aquariums are generally a good choice as they provide the necessary trace elements.
How often should I feed my brine shrimp?
Feeding frequency depends on the density of the population and the type of food. Generally, feeding 2-3 times per day in small amounts is sufficient. The water should clear between feedings to prevent overfeeding and water fouling.
What type of food is best for brine shrimp?
Microscopic algae is the ideal food source for brine shrimp. However, baker’s yeast or very fine wheat flour can be used as supplemental foods. Commercially available brine shrimp food is also a convenient option.
How much light do brine shrimp need?
Brine shrimp need sufficient light for optimal growth and development. Indirect natural light or a fluorescent lamp is sufficient. Avoid direct sunlight, which can overheat the water.
How do I dechlorinate tap water for brine shrimp?
There are two main ways to dechlorinate tap water. You can let the water sit out for 24 hours, allowing the chlorine to naturally dissipate. Alternatively, you can use a dechlorinating product specifically designed for aquariums. These products neutralize chlorine and chloramine instantly.
What is the ideal temperature for brine shrimp?
The ideal temperature range for brine shrimp is 75-85°F (24-29°C). Maintaining this temperature range is crucial for optimal hatching, growth, and survival.
How often should I do water changes for brine shrimp?
Regular partial water changes are essential for maintaining water quality. Perform a 10-20% water change every week. Use aged saltwater for these changes to avoid shocking the brine shrimp.
How long do brine shrimp live?
The lifespan of brine shrimp varies depending on environmental conditions, but they typically live for several months. Providing optimal conditions will maximize their lifespan and reproductive potential.
What is the best way to aerate a brine shrimp tank?
Using an air pump with an air stone is the most effective way to aerate a brine shrimp tank. Place the air stone at the bottom of the tank to ensure adequate oxygen distribution throughout the water.
What salinity level is ideal for brine shrimp?
The ideal salinity level for brine shrimp is 1.010 to 1.026 specific gravity. Use a hydrometer or refractometer to accurately measure and maintain the correct salinity.
What should I do if my brine shrimp are dying?
If your brine shrimp are dying, immediately check the water parameters (salinity, pH, temperature). Perform a partial water change and ensure adequate aeration. Investigate potential causes, such as overfeeding or poor water quality.
Can I keep brine shrimp in a small container?
While brine shrimp can survive in small containers, larger containers are generally better as they provide a more stable environment. Regardless of size, proper water quality and aeration are essential.
