How to culture brine shrimp

---

Culturing brine shrimp is a straightforward process commonly done to provide a live food source for aquarium fish and other aquatic organisms. Here's a simple step-by-step guide:

Materials Needed:

• Brine shrimp eggs
• Non-iodized salt (marine salt or aquarium salt)
• Aeration system (air pump and air stone)
• Light source
• Container with a lid
• Fine mesh net or brine shrimp hatchery

Steps:

Prepare Saline Solution:

• Mix non-iodized salt with water to create a saline solution. The recommended concentration is around 25-35 grams of salt per liter of water. Use a hydrometer or refractometer to measure salinity.

Add Brine Shrimp Eggs:

• Introduce brine shrimp eggs to the saline solution. Use the recommended amount specified by the manufacturer. Brine shrimp eggs are typically sold with instructions on the packaging.

Aerate the Solution:

• Set up an aeration system using an air pump and air stone. Brine shrimp require continuous gentle aeration to keep them suspended in the water and ensure proper oxygenation.

Provide Light:

• Place the container in a well-lit area or provide artificial light. Brine shrimp eggs hatch faster in the presence of light. A 24-hour light cycle is commonly used during the initial stages of the culture.

Wait for Hatching:

• Brine shrimp eggs typically hatch within 24 to 48 hours. Monitor the container for the appearance of tiny brine shrimp nauplii (larvae). They will swim towards the light.

Harvesting:

• Once the brine shrimp nauplii are visible, you can start harvesting them. Use a fine mesh net or a brine shrimp hatchery to collect the nauplii while leaving the unhatched eggs and empty shells behind.

Feed to Aquarium Inhabitants:

• Rinse the harvested brine shrimp nauplii with fresh water to remove excess salt. Feed them to your aquarium fish or other aquatic organisms. Brine shrimp provide a nutritious live food source.

Maintain the Culture:

• To maintain the culture, repeat the process by adding fresh brine shrimp eggs to the saline solution. Continue to aerate and provide light for optimal hatching.

Regular Water Changes:

• Consider periodic water changes to maintain water quality. You can siphon out a portion of the culture and replace it with fresh saline solution.

Adjust Salinity:

• Periodically check and adjust the salinity of the solution as needed. Ensure that it remains within the recommended range for brine shrimp.

Culturing brine shrimp is a continuous process, allowing you to have a consistent live food source for your aquarium. Adjustments to aeration, lighting, and salinity may be needed based on your specific conditions and the growth of the brine shrimp.
