Brine Shrimp Eggs Hatching Instructions

• Hatching tank: Use a clear plastic or glass bottle. For larger quantities, use a 10-55 gal. (38-208 L) fiberglass tank.
• Use clean seawater or artificial saltwater with a specific gravity of 1.01 to 1.02.
• The optimum pH is 7.5-8.5. If necessary, add an alkaline solution made from soda ash or sodium sulfate to raise the pH.
• During hatching, use sufficient aeration to keep all eggs in circulation at all times. Pump the air through an airstone to get a smooth flow.
• The optimum hatching temperature is 82-85°F (28-29°C).
• Most hatching will occur after 20-36 hours.
• To harvest, remove the air supply and wait 10-15 minutes. The nauplii will school on the bottom. Siphon them into a fine mesh net by using a plastic tube.
• Store cysts in a cool, dry place. For maximum preservation, cysts can be frozen.
