A Guide to Hatching Artemia with Over 90% Success
A step-by-step hatching guide — from water preparation and egg density to effectively harvesting nauplii.
Preparing the Hatching Water
Use filtered saltwater with a recommended salinity of around 25–30‰. Keep the water temperature stable between 28–30°C, with gentle, continuous aeration.
- pH: 7.5 – 8.5
- Maintain lighting throughout the hatching process
- Egg density per Diamond's product-specific guidelines
The Hatching Process
Soak the eggs for the recommended duration and avoid letting them settle at the bottom. With Diamond's high-quality Artemia eggs, hatch rates can exceed 90%.
Keep backup water with matching parameters ready to avoid interruptions when refreshing the hatching batch.

Harvesting and Use
Turn off aeration to let shells float, then concentrate the nauplii using a separator per the equipment instructions. Rinse thoroughly before feeding.
