  • Cost reduction and time saving with no decapsulation required

Artemia Cysts are Brine Shrimp eggs with an excellent hatching rate. Artemia Cysts nauplii are well-known as the ideal live food for the first stages of larval shrimps. It is important to feed Artemia nauplii as soon as possible after hatching to take full advantage of the stored reserves found in freshly hatched nauplii.

Instructions for use

Keep cysts at room-temperature (20-24°C) 24 hours prior to hatching.
Hatching water: Use clean seawater or fresh-water containing 28-30 g of salt (NaCl). PH should be 8.0-8.5. If the PH is below 8.0 add Sodium-bicarbonate at 1.5 g/l.

Before hatching the cysts add 0.5-0.6 ml of Hydrogen Peroxide (H2O2) to the hatching water.

Use a clean tank with conical-shaped bottom. Shake well with cysts before use. Do not wash cysts.
Add 2 g of cysts per liter. Keep the temperature constant at 28°C. Ensure light-intensity at 2,000 lux. Foresee enough aeration to keep the cysts in suspension.

After 24h stop aeration, wait 5 minutes and siphon the nauplii from the bottom of the tank, rinse with clean water and feed.
