Artemia Decapsulation & Hatching Protocol
Standard laboratory operating procedures for maximum nauplii yield and biosecurity.
Prepare Incubation Solution
Prepare a saline solution using sea salt at 28–30 ppt (g/L) or UV/ozone treated filtered seawater. Adjust pH to 7.9–8.5 (add 2 g Sodium Bicarbonate NaHCO₃ per liter if pH is lower). Maintain water temperature at 27–29 °C.
Prepare Decapsulation Solution
Standard ratio for 454 g (1 lb) of dry cysts: use 1.5 L Sodium Hypochlorite (NaOCl - 10% active chlorine) combined with 34–50 ml saturated NaOH solution.
Hydration Phase
Place dry Artemia cysts in clean freshwater under strong aeration for 1 hour at 20–25 °C. Hydration is complete when cysts change from biconcave disk shape to fully spherical.
First Decapsulation Bath
Transfer hydrated cysts into 0.75 L of decapsulation solution. Stir continuously for 25–40 minutes until the outer brown shell dissolves and turns bright orange.
Separation & Washing
Immediately strain the decapsulated embryos through a 125 µm sieve mesh and rinse thoroughly with clean tap water or seawater to remove residual chlorine.
Second Decapsulation (Optional)
If shell fragments remain, perform a brief 3–5 minute secondary wash bath in diluted NaOCl solution before final rinsing.
Chemical Dechlorination & Activation
Neutralize active chlorine by dipping strained cysts into a 0.1% sodium thiosulfate (Na₂S₂O₃) or ascorbic acid solution for 1 minute.
Conical Reactor Incubation
Transfer activated cysts into a conical hatching vessel filled with 28–30 ppt seawater at 28–30 °C. Provide continuous bottom aeration and 2,000 Lux continuous light for 20–24 hours.
Harvesting & Nauplii Collection
Turn off aeration for 10–15 minutes. Empty shells float to the surface while live phototactic nauplii concentrate at the bottom light source for easy siphoning.
Key Applications
- Marine finfish larvae (sea bass, sea bream, grouper)
- Shrimp post-larvae
- Ornamental fish larvae
- Home aquariums & reef tanks
- Public aquariums & pet shops
Store below 4 °C. Vacuum-sealed cans remain viable for up to 36 months.
Premium Artemia cysts (brine shrimp eggs) selected for high hatchability, small nauplii size, and high energy content. The global benchmark for hatchery live feed.
CPG (Number of Cyst per Gram) varies with size and genus of Artemia and is not a quality indicator on its own. Quality is defined by Hatching Rate and by the nutritional value and biomass of the resulting nauplii.
We guarantee superior product quality and consistency, with a stable hatching rate of at least 85% verified on every batch before dispatch.
Frequently Asked Questions
Technical parameters, storage, biosecurity, and hatchery protocols for Artemia Cysts.
Artemia Hatching Protocol
Access step-by-step scientific incubation parameters — salinity standards (25–35 ppt), temperature limits (28–30 °C), and hatching-cone setup — for consistent, high-yield Artemia nauplii. Artemia is fed directly to fish and shrimp larvae, a separate stage from rotifer culture.
