Frozen Decapsulated Artemia Cysts

Artemia (brine shrimp cysts) are a critical live feed in shrimp, marine finfish, and ornamental hatcheries worldwide.
Traditional cysts require labor-intensive decapsulation and careful hatching management.
A major breakthrough is now reshaping hatchery workflows: Frozen Decapsulated Artemia.

This innovation delivers higher biosecurity, simpler handling, and greater operational consistency.
Most importantly, once cysts are decapsulated, they can be frozen at –18°C and stored for up to
two years without compromising quality.

Product Overview & Technical Highlights

Result of Decapsulated Artemia Cysts

20 hours 15.36 kg

24 hours 19.3 kg

Advanced Biosecure Decapsulation Technology

Using a precision-controlled biochemical process, eggshells are removed
without affecting hatching performance.
After decapsulation, Vibrio and surface bacteria are eliminated,
significantly reducing contamination risk and improving hatchery biosecurity:

• Zero Vibrio contamination
• Cleaner rearing environments
• Healthier, more robust larvae

This level of biosecurity is a major advantage for shrimp and marine fish hatcheries where early-stage mortality is often linked to bacterial presence.

Key Advantages of Frozen Decapsulated Artemia

1. High Hatching Rate (Up to 90%)
   Even after shell removal, cysts retain strong hatch performance—delivering consistent output across hatch cycles.
2. Direct-to-Hatch Convenience
   Take directly from the freezer into the hatching tank and aerate as normal.
   No chemical treatment, no washing, no extra steps—saving labor and reducing human error.
3. Exceptionally Clean Nauplii
   Harvested nauplii are clean, uniform, vigorous, and easy to collect—free from shells and debris.
4. 100% Feedable for Larval Rearing
   Newly hatched nauplii and unhatched decapsulated cysts can be fed directly, improving digestibility and reducing indigestion risk from shell fragments.
5. Long-Term Frozen Stability
   Fully stable and viable for up to two years at –18°C, supporting supply planning and consistent production.

Recommended Hatching Conditions

For optimal results, use the following parameters:

• Temperature: 27–30°C
• Salinity: 20–30 ppt
• Illumination: >2000 lux
• Density: 1 kg per 400–450 L
• Aeration: Secure the aeration tube at the center bottom of the tank

Post-Hatching Guidelines

• Maintain hatching conditions for an additional 24 hours.
• Stop aeration to allow the water to become still.
• Discharge remaining cysts from the bottom outlet.

Setting a New Benchmark in Global Hatchery Feed Standards

Frozen Decapsulated Artemia is not just an improvement—it is a transformative advancement for aquaculture.
With superior cleanliness, high biosecurity, and streamlined usability, it is positioned to become the new global benchmark for hatchery live feed standards.
