卤虫卵脱壳与孵化规程
标准化实验室操作程序，旨在实现无节幼体产量和生物安全的最大化。
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.

存储与物流
存放于阴凉干燥处。开罐使用后请重新密封，以维持防潮效果。
Why buyers choose this line
No hatching step at all
Shell-free cysts feed directly, which removes the incubation cones, the separation step and the labour that goes with them.
Improved biosecurity in larval systems
No shell means no shell debris in the tank and one less contamination route into a larval system.
Full energy retained
Nothing is spent on hatching, so the energy the nauplius would have used reaches the larvae instead.
Predictable dosing
A dry, moisture-controlled product doses to a known weight rather than to a variable hatch.

丰年虫孵化方案
查阅逐步的科学孵化参数——盐度标准（25-35 ppt）、温度上限（28-30 °C）及孵化锥设置——以获得稳定高产的丰年虫无节幼体。丰年虫直接投喂鱼虾幼体，是与轮虫培养不同的阶段。
