Instant Zooplankton® – Brine Shrimp Eggs

Not all GSL Artemia (Brine Shrimp Eggs) are the same quality. What one company may label as 90% may be equivalent to another company's 75%. The true measure of quality is the nauplii per gram (NPG) count and not simply a hatch rate designation. Our GSL Artemia have hatch rates and NPG counts as shown below.
