What is the general rate of empty shells of brine shrimp eggs

The empty shell rate of brine worm eggs is affected by factors such as temperature, production process, species differences and quality testing. Within the appropriate temperature range, the higher the temperature, the higher the hatching rate. Improper production process, such as screening is not strict, cleaning is not clean, disinfection time is too long or the temperature is too high, increase the empty shell rate. Quality testing is not strict, such as inaccurate testing methods, improper handling of unqualified products, resulting in an increase in the rate of empty shells.
