  1. Storage HR indicates the hatch rate of the eggs during the storage in water. Final HR also includes the hatch rate of the eggs at the end of the period of water storage, after immersion in a bacterial broth solution. R indicates the Pearson correlation coefficient between hatch rate and storage duration, and P the significance of the correlation (*P<0.05, **P<0.001 and ***P<0.0001)
