Vanhaecke, P.; Sorgeloos, P. (1982). International study on Artemia : 18. The hatching rate of Artemia cysts : a comparative study. Aquacult. Eng. 1: 263-273

A comparative study has been carried out on the hatching rate of Artemia cysts of different geographical origin and on different batches of the same source. Substantial variation, among as well as within geographical strains, indicates that the hatching-rate criterion is not strain specific. In an attempt to identify the parameters which influence the hatching rate, it was found that the cyst-drying technique as well as the storage conditions may significantly affect this criterion. It has also been demonstrated that the cysts' hatchability is influenced by their previous drying and storing conditions. Optimal hatching results are guaranteed when a fluidized bed dryer is used and the cysts are stored under vacuum or nitrogen.
