Title:
METHOD TO HATCH FREE SWIMMING NAUPLII FROM ARTEMIA CYSTS
Document Type and Number:
WIPO Patent Application WO/2008/022569
Kind Code:
A1
Abstract:
A method to hatch free swimming nauplii from Artemia cysts, including incubating the cysts in a hatching medium, in which the cysts are introduced simultaneously with a compound comprising one or more o-hydroxylphenyl structures, as an additive. The additives contain at least one substance selected from the group composed of pyrogallic acid, methyl gallate, tannic acid, vegetable tannin extract, tea polyphenol, apple polyphenol, pine bark extract and so on. A weight ratio of the cysts and additives is 100:0.5~4. The method achieves about 90% of the hatching percentage of the cysts in 24 hours by breaking diapause of said diapauzing cysts with said additives. The additives, which have a flocculent effect, enable free swimming nauplii to separate easily from incompletely incubating Artemia cysts. The coverage of hatching medium can be expanded, especially for hatching of Artemia cysts from an inland salt lake.
