Title:
アルテミア休眠嚢子の孵化率を増加させる方法
Document Type and Number:
Japanese Patent JP5525159
Kind Code:
B2
Abstract:
A method to hatch Artemia nauplii starting from an amount of Artemia cysts, including diapauzing cysts, by incubating the cysts in a hatching medium under conditions allowing at least a portion of the cysts to hatch and to release free swimming nauplii within a predetermined incubation period, in which method the cysts are brought in contact with a compound comprising at least one -(OH)C=C(OH)- structure, to break diapause in at least a number of said diapauzing cysts in order to enable them to produce free swimming nauplii within said predetermined incubation period thereby increasing the hatching percentage of the incubated cysts from X % of the total number of full cysts when the cysts are not brought in contact with said compound, to a hatching percentage higher than X % when they are brought in contact with said compound. An advantage of bringing compounds comprising at least one -(OH)C=C(OH)- structure, in contact with diapauzing cysts is that the range of optimal concentrations of said compound is very broad, so that lethal effects on Artemia will not often occur, even when double or triple amounts of the optimal concentration is applied.
