The invention relates to a Decapsulated artemia egg preparation method improving the hatching rate, and belongs to the technical field of artemia eggs. The decapsulated artemia egg preparation method improving the hatching rate includes the steps: taking haw as the raw material, juicing the haw, and performing dydration on artemia eggs by means of the haw juice with organic acidity and light salt brine; and by coordination of bile and phosphatidase C, decomposing the phosphatide and cholesterol in the eggshells of the artemia eggs, and by coordination of Candida rugosa bacterium and the lipoprotein lipase and active substance secreted from the Candida rugosa bacterium, and papain, decapsulating the artemia eggs, wherein the egg envelopes of the decapsulated eggs have high resistance to papain and lipoprotein lipase so that the reaction can be terminated even no special inhibitor is used and the decapsulated artemia eggs can be obtained. Through the decapsulated artemia egg preparation method improving the hatching rate, the hatching rate of the obtained decapsulated artemia eggs is greatly improved when the decapsulated artemia eggs are hatched, and achieves 93-96%. Moreover, the decapsulated artemia egg preparation method improving the hatching rate is stable in the decapsulating effect and is low in the operating difficulty.
