Those parent abalones of wild or artificial selection with good economic characters must be chosen in order to avoid close breeding.. Correct breeding techniques must be adopted to obtain excellent germ cells and larvae. The survival rate and disease resistance of juvenile abalone can be remarkably increasedonce the further selecting and culturing are carried out. The rejuvenation is realized once a good breeding condition for the young and parent abalones is created, the adverse culturing condition and technical maloperation are reduced or eliminated. The survival rate of the breeding and young abalonesincrease about 28.9%-31.2%, the survival rate of the grown abalones is high up to 85%-90%.
