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%.

The background survey and tracking survey of artificial reef area in Chenghai Laiwu were carried out before and after reefing in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reefs, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant; total number increased from 23 to 41, which increased by 0.78 times. The crab resources sharply increased by 1.75 times after artificial reef were deployed. Harpodon nehereus and Portunus sanguinolentus , which did not appeared in background survey, now became the dominant species in tracking survey. There were high diversity indexes in artificial reefs area and control area in tracking survey. In conclusion, the results indicated that the fish-aggregating effect of artificial reef site has improved a lot, and the community structure and the habitat environment have been significantly improved.
