A few days ago, the "Liriodendron chinensis seedlings breeding method" completed by the Liuyang Research Assistant of the Heilongjiang Institute of Chinese Academy of Fisheries Science and others was authorized by the national invention patent. The invention belongs to a specialized method in the field of aquatic product breeding technology, and replaces the seedling cultivation technology of the other fish which is not completely suitable for seedling cultivation of fine-scale oysters in the past, and solves the high mortality rate in the seedling breeding process of the fine-scale oysters. The problem is that the present invention increases the survival rate of the seedlings of the S. pleurotus by more than 50%. The “cultivation method for the seedlings of the squama scales†is to place the fertilized eggs in the troughs in the horizontal trough to avoid hatching until they float up; then, after opening the openings, the acclimatized feeds are used for domestication and cultivation, and the environmental factors such as the cultivation density are controlled to a weight of 10 to 12 at the same time.
