Breeding method of good young triploid oysters

Abstract

The invention relates to the technical field of oyster breeding, in particular to a breeding method of good young triploid oysters. The breeding method comprises the following steps: S1, parent selection, S2, sperm and egg extraction, S3, larva breeding, S4, adherance putting, S5, mariculture and S6, detection. The triploid is high in glycogen content and good in quality and taste, marine buoyant raft culture is adopted, and compared with a traditional mode, the production cost is low, management is easy, the oyster growth speed is high, the individual shell type is regular, the hemps are uniform in size, manual operability is high, the oyster yield is high, products are not prone to being lost, the characteristics determine that the triploid oysters cultured by the method have conditions to enter domestic and international high-grade oyster markets to replace and improve the existing oyster cultivation varieties, so that the huge domestic oyster cultivation industry is really driven to realize industrial upgrading.

Description

technical field [0001] The invention relates to the technical field of oyster reproduction, in particular to a method for breeding oyster triploid good oyster seedlings. Background technique [0002] Oysters, commonly known as sea oysters, oysters (oysters), oysters, oysters, etc., are widely distributed bivalve molluscs. More than 100 species have been discovered so far. They are produced in almost all coastal countries in the world, and their output ranks first among shellfish. . China is rich in oyster resources and has a long history of exploiting this resource. The ancestors in some areas along the southern coast have mastered the technique of planting bamboo to raise oysters as early as the Han Dynasty, which has a history of more than 2,000 years. Since the founding of the People's Republic of China, especially since the implementation of the reform and opening up policy, China's oyster production has continued to grow. After entering the 21st century, it has shown ...

Problems solved by technology

[0004] Chinese patent application number CN201010595675.7 discloses a method for cultivating triploid single oysters. Oyster production, ploidy detection and other steps, the combination of triploid technology and individual oyster seed breeding technology to cultivate new oyster varieties, and at the same time can be produced on a large scale. Regular, beautiful, deep shell and fat meat, etc.”, although the triploid oyster seedlings bred in the above patent documents have a certain glycogen content, but the glycogen content is not high, and at the same time, the production cost is high when breeding. , oyster growth rate is slow, oyster yield is low, which affects the quality and quality of the triploid oyster seedlings bred
