Benefits of technology
Problems solved by technology
Physicochemical factors such as salinity and pH change drastically, which can easily cause oyster shell strings to be corroded and cause seedlings to fall off. Therefore, in the history of oyster farming in Hong Kong, no one has directly used oyster shells as a fixing base for seedling collection and cultivation.

Abstract
The invention discloses a manufacture and application method for a cement shell composite type Crassostrea hongkongensis fixation base suitable for Crassostrea hongkongensis to cultivate from collecting fries. According to the manufacture and application method disclosed by the invention, one set of cement shell composite type Crassostrea hongkongensis fixation base with high fry collection efficiency and strong resistance to corrosion is developed by the technical means of material preparation, fixation base manufacture, fixation base processing, fixation base fry collection and the like. According to the manufacture and application method disclosed by the invention, the fry collection area of the fixation base is increased, the metamorphosis rate of the young Crassostrea hongkongensis is improved, the juvenile mollusk growth speed is quickened, and the corrosion function in the saline water and fresh water environment can be effectively resisted. The manufacture and application method is not only suitable for indoor artificial fry collection but also suitable for outdoor natural fry collection. The cement shell composite type Crassostrea hongkongensis fixation base disclosed by the invention is different from the traditional Crassostrea hongkongensis fixation base, such as heavy cement pats (blocks and bars), and shells which are easy to be subjected to acid corrosion by saline water and fresh water, and the cement shell composite type Crassostrea hongkongensis fixation base combines the advantages of the heavy cement pats and the shells. The manufacture and application method has the advantages of high colony-forming efficiency, low cost, easiness in operation, convenience in popularization and the like.
Description
Technical field: [0001] The invention belongs to the technical field of shellfish cultivation in modern marine agriculture, and in particular relates to a method for making and applying a cement shell composite anchoring base for Hong Kong oysters, which is suitable for harvesting and growing Hong Kong oysters. Background technique: [0002] Hong Kong oyster (Crassostrea hongkongensis, also known as oyster) is an important economic oyster species unique to the southern coast of my country. It likes high temperature and low salt environment. It is mainly distributed in the brackish waters of the estuaries of Guangdong and Guangxi, and a small amount of distribution in Fujian and Hainan. This species has the characteristics of large body and fat meat, delicious taste, and rich nutrition, and is favored by consumers. In addition to being eaten fresh, processed into dried oysters, and dried oysters, it is also a high-end oyster deep-processing product such as high-value oyster ex...
