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.

Embodiment 1

[0016] Embodiment 1: Indoor industrialized seedling picking

[0017] a. Material preparation: At the beginning of March 2012, prepare 18,000 pieces of left oyster shells of the year cleaned by fresh water. There is no carrion or odor on the shells, and the size is 7-12cm; 15 packs of Conch brand cement, 7.5kg epoxy resin, fine Sand and water, mix cement, fine sand, water and epoxy resin evenly to obtain cement-sand-resin mixture, the mass ratio of cement, fine sand and water used is 1:1:0.3, the epoxy resin The dosage is 1% of the quality of the cement dosage; the length is 2.0m polyethylene rope (diameter 5mm) 9000 pieces.

[0018] b. Fabrication of fixing base: Glue 8 pairs of oyster shells on a polyethylene rope with cement-sand-resin mixture (12cm between each pair). After 4 hours of drying in the shade, the cement shell composite Hong Kong oyster fixing base is formed, and every 10 cement shell composite Hong Kong oyster fixing bases are tied into a handful for use. The...

Embodiment 2

[0021] Embodiment 2: natural seedling collection in sea area

[0022] a. Material preparation: At the beginning of April 2013, prepare 360,000 pieces of oyster left shells cleaned with fresh water. There is no carrion or odor on the shells, and the size is 7-12cm; 300 packs of conch brand cement, 150kg epoxy resin, fine sand And water, mix cement, fine sand, water and epoxy resin evenly to obtain cement-sand-resin mixture, the mass ratio of cement, fine sand and water used is 1:1:0.3, the consumption of described epoxy resin It is 1% of the quality of the amount of cement; the length is 2.0m plastic rope (diameter 5mm) 180000 pieces.

[0023] b. Fabrication of fixing base: 10 pairs of oyster shells are glued on a polyethylene rope with cement-sand-resin mixture (every pair is spaced at 12cm). After drying in the shade for 6 hours, the cement shell composite Hong Kong oyster fixing base is formed, and every 10 cement shell composite Hong Kong oyster fixing bases are tied into ...

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 fixing base for Hong Kong oysters, which is suitable for harvesting seedlings and cultivating 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 estuaries in Guangdong and Guangxi, and a small amount is also distributed in Fujian and Hainan. This species has the characteristics of large body, 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 extr...
