Problems solved by technology

Among them, the cement cake (block) is too heavy, requires a lot of labor costs, and the seedling harvesting effect is relatively poor; the oyster shell seedling harvesting effect is relatively ideal, but the corrosion resistance is poor, especially the changes in physical and chemical factors such as salinity and pH Severe, the oyster shell fixing base is more likely to be corroded and cause the seedlings to fall off

Embodiment 1

[0026] Example 1: see figure 1 , a preparation method of Hong Kong oyster fixing base of the present invention, it comprises the following steps:

[0027] (1) prepare a plurality of rectangular plastic sheets 1, the length of the plastic sheet 1 is 10-20cm, the width is 2-5cm, and the thickness is 1-3cm, and a circle with a radius of 3-5mm is set on the plastic sheet 1 hole 2;

[0028] (2) String the plurality of plastic sheets 1 into a string, and a plastic tube is arranged between two adjacent plastic sheets 1, and the plastic tube is put on the string, and the preparation process of Hong Kong oyster fixing base is completed.

[0029] The circular hole 2 is located on the plastic sheet 1 at a distance of 2-5 cm from the short side and 2.5 cm from the long side; the radius of the circular hole 2 is 3-5 mm, the rope is a plastic rope, and the inner diameter of the plastic tube is 3 mm. -5mm, the inner diameter is the radius.

[0030] The plastic sheet 1 is provided with ret...

Embodiment 2

[0046] Embodiment 2, this embodiment is substantially the same as Embodiment 1, and its difference is:

[0047]In the present embodiment, the length of the plastic sheet 1 is 16cm, the width is 3cm, and the thickness is 2.5mm. The radius of the circular hole 2 is 4mm. At 2.5 cm from the side, the length of the plastic tube is 1-2 cm, 120 plastic sheets 1 are strung together in a string, and the number of plastic sheets 1 is 1.2 million, and a total of 10,000 strings of fixing bases are obtained.

[0048] Fixation base treatment: place all fixation bases in five 10m 3 In the cement pool, soak in oxalic acid solution with a concentration of 30ppm for 24 hours, then soak in fresh water for 6 hours, and transfer to the outdoor to dry.

[0049] Fixture base pool: When the Hong Kong oyster larvae grow to 300-360μm, and the proportion of eye-spot larvae is ≥30%, put all the fixation base into 10 10m 3 Harvest seedlings in cement ponds. Among them, the density of larvae is controll...

Embodiment 3

[0051] Embodiment 3, this embodiment is substantially the same as Embodiment 1, and its difference is:

[0052] In the present embodiment, the length of the plastic sheet 1 is 16cm, the width is 3cm, and the thickness is 2.5mm. The radius of the circular hole 2 is 4mm. At 2.5 cm from the side, the length of the plastic tube is 1-2 cm, and 120 plastic sheets 1 are stringed into a string, and the number of plastic sheets 1 is 1.8 million, and a total of 15,000 strings of fixing bases are obtained.

[0053] Fixation base treatment: place all fixation bases in eight 10m 3 In the cement pool, soak in oxalic acid solution with a concentration of 30ppm for 24 hours, then soak in fresh water for 12 hours, and transfer to the outdoor to dry.

[0054] Fixture base pool: When the Hong Kong oyster larvae grow to 300-360μm, and the proportion of eye-spot larvae is ≥30%, put all the fixation base into 15 10m 3 Harvest seedlings in cement ponds. Among them, the density of larvae is contro...

Abstract

The invention discloses a preparation method of a Crassostrea hongkongensis fixation medium. The preparation method comprises the following steps that (1) a plurality of rectangular plastic sheets are made and a round hole with the radius being 3-5 mm is formed in each plastic sheet, wherein the length of the plastic sheets is 10-20 cm, the width of the plastic sheets is 2-5 cm and the thickness of the plastic sheets is 1-3 cm; (2) the plastic sheets are strung through a rope, a plastic tube is arranged between every two adjacent plastic sheets, the plastic tubes are arranged on the rope in a sleeved mode, and then the preparation process of the Crassostrea hongkongensis fixation medium is completed. The invention further discloses the Crassostrea hongkongensis fixation medium and an application method of the Crassostrea hongkongensis fixation medium. After being processed through oxalic acid, fresh water and the like, the Crassostrea hongkongensis fixation medium is used as an eyespot larva collection fixation medium; the Crassostrea hongkongensis fixation medium increases the metamorphosis rate of Crassostrea hongkongensis larvas, accelerates juvenile mollusk growth, improves the juvenile mollusk survival ability and increases the juvenile mollusk yield, has the advantages of being capable of being recycled multiple times, light, convenient to use, good in corrosion resistance and the like and is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of shellfish cultivation in modern marine agriculture, and in particular relates to a preparation method of Hong Kong oyster fixation base, the fixation base and a use method thereof. Background technique [0002] Hong Kong oyster Crassostrea hongkongensis is the main economic species of coastal culture in South my country. It likes to live near estuaries or places with fresh water injection. It is mainly distributed in Guangdong, Guangxi and other places. The annual output is more than 1.3 million tons, and the output value is 8-10 billion. Yuan (China Fishery Yearbook, 2013). Compared with other types of oysters, the value of Hong Kong oysters is mainly reflected in their large body, fat meat, and delicious taste. In addition, their market value is much higher than other types of oysters, and they are favored by consumers in Guangdong, Guangxi, Hong Kong, Macao, and some Southeast Asian countries. [0003]...
