Problems solved by technology

This method takes advantage of the characteristics of oyster growth after attachment, but the fly in the ointment is that the left shell (attached shell) of the obtained oyster seed is relatively flat, and the whole monomer is in a relatively flat state, which reduces the value of the single seed

Embodiment 1

[0023] a. High-density seedling harvesting: From June to August 2012, oyster seedlings were produced in Dalian Zhuanghe Marine Shellfish Nursery. Take 30% of Hong Kong oyster hybrid triploid larvae with eyespots and outstretched feet as the seedling harvesting period, and the density is 2 / mL. Use 50 strings of oyster shell attachment bases (1000 pieces) to 5 100L The seedlings are collected in the white bucket, and the seedlings are collected after about 5-10 days, and the juvenile shells are attached to the oyster shells. Among them, the attachment bases are made of perforated oyster right shells and made of plastic ropes. Every two oyster shells are separated by a 2.5cm inflatable tube to form a certain interval. There are 20 oyster shells per string of attachment bases.

[0024] b. Cultivation of juvenile shellfish: use the water in the shrimp pond in the ecological shrimp pond of Dalian Zhuanghe Marine Shellfish Nursery Field as the source of unicellular algae bait after b...

Embodiment 2

[0028] a. High-density seedling harvesting: From June to September 2013, oyster seedlings were produced at the Zhanjiang Marine Economic Animal Experimental Station of the South China Sea Institute of Oceanology, Chinese Academy of Sciences in Zhanjiang. Using 25% of Hong Kong oyster larvae with eyespots and outstretched feet as materials, the density is 2.5 / mL, and 1000 strings of oyster shell attachment substrates (20000 pieces) are used to reach 10m 3 Seedlings were picked in the cement pond, and the seedlings were picked after about 5-10 days, and the juveniles were attached to the oyster shells. Among them, the attachment bases are perforated by the right shell of oysters and made of plastic ropes. Every two oyster shells are separated by a 2.5cm oxygen tube to form a certain interval. Each string of attachment bases has 20 oyster shells.

[0029] b. Cultivation of spat: The artificially cultivated shrimp pond water is filtered through an 80-mesh sieve and used as a bait ...

Embodiment 3

[0033] a. High-density seedling harvesting: From June to September 2013, oyster seed production was carried out at the Guangxi Shellfish Comprehensive Experimental Station. Use 30% of Kumamoto oyster larvae with eyespots and outstretched feet as materials, with a density of 3 / mL, and use 1,000 strings of oyster shell attachment bases (20,000 pieces) to reach 10m 3 Seedlings were picked in the cement pond, and the seedlings were picked after about 5-10 days, and the juveniles were attached to the oyster shells. Among them, the attachment bases are made of perforated oyster right shells and made of plastic ropes. Every two oyster shells are separated by 2.5cm oxygen tubes to form a certain interval. There are 20 oyster shells per string of attachment bases.

[0034] b. Cultivation of spat: The seawater in the ecological shrimp pond is filtered through a 60-mesh sieve silk screen as the source of unicellular algae bait, and the daily feeding amount is 10-30% of the cultivated wat...

Abstract

The invention discloses a method for preparing monomer oyster fries by utilizing the vertical growth characteristics of oysters. The method utilizes the vertical growth characteristics of oyster spats under high density (2-3 pieces / ml) and combines the individual natural falling-off phenomenon of the spats of 20-30 mm; a lot of healthy and complete mid-size monomer oyster fries can be obtained through high-density seedling collection, spat cultivation, spat off-base and other technical means. The monomer oyster fries obtained by the method are different from monomer oyster fries with flat right shells which are obtained by a corrugated plate, a plastic plate and the like and grow in a creeping way, have the original shell forms of the oysters and have more attractive appearance and higher economic values. The monomer oyster fries obtained by the method can be directly cultivated by the utilization of a silk screen mesh cage with a mesh of above 8 mm, an intermediate cultivation process in which a mesh bag with a mesh of less than 8 mm is utilized is avoided, and the cultivation links of the monomer oyster are simplified. The monomer oyster fries have the advantages of being high in growth speed, survival rate, yield and the like.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of shellfish cultivation in marine agriculture, and in particular relates to a method for preparing individual oyster seedlings by utilizing the vertical growth characteristics of oysters. [0003] Background technique: [0004] Oysters belong to the phylum Molluscs, Bivalves, Pearl Oysters, and Oysteridae, and are globally distributed groups. Oysters are delicious and rich in various essential amino acids. They are an important marine biological resource and the most important in the world. It is one of the economic groups of marine aquaculture, and its total aquaculture output and output per unit area rank first among all shellfish aquaculture species (Guo et al., 2006). my country is a big oyster farming country, with an annual output of 3.5-3.8 million tons from 2009 to 2012, accounting for 35% of the production of cultured shellfish, 25% of the total production of mariculture, and more than 70% o...
