Embodiment 1

[0028] The demonstration flow chart of the large-scale indoor artificial breeding method for Hong Kong oysters on the coast of South China in this embodiment is as follows figure 1 As shown, the specific steps are:

[0029] (a) Parental maturation promotion: On June 10, 2013, 1200 healthy, vigorous, and gonadal individuals were selected as parents in Guandu, Zhanjiang. Using scallop cages, 5 parents are placed in each layer, and each scallop cage has 6 layers. A total of 40 scallop cages are used to promote ecological maturation in a shrimp pond with a salinity of 27-30ppt in a high-salinity shrimp pond. After 2 weeks of rearing, the parental gonads matured synchronously.

[0030] (b) Oxygenated hatching: randomly select 400 parents with mature gonads, clean them, place them in zero-degree seawater to stimulate for 6 hours, dry in the shade for 1 hour, then rinse and stimulate them with normal-temperature seawater for 45 minutes, and place them in In the cement pool of the s...

Embodiment 2

[0035] The demonstration flow chart of the large-scale indoor artificial breeding method for Hong Kong oysters on the coast of South China in this embodiment is as follows figure 1 As shown, the specific steps are:

[0036] (a) Promoting ripening by parents: On June 15, 2013, 1,500 Hong Kong oysters from Deep Bay, Hong Kong, which were healthy, full of vitality and full of gonads, were selected as parents in Shajing, Shenzhen. Use scallop cages, place 5 per layer, and each scallop cage has 6 layers. A total of 50 scallop cages are used to raise fry in the high-salinity Dapeng Marine Biology Industrial Park with a water salinity of 27-30ppt. Mark the pond for ecological ripening promotion. After 3 weeks of rearing, the parental gonads matured synchronously.

[0037] (b) Oxygenated hatching: randomly select 500 parents with mature gonads, clean them, place them in zero-degree seawater for 3 hours, dry them in the shade for 2 hours, then rinse them with normal-temperature seawa...

Abstract

The invention discloses a method for large-scale indoor artificial breeding of Hong Kong oysters in the coastal region of South China. According to the method, a large number of healthy oyster larvae are bred indoors by means of parent maturation, parturition hastening, incubation, larva breeding, adhering transformation, juvenile mollusk breeding and other processes. In combination with the ecological habits of the Hong Kong oysters and the coastal regional characteristics of South China, the step-by-step salinity-reduction breeding pattern that parent maturation of the Hong Kong oysters in a high-salinity environment, the larvae are bred in a medium-salinity environment, and juvenile mollusks are bred in a medium / low-salinity environment is realized, and a solid foundation is laid for production of the larvae of the Hong Kong oysters, development of aboriginal varieties and industrial popularization of the Hong Kong oysters.

Description

Technical field: [0001] The invention belongs to the technical field of shellfish fry breeding in marine agriculture, and in particular relates to an indoor large-scale artificial breeding method for Hong Kong oysters in the coastal areas of South China. Background technique: [0002] Hongkong oyster Crassostreahongkongensis 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 6-8 billion yuan. (China Fisheries 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 that of other types of oysters, and they are favored by consumers in Guangdong, Guangxi, Hong Kong, Macao, and Southeast Asian countries (Zha...
