Embodiment Construction

[0007] The present invention will be further described below in conjunction with embodiment:

[0008] 1. Harvesting parents: 80-100 oysters with 2-3 years of age and shell length of 8-12 cm were collected from Jiaonan Sea Area, Qingdao, with a trawl net when the water temperature was below 20°C in April-May 2009 as breeding parents.

[0009] 2. Promoting ripening of parents: place the harvested parents indoors for 20-30m 3 In the pool, the initial water temperature is 16°C, artificially cultured unicellular algae and spirulina powder are fed, the full amount of water is changed 0.5-1 times a day, the daily temperature rises 0.5-1.0°C, and the culture is maintained at a constant temperature of 22-23°C.

[0010] 3. Obtaining larvae: During the period of parenting and promoting maturation, observe the changes in the gill cavity of the dense scale oyster one by one every day, and find the parental individuals containing fertilized eggs in the gill cavity, and move them to the hatc...

Abstract

The invention relates to a method for the artificial propagation of ostrea denselamellosa. The method is characterized by comprising the following steps of: fishing parents from a natural sea area; promoting the maturing of the parents in an indoor water body; obtaining D-shaped larvae after the parents finish the discharge of the D-shaped larvae; moving the D-shaped larvae to a pond of 10-20m<3> and culturing; putting in scallop shell attaching bases for spat collection; and culturing the attached spat until the shell length is 500-600 mu m, and then moving to the natural sea area for culturing. Based on the propagation characteristic of the ostrea denselamellosa, the invention establishes the method for the artificial propagation of the ostrea denselamellosa spat by using the steps of properly fishing the wild parents, promoting the maturing of the parents, culturing the larvae, artificial spat collecting, culturing the spat and the like. By using the method for the artificial propagation of the ostrea denselamellosa, the ostrea denselamellosa artificial spat can be cultured on a large scale. The invention is of far reaching importance for developing the artificial cultivation of the ostrea denselamellosa and protecting the natural resources.

Description

technical field [0001] The invention relates to an artificial breeding method of shellfish, in particular to an artificial breeding method of dense scale oyster. Background technique [0002] The dense scale oyster (Ostrea denselamellosa) belongs to the class Lanellibranchia, order Anisomyaria, family Ostreidae, and the genus Ostrea, and generally inhabits the subtidal zone to a water depth of 30m or less. And relatively stable shallow seas are distributed along the coasts of my country, the Korean Peninsula, and Japan. The soft body of dense scale oyster is not only rich in taurine and highly unsaturated fatty acid, but also has the characteristics of low fat, low cholesterol, inorganic salt and high vitamin content, and its nutritional value is relatively rich. However, due to the scattered distribution of the dense scale oyster in the coastal areas of our country and the lack of resources, its economic value has not been exploited and utilized. [0003] In recent years, ...
